I once found this recipe (perhaps on this forum) for mixing a substance for chamber casting.
2 oz. Sulfur
3 oz. Powdered Lampblack
3 drops oil of Camphor
As I'm not exactly sure where to procure "powdered lampblack" and "oil of camphor"
does anyone have experience with substitutes?
I tried this with straight sulfur once, and was lucky to get the plug out of the chamber - it had stuck so hard... (even though the chamber had been lubed) I suspect the lampblack helps in that regard.
