Sorry if duplicate but I have looked into forum history before asking. I have a little project in mind and I need I think abt 3gr of 18ct gold. Looked cooksons sheet gold quite pricey. then I looked at same weight in casting grains 18ct yellow seems cheaper. Am I right to take that if I have grain gold I can melt it and roll into my own sheet ? sounds logical but wanted to see if I wont make pricey experiment here. thank you !
