The way you do your wax is pretty much the same thing except I don't put a mason ring in the bottom..never thought about doing it. I use my 4 lb pour pot also. With some of my designs I'll melt about 40 oz. in one...as the little chuncks melt down you'll have plenty of room for stirring, adding fo, etc. The reason I like the dbl boiler method is I can keep my thermometer in it to keep track of my temps. It's just the way I started doing it and it works for me.
