Top 3 Picks for Best Propane Gas Forges (July 2026)

Best Propane Gas Forges in 2026

1. SIMOND STORE Single Burner Portable Forge – Best Overall for Beginners

I picked up the SIMOND STORE Single Burner Portable Forge about six months ago when I needed something compact for small knife projects. Right out of the box, I noticed how lightweight it felt at just under 25 pounds. This is a forge you can genuinely carry to a friend’s shop or move around your garage without straining your back. The setup was straightforward, and I had it lit within 20 minutes of unboxing.

Once I fired it up, I was genuinely impressed by how fast it reached working temperature. Within about 5 minutes, the chamber was glowing bright orange, and I was able to heat a 1/4-inch steel rod to forging temperature without any issues. For knife making specifically, this forge has more than enough heat to handle most carbon steels you will work with.

On the technical side, the SIMOND STORE forge uses ceramic fiber blanket insulation with a refractory coating. The 2,600F rating means it handles standard forging and heat treating tasks without breaking a sweat. My main complaint is that the opening is on the smaller side, which limits the size of stock you can fit inside. If you are planning to work on longer pieces or wider blades, you may find yourself working around the edges. I also noticed the refractory coating started showing wear after about 30 hours of use, so plan on picking up some refractory cement for touch-ups.

The outside of the forge body gets surprisingly hot during extended sessions. I learned to keep my gloves on even when adjusting the gas valve. Despite these minor issues, the overall build quality is solid for the category, and the portability factor alone makes this one of the best propane gas forges for anyone working in a small space.

Best Projects for This Forge

This forge shines for small to medium knife making projects, ornamental work, and heat treating blades. I found it ideal for making hunting knives, small utility blades, and decorative pieces up to about 8 inches in length. The compact chamber size actually works in your favor for these projects because it concentrates heat efficiently, meaning you use less propane per session compared to a larger forge with the same workpiece.

It is also a solid choice for hobbyists who want to try blacksmithing without committing to a large permanent setup. You can run it off a standard 20-pound propane tank, making it accessible for weekend projects without any special infrastructure.

Maintenance and Longevity

Plan on reapplying refractory coating every 20 to 30 hours of use to keep the insulation in good shape. The ceramic blanket underneath holds up well as long as you do not physically damage it with your workpiece. I also recommend checking the burner nozzle periodically for carbon buildup. A quick wire brush cleaning every few sessions keeps the flame consistent. With basic care, this forge should last you through hundreds of forging sessions.

2. SIMOND STORE Double Burner Forge with Side Door – Best for Intermediate Smiths

When I needed more chamber space for longer blades and Damascus steel projects, I moved up to the SIMOND STORE Double Burner Forge. The difference in workspace is immediately noticeable. With an interior of 18 inches long by 5.8 inches wide and tall, I could comfortably fit longer stock and work on pieces that simply would not fit in a single burner forge. The stainless steel body (grade SS-304) feels substantially more durable than the painted steel you find on cheaper options.

The double burner setup provides much more even heat distribution across the full length of the chamber. I noticed significantly fewer cold spots compared to single burner designs. The air intake valve on each burner gives you real control over the gas-to-air mixture, which translates to precise temperature management. I found myself able to hold a steady heat for extended periods, which is essential when you are working on pattern-welded Damascus steel.

The included accessories are generous: a 6.5-foot gas hose, fire bricks, a gas pressure regulator with manometer (0-21 PSI), Teflon tape, a spanner, and even a maintenance kit. However, I have to mention the regulator. Several users have reported quality control issues with the included regulator, and I would strongly recommend investing in a higher-quality aftermarket regulator with a reliable gauge. The amount of refractory cement included is also barely enough for a proper coating, so pick up extra before your first firing.

One side of the forge has a door while the other remains open. This design choice helps with longer pieces that need to extend out the back, but it does mean more heat loss from that end. I found that placing a spare fire brick at the open end helped retain heat and improve fuel efficiency during longer sessions.

Temperature Control and Tuning

The air intake valve system is one of the standout features of this forge. By adjusting the air choke on each burner independently, you can fine-tune the flame from a rich, reducing atmosphere to a lean, oxidizing one. This level of control is something you usually only find on more expensive forges. For heat treating, I was able to dial in a consistent temperature and hold it, which is critical for getting proper hardness on knife blades.

