So I am a newbie trying to get into casting gold in a simple pour furnace. I am able to get the printer and plaster to work perfectly. However, when I melt the gold at the temps specified by the manufacture (RioGrande - 18K White Gold), the gold doesn’t flow thru the part until it freezes. I am only trying to make a simple ring band, so I don’t think I need additional spurs. I just poured at 2200F and it still froze in the mold. Other than the furnace limits, is there any limit to how you can melt the gold?
Any advice from anyone else who went thru this process?
