So, I was ROTFLMAO at this... Goofer's dust is, generally speaking, usually made considerably near to the following formula, regardless of who's making it (sort of like a meatloaf, there is a basic recipie to follow, though some people do add or take out certain things): Sulphur, graveyard dirt, red pepper, salt, snake skin/powdered insects. Again, 99% of formulas at least LOOSELY will fall under those guidelines (and I took out a few of my personal additions to that formula, hehe, for the purpose of keeping my kickass recipie mostly to myself.) There is at the very effing least graveyard dirt and some snake skin or powdered bug in the recipie, and I'v yet to hear a recipie lacking either of those ingredients. >:-/
I'll tell ya one thing I know for sure - Goofer dust is not pale blue talc. ;)
So, if you see a jar of talc, and it says "Goofers Dust," you probably are not buying anything of the sort.
