I find it always best to pour when your material is like water coming out. It makes for better pours, better looking bars and helps keep any splashing down like you get when your pouring with lumps. Directions of how much to use vary depending on your Results your getting now. Try a little at first as you can always add more if needed. This flux thinner will help you get all the gold out of your black sands or ore if that's what your smelting. This package is a 5 Parts Flux & 1/2 part thinner by volume or 10%....Not by weight
