1 Pound of the best Flux Thinning compound I have used so far. 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 thats what your smelting. If your just melting Gold or Silver with Borax or Flux and need it thinner to pour this is the mix for you. If you just want to add it right into your flux a good place to start is a 3 Part Flux & 1 Part thinner or even 1/2 part thinner. This ad is for 1 pound of Flux Thinner, other items in the photos are not included but just for example.
