Was going to make a very simple forge by just stacking up some 9" long K-23 2300 degree insulating fire bricks and blowing a propane torch wand into the forge mouth.
Sole purpose would be to heat 1084 blades up to quench. Just to about 1800 degrees till the magnet don't stick and then shut it off.
Are 2300 degree bricks sufficient?
Do I apply the flame directly to the blade or do I make a point NOT to directly flame the blade?
Would a propane weed burning torch or work-bench torch wand get the forge hot enough? HF has one for $20 that is apparently pretty hot.
The pics are of a HF torch and a small fire brick forge, similar to the one I might build.