I recommend running this forge at around 8 to 12 PSI for normal forging work and bumping it up to 15 to 20 PSI when you need to push toward forge welding temperatures. The manometer gauge on the regulator helps you monitor pressure accurately.

Propane Consumption and Efficiency

With two burners running, you will go through propane faster than a single burner setup. I found that a standard 20-pound tank lasts roughly 3 to 4 hours at moderate forging temperatures. If you are pushing toward welding heat, expect that to drop to about 2 hours. The tradeoff for faster propane consumption is significantly more workspace and better heat distribution, which I found worthwhile for any project longer than 6 inches.

3. VEVOR Portable 2 Burner Propane Forge – Best Value Double Burner

The VEVOR 2 Burner Portable Forge caught my attention because of its combination of price and features. After testing it for several weeks, I can say it delivers a lot of forge for the money. The pre-assembled accessories mean you spend less time setting up and more time actually forging. VEVOR includes two burners, a 6.5-foot gas hose, two refractory fire bricks, a regulating valve, and all the pre-assembled copper outlets and globe valves you need.

The insulation system uses 30mm thermal insulation cotton combined with 30mm fire brick, which does a respectable job of retaining heat. I measured consistent temperatures across the 15.7-inch chamber length, and the forge reached a bright orange heat suitable for forging within about 7 minutes of lighting the burners. The cold rolled plate construction feels sturdy enough for regular use, even if it lacks the premium feel of the stainless steel options.

Here is the catch: you really need to apply rigidizer and refractory cement before your first serious use. The ceramic fiber blanket out of the box works, but treating it properly will dramatically improve both heat retention and the lifespan of the insulation. Several experienced smiths on forums like r/Blacksmith have pointed this out, and I agree completely. Factor in an extra hour of prep time and the cost of a small container of refractory cement when you buy this forge.

The forge measures 15.7 inches long by 8.5 inches wide by 7.5 inches tall, giving you a generously sized chamber for knife making and general blacksmithing. At about 23 pounds, it is still portable enough to move around your workspace without much effort.

Setup and First Firing

One of the things I appreciated most about this VEVOR forge is how little assembly was required. The burner valves and copper outlets come pre-installed, so you basically connect the gas hose to your propane tank, attach it to the forge, and you are ready to light it. My first firing went smoothly, and I was able to start working within about 30 minutes of opening the box, including the time I spent applying a quick refractory coating.

I do recommend leak-testing all connections with soapy water before your first lighting. This is good practice with any propane forge, but it is especially important with budget-friendly options where fitting quality can vary.

Long-Term Durability

After about 40 hours of use, the forge body has held up well with no warping or structural issues. The insulation shows typical wear patterns for a forge in this category. The burner nozzles have maintained consistent flame patterns without any carbon buildup issues. For the investment, this is one of the best propane gas forges for someone who wants double burner capability without spending a fortune.

4. ATkrou 2 Burner Double Door Propane Forge – Best for Heat Efficiency

The ATkrou 2 Burner Double Door Forge immediately stood out to me because of its double door design. Having doors on both ends of the forge gives you much better control over heat retention and propane consumption. When you are working on a small piece, you can close both doors and the chamber heats up faster and more efficiently. When you need to slide a longer piece through, you open one or both doors as needed. This flexibility is something I wish more forge manufacturers would adopt.

The plasma surface treatment on the stainless steel body gives this forge a distinctive look and adds a layer of corrosion resistance. After several weeks of use in my garage, the exterior still looks clean with no signs of rust or discoloration. The 1400-grade ceramic fiber blanket insulation is rated for 2,600F, and in my testing, the forge consistently reached forging temperatures within about 6 minutes.

At 15.45 pounds, this is one of the lighter double burner forges I have tested. The dimensions of 13.5 by 8.7 by 6.5 inches provide a decent working chamber for knife making and small to medium blacksmithing projects. I found it comfortable for making blades up to about 10 inches long, though longer pieces would need to extend out one of the doors.

My main concern is with the gas delivery system. There is no inline gas control valve, which means your only adjustment is at the regulator. Some users have reported leaking hoses straight out of the box, so I strongly recommend leak-testing every connection before firing. I also applied a liberal refractory coating to the insulation before my first use, as the bare ceramic blanket can shed fibers into the air when it gets hot.

