What is the best refractory for a forge?
ITC-100: Refractory Coating for Forge Efficiency ITC-100 is known for its ability to reduce fuel costs and help your forge reach higher temperatures in a quicker time frame. ITC-100 is also more impervious to flux than Satanite alone and can help prolong the lifetime of your forge lining.
How many burners do I need for a propane tank forge?
For first forge, and one made out of a 20lb tank, I would recommend one burner. Two burners will use up a lot more gas, and won’t net you anything when you are just starting out.

Refractory cement is used as the insulation material in foundry furnaces and forges. Its maximum temperature is 2900 Degree Fahrenheit . You’ll need around 86 lbs of material per cubic foot, not counting mixing losses.
Is plaster of paris good for a forge?
The refractory can be made from cement, sand, fireclay mixture, or a mixture of plaster of paris. If plaster of paris is used, it can be mixed with perlite and sodium silicate (available in hardware and garden stores) to provide an extremely heat resistant refractory.
Can red brick be used for a forge?
Last but not least, note that the bricks near the top of the forge may need replaced periodically. Red bricks withstand heat fairly well but they’ll still break down over extended periods of exposure to high temperatures and outdoor elements. Good luck with the build and have fun!.
How long does a 20 lb propane tank last on a forge?
Answer: Depends on how hot you burn it, if you both burners, the way I use it a con average 8 hours on a 20 pound tank.

How hot does a single burner forge get?
Typical forge welding temperatures for a propane forge are accepted as 2,300 degrees F, and common forging can be accomplished at a lower temperature.
How do you use refractory coating?
The applied Heat Guard Refractory Coating should be air dried for minimum 24 hours and then slowly raise the temperature to 600°C at 20 to 25°C / hr and then to operating temperature at around 50°C / hour. For large coating thickness ( more than 2 mm) adequate air dying is required to avoid cracks.
How do you treat refractory cement?
The curing process begins when the water is added to the castable and begins to react with the cement. The process ends when the material is hard and has achieved its final set. Curing behavior is directly impacted by both the ambient and castable temperature.
What is Satinite?
The Satanite is a refractory cement that insulates the surface of the wool, this keeping more of the heat in the chamber ( it does not reflect or absorb, just insulate). The ITC-100 is a highly heat reflective coating that greatly reduces the heat loss.
Does Kaowool contain asbestos?
Kaowool is made from ceramic fiber. No asbestos involved.
Will Kaowool burn?

Chemical Properties. A small amount of organic combustible binder will burn out at approximately 300°F (149°C).
What is refractory wool?
Alumino silicate wool (ASW) Alumino silicate wool, also known as refractory ceramic fibre (RCF), consists of amorphous fibres produced by melting a combination of aluminum oxide (Al2O3) and silicon dioxide (SiO2), usually in a weight ratio 50:50 (see also VDI 3469 Parts 1 and 5, as well as TRGS 521).
How do you use Kaowool?
Kaowool Rigidizer is applied by brushing, dipping, rolling, and spraying. Suitable respiratory protection and ventilation are required when applied by spraying. Materials to be rigidized should be free of all grease and oil. Kaowool Rigidizer receives its bonding action from the removal of physical water.
How do you make refractory cement for a forge?

How hot can refractory cement get?
High temperature refractory cements are extreme temperature insulation that can withstand operating temperatures up to 2900°F.
Is plaster of Paris fireproof?
Plaster of Paris is fireproof and is also a material that is ideal for heat insulation. Hence, it does not develop cracks as it heats and sets. Its main component is gypsum.
What temperature will plaster of Paris withstand?
The maximum working temperature of plaster is 1,200 °C (2,200 °F), so higher melting temperature materials would melt the plaster mold.
What kind of brick do you use for a forge?
A firebrick or refractory brick is a ceramic brick made from refractory material that can withstand high temperatures. You need the best fire bricks because they are useful for lining the inner surfaces of furnaces, kilns, and forges. They have low thermal conductivity and are excellent for forging or fireplaces.
