Most likely a solution of boric acid (roachkiller) and borax when supersaturated into hot water it makes just about any cloth flame reistant (difficult to start burning and immediately self extinguishes when the source of flame is removed). I have used that solution for quite a while of some canvas chute protectors I made and test several years ago.I think I'm going to try this.
IIRC I remember reading that Vern Estes would make his own wadding by soaking toilet paper in a fireproofing solution, but don't know what that solution was.
I liked the suggestion in the video to use lettuce for recovery wadding. Biodegradable, sustainable and environmentally friendly.
And if you have a misfire you can put it on your BLT. Cheers.
The ingredients iirc are fairly safe, in large enough doses they are toxic, so dont breath the powders, drink or bath in the solution or pour it in your eyes.....
Boric acid is also a naturally occuring chemical.
7oz Borax
3oz Boric Acid (Roach killer powder, needs to be pure boric acid, no other pesticides)
2qts water
Heat water and stir in other ingredients until dissolved, then soak the roll of tissue or paper towels or whatever and allow to dry. As the water cools some of the solids will precipitate out. The paper or cloth after drying should no longer support flame, a torch placed on it will burn it but it will go out as soon as torch is removed.