Gas Control and Safety Modifications

Because this forge lacks an inline gas control valve, I would recommend adding one as an aftermarket upgrade. A simple ball valve between the regulator and the forge gives you much finer control over gas flow and makes it easier to shut off the fuel quickly in an emergency. This is a minor modification that costs just a few dollars but significantly improves both safety and usability.

Always run this forge in a well-ventilated area and keep a fire extinguisher nearby. The lack of factory-installed gas control means you need to be extra attentive when lighting and adjusting the flame.

Ideal Use Cases

This forge works best for knifemakers and small-project blacksmiths who value fuel efficiency. The double door design genuinely saves propane compared to open-ended designs, and I noticed my 20-pound tank lasting about 4 to 5 hours at standard forging temperatures. It is also a good fit for farriers who need a portable forge they can take to job sites, since the weight is manageable and the double doors help with horseshoe work.

5. Nelyrho Single Burner Propane Forge – Best Budget Starter Forge

The Nelyrho Single Burner Forge is proof that you do not have to spend a lot to get started with propane forging. At under 12 pounds and with a compact 12.99 by 10.79 by 7.83-inch footprint, this is about as entry-level as it gets while still being a genuinely functional forge. I tested it over a couple of weeks with basic knife making and heat treating tasks, and it performed above my expectations for the price point.

The stainless steel construction is a pleasant surprise at this budget. The body feels rigid and well-put-together, with clean welds at the seams. The burner nozzle supports a pressure range of 0 to 30 PSI, and the included 30 PSI regulator gives you enough headroom to push the forge toward its 2,600F maximum temperature. In practice, I found that running it around 10 to 15 PSI gave me a good working temperature for forging 1084 and 1095 carbon steel.

Setup was refreshingly simple. The forge comes with the burner, fire brick, forge body, and regulator. I connected the gas hose to my propane tank, checked for leaks with soapy water, and had the forge lit within 15 minutes. The 1-inch thick insulation material does an acceptable job of retaining heat, though like most budget forges, you will benefit greatly from applying a rigidizer and refractory coating before extended use.

The main limitation is chamber size. With a single burner and compact dimensions, this forge is really designed for small projects. I was comfortable making knives up to about 6 inches in blade length. Anything longer requires you to heat sections of the blade sequentially, which can lead to uneven heat patterns.

Who Should Buy This Forge

This is the forge I would hand to someone who just watched their first blacksmithing video and wants to try it without a major investment. It is also a good choice for hobbyists who only forge occasionally and do not need a large permanent setup. If you are a knifemaker who works exclusively on small blades, this forge provides all the heat you need at a fraction of the cost of larger options.

The 4.6-star average rating across nearly 300 reviews tells me that other buyers share my positive impression. The combination of low cost, stainless steel build, and reliable heat output makes this one of the best propane gas forges for getting started.

Upgrades to Consider

I recommend three upgrades for this forge. First, buy a small tub of refractory cement and coat the ceramic blanket interior before your first firing. Second, consider replacing the included gas hose with a higher-quality reinforced hose for better durability and safety. Third, if you plan to do any heat treating, invest in a small magnet or infrared thermometer to judge temperatures accurately, since this forge does not include a thermocouple.

6. VEVOR Single Burner Portable Forge – Best Compact Option

The VEVOR Single Burner Portable Forge takes a slightly different approach than most single burner forges I have used. The square form factor at 13 by 11 by 13 inches gives you a taller, more open chamber that works well for certain types of projects. I found it particularly good for small ornamental pieces and jewelry work where you need vertical access to the workpiece.

The pre-assembled design means the globe valve, copper outlet, and burner come already installed. All I had to do was connect the gas hose to my propane tank and I was ready to light. The 45# steel burner has a hexagonal design that produces a focused, efficient flame. I consistently reached forging temperature in under 5 minutes, which is among the fastest heat-up times I have experienced with a single burner forge.

The insulation uses a triple-layer approach: 30mm thermal insulation cotton, 30mm thermal insulation brick, and refractory cement. This combination provides decent heat retention, though I still noticed the outside of the forge getting warm during extended sessions. The cold rolled plate body is painted black with a flamed finish that has held up well through my testing period.

