[QUOTE="CaptainInsano25, post: 23239, member: 1974"] Hey guys, I'm hoping to get some info on why my ceramic gold is not coming out the color I want it to. I use a PenCeram 87-Y gold for my ceramic alloy and when I'm finishing the gold and after sandblasting, it's a beautiful golden color. Yet when I'm degassing in the oven, it comes out dark and reddish. The alloy calls for degassing from 1200-1800F(650-980c). I imagine it is because my degassing temps are too high...? Here are the specs of what I'm degassing at: Predry/Dry time- 0:00 Low Temp- 1200F Vac Level- High Start Vac- 1200F Heat Rate- 117 Vac Release- 1788F High Temp- 1800F No Hold Cool Temp- 1700F Any help would be much appreciated, Thanks [/QUOTE]
