Ah…I had to look up TruSilver. I’m using something similar from Rio…anti-oxidation casting grain. I’ve actually had problems trying to get it to take a nice patina. Thanks for the info on the temperatures…I’m casting at around 1865°F (1018°C), which is at the top end of what they recommend…I was having a problem with it not being fluid enough. Using a KayaCast vacuum system. Sounds like you have a really nice setup!