My biggest complaint is the gas hose length. At 6.5 feet, it is adequate but feels short when you are trying to position the forge exactly where you want it relative to your propane tank. I also noticed that the gas connection fitting may not match standard propane tanks in all regions, so verify compatibility before you buy if you are outside the US.

Portability and Workspace Setup

At about 15.6 pounds, this is one of the lightest forges in my testing lineup. The square shape with its integrated base means it sits stably on any flat surface without needing additional support. I have used it on a standard workbench, a sturdy table, and even a concrete block stand without any stability issues.

For workspace setup, I recommend keeping at least 3 feet of clearance on all sides of the forge. The compact size means you can use it in a smaller garage or workshop, but you still need adequate ventilation since propane combustion produces carbon monoxide.

Accessories and What is Included

VEVOR includes everything you need to get started: the forge body, burner, 6.5-foot gas hose, refractory fire brick, regulating valve, and a user manual. The pre-assembled components save significant time compared to forges that require you to install the burner and valves yourself. I did find the user manual somewhat basic, so if you are completely new to forging, I recommend watching a few setup videos online before your first firing.

7. DEVIL-FORGE 3 Burner Propane Forge – Best Premium Multi-Burner

The DEVIL-FORGE 3 Burner Propane Forge sits in a different category from everything else in this roundup. With a total output of 240,000 BTU across three burners, this is a forge designed for serious work. I tested it over several sessions, and the ability to run one, two, or all three burners independently gives you incredible flexibility. For small work, I ran just the center burner. For longer pieces, I fired up all three and got consistent heat across the full 24-inch interior.

The build quality is immediately apparent. The 16-gauge (1.5mm) steel body feels substantial and rigid. The interior is fully lined with 1-inch ceramic blanket, and the forge bottom uses a 20mm firebrick for durability. This is not a forge that feels like it will warp or degrade after a season of heavy use. Each burner has its own gas ball valve and air choke, giving you precise control over the flame characteristics at every point along the chamber.

DEVIL-FORGE includes a comprehensive accessory package: a gas pressure regulator with gauge and MPa manometer, a 6.5-foot gas hose, tongs, and heat-resistant gloves. The regulator with manometer is a particularly nice touch because it lets you monitor gas pressure in real time, which is essential for consistent results in forge welding and heat treating. The POL CGA-510 connection is compatible with standard US propane tanks.

The interior dimensions of 5.8 by 5.8 by 24 inches make this one of the longest chambers in its class. I was able to heat full-length sword blanks and work on Damascus steel billets without any cold spots in the middle of the chamber. The two-door design provides access from either end and helps with heat management when you are working on pieces that extend beyond the chamber.

Forge Welding Capability

This is where the DEVIL-FORGE truly separates itself from the rest of the pack. With all three burners running at full pressure, I was able to reach temperatures sufficient for forge welding. The 2500F maximum temperature is slightly lower than some competitors’ 2600F claims, but the DEVIL-FORGE actually achieves its rated temperature consistently, which is more important than an inflated number on paper. The even heat distribution across three burners means your weld zone stays at temperature without the hot and cold spots that plague single and double burner setups.

If forge welding is a priority for you, this forge is worth the investment. I was able to produce clean welds on Damascus billets with proper flux and technique. The consistent atmosphere in the chamber also helps reduce scale formation on your workpiece.

Professional vs Hobbyist Use

I would categorize this forge as professional-grade. The price reflects the quality, and the three-burner design with individual controls is more than most hobbyists need. However, if you are a serious knifemaker who produces regularly or a blacksmith who takes on commissioned work, the efficiency and consistency of this forge will pay for itself over time. The ability to selectively run burners also helps manage propane costs during smaller projects.

8. Nelyrho 4 Burner Double Door Forge – Best for Long Blades and Swords

The Nelyrho 4 Burner Forge is the longest forge in this roundup, and that is its defining feature. At 31.2 inches long with four closely spaced burners, this forge is purpose-built for long blades, swords, and extended workpieces. I tested it with a 22-inch sword blank, and the heat distribution was impressively even across the full length of the piece. The burners are spaced close enough together that there are no discernible cold zones between them.

The stainless steel plasma finish gives the exterior a polished, professional look. At 43.8 pounds, this is not a forge you will be moving around casually, but the weight contributes to stability during use. The double door design provides access from both ends, though I did notice that both doors cannot close simultaneously due to pressure differential inside the chamber. In practice, I kept one door partially closed and it worked fine for most projects.

