Question

Where do I find the liner?

Community Answer

If you google "kaowool" and fire clay, it will give you various resources for it. Kaowool is a fireproof insulator, so your forge holds heat. I know of forges that use firebrick, but it's a lousy insulator. Ideally you can use both; the brick for the durability (and ability to withstand the heat without breaking up), the wool and fire clay for insulation to protect your forge shell.

Question

Can I use an old water tank to make a forge?

Community Answer

Yes; try using a tank that is 12 inches in diameter for optimal results. Using insulating wool is best.

Question

Can I fire bricks inside and have a concrete forge outside?

Community Answer

You could use the fire bricks on the inside and concrete on the outside, yes. But be sure to insulate the concrete well and to not cool it too fast after working so it doesn't crack.

Question

Do I need an inline spark to run my propane forge?

Community Answer

You do not. You just need an ignition source to start the propane. The fire itself will keep going, and once it gets hot enough it will actually reignite if it blows out or goes out when you adjust the flame.