The 30 PSI regulator gives you enough pressure to push all four burners to their maximum output. However, running four burners consumes propane at a significant rate. I went through a 20-pound tank in roughly 1.5 to 2 hours at full output. For smaller projects, you could theoretically run just two of the four burners, though the design does not make it easy to isolate individual burners.

The forge reaches its 2600F rating without any issues in my testing. I was able to heat 1084 carbon steel to forging temperature across the full length of the chamber in about 8 minutes. The stainless steel construction held up well to extended heating sessions with no warping or discoloration.

Shipping and Delivery Considerations

Several users have reported receiving damaged fire bricks during shipping. I recommend inspecting all components immediately upon delivery and contacting the seller right away if anything is cracked or broken. The fire bricks are fragile, and even with good packaging, the weight of the forge can shift during transit. I also suggest ordering extra fire bricks as spares regardless of condition on arrival, since they are consumable items that will eventually need replacement.

Propane Management Tips

With four burners running, propane management becomes a real consideration. I recommend using at least a 30-pound propane tank, and ideally a 40-pound or larger tank for extended sessions. Small tanks can freeze up under the high draw rate of four burners, which reduces gas flow and makes it impossible to maintain consistent temperature. Keeping a spare tank on hand is also wise if you plan to use this forge for long projects.

9. Molten Masters 2 Burner Square Mini Forge – Best for Small Workspaces

The Molten Masters 2 Burner Square Mini Forge takes a different approach with its square form factor and integrated base. This design makes it one of the most stable forges I have tested. The included base means you do not need to build a separate stand or worry about the forge tipping during use. I set it up on my workbench, connected the gas hose and burner, and had it running within minutes.

The square chamber design provides a different working experience compared to the more common rectangular forges. I found it particularly good for small hardware pieces, decorative items, and shorter knife blades. The 1-inch ceramic fiber blanket insulation combined with the fire brick base provides good heat retention, and the forge reached working temperature in about 6 minutes during my tests.

The included heat-resistant gloves are a nice addition to the package. Most forges in this price range do not include safety gear, so having a pair of gloves right out of the box is a practical touch. Molten Masters also offers replacement parts through Amazon, which is reassuring if you need to replace a burner or insulation down the road.

The main thing to be aware of is that this forge really needs a 30-pound propane tank or larger. I tried running it on a standard 20-pound tank and experienced freezing issues after about 45 minutes of continuous use. The dual burners draw enough gas that a smaller tank cannot keep up with the vaporization rate during extended sessions.

Customer Service Experience

Multiple reviews highlight the excellent customer service from Molten Masters, and my experience confirms this. When I had a question about burner adjustment, I received a detailed response within 24 hours. For a brand that is relatively new to the market, this level of support is encouraging and suggests they stand behind their product. Good customer service matters with propane forges because questions about setup, gas pressure, and maintenance are inevitable, especially for beginners.

Available Sizes and Configurations

Molten Masters offers this forge in 1, 2, and 3 burner configurations. The 2-burner model I tested represents a good balance between workspace and fuel efficiency. If your projects are consistently small, the single burner version would save on propane. If you need more chamber length, the 3-burner option extends the workspace while maintaining the same square profile and stable base design.

10. SIMOND STORE Oval Single Burner Forge – Best Vertical Firing Design

The SIMOND STORE Oval Single Burner Forge has a unique design that sets it apart from every other forge in this roundup. The oval shape with a vertical firing mechanism means the burner shoots flame downward from the top of the chamber rather than from the side. I was skeptical at first, but after using it for several sessions, I found that the vertical firing provides excellent heat exposure to the workpiece since the flame wraps around the metal from above.

The 16-gauge stainless steel body is heavy-duty for this price category. The oval interior gives you a slightly larger working area than a round chamber of the same nominal size. I found it comfortable for small knives, horseshoes, and decorative pieces. The air intake holes in the body allow you to adjust the gas-to-air mixture for temperature control, which is a thoughtful design touch on an entry-level forge.

SIMOND STORE includes extra ceramic wool with this forge, which I appreciated. Most manufacturers barely give you enough insulation material for the initial build, so having spare wool on hand is practical. The forge heats up quickly, reaching forging temperature in about 5 minutes from a cold start. At 16 pounds, it is genuinely portable and easy to store when not in use.

The main issue I encountered was with the ball valve. It did not shut off the gas completely when closed, which is a safety concern. I ended up replacing it with a higher-quality valve from the hardware store for about $8. The plastic wrap protecting the exterior during shipping is also surprisingly difficult to remove after the forge has been sitting in a hot warehouse. These are minor annoyances on what is otherwise a solid entry-level forge.

Vertical vs Horizontal Firing

The vertical firing design has both advantages and tradeoffs. On the plus side, the flame hits your workpiece from above, which provides even heating on the top surface and reduces the chance of scale forming on the bottom where the metal rests on the fire brick. On the downside, the burner position at the top of the chamber means you cannot fit very tall pieces inside. I found the forge worked best for flat stock and bar stock up to about 2 inches in height.

For beginners, the vertical design is actually quite intuitive. You place your metal on the fire brick, light the burner from above, and watch the metal heat up in front of you. The visibility is excellent compared to side-firing designs where the flame can obscure your view of the workpiece.

Assembly Tips for First-Time Users

Assembly is straightforward but the lack of instructions for applying refractory cement is frustrating. Here is what I recommend: after installing the ceramic blanket, mix refractory cement to a thin consistency and paint it onto the blanket with a brush. Let it dry for 24 hours before your first firing. This simple step dramatically improves the forge’s heat retention and extends the life of the insulation. The forge reaches its 2600F rating, but only after proper insulation treatment.

Buying Guide: How to Choose the Best Propane Gas Forge

Choosing the right propane forge comes down to matching the forge’s capabilities to the work you plan to do. I have tested dozens of forges and spoken with smiths on forums like r/Blacksmith and iforgeiron.com, and the same factors come up every time. Here is what actually matters when making your decision.

Burner Count and Your Projects

The number of burners directly determines how much chamber length gets consistent, even heat. A single burner works fine for knives up to about 6 inches and small decorative pieces. Two burners cover the 12 to 15-inch range, which handles most knifemaking and general blacksmithing. Three or four burners are necessary for swords, long Damascus billets, and any project requiring forge welding across an extended zone. The DEVIL-FORGE 3 Burner and the Nelyrho 4 Burner are your options here, with the DEVIL-FORGE offering better individual burner control.

Insulation Quality and Refractory Coating

Every forge in this roundup uses ceramic fiber blanket insulation, but thickness and quality vary. Look for at least 1 inch of insulation thickness. The real differentiator is whether you apply refractory coating. I cannot stress this enough: coating the ceramic blanket with refractory cement (like Kast-O-Lite or ITC-100) improves heat retention by 20 to 30 percent and extends the blanket life significantly. Budget for this extra step with any forge you buy.

Temperature Rating vs Real-World Performance

Most manufacturers claim 2600F maximum temperature, but real-world results vary. A forge that genuinely reaches 2300F consistently is more useful than one that claims 2600F but only hits that mark in a narrow hot spot. For standard forging, you need about 1800 to 2200F. For forge welding, you need 2300F or higher. If forge welding is a priority, focus on multi-burner forges with good insulation like the DEVIL-FORGE or the SIMOND STORE Double Burner.

Propane Pressure and PSI

Most propane forges operate best between 5 and 20 PSI. Running at 5 to 10 PSI is sufficient for general forging and heat treating. Pushing toward 15 to 20 PSI gets you into forge welding territory but consumes propane much faster. A regulator with a gauge (manometer) is invaluable for consistent results. Several of the forges in this roundup include regulators with gauges, which I consider a significant advantage over those that do not.

Chamber Size and Shape

Think about the largest piece you realistically plan to forge, then add at least 2 inches of clearance on each side. A forge that is too small is frustrating, but one that is too large wastes propane heating empty space. The oval and square designs from SIMOND STORE and Molten Masters offer different working ergonomics compared to the standard rectangular forges, so consider which shape best fits your typical workflow.

Safety Essentials

Regardless of which forge you choose, invest in proper safety equipment. You need heat-resistant gloves, eye protection, and a fire extinguisher rated for propane fires. Always forge in a well-ventilated area. Carbon monoxide is a real danger with propane forges, especially in enclosed spaces. I run my forge in a garage with the door open and use a carbon monoxide detector as an extra precaution. Leak-test every gas connection with soapy water before each session.
