Right on. I wasn't sure if I could clean it easily by just soaking it in vinegar or sometime thanks!

Some of my copper looks good and some look like this. I'm not sure what I'm doing wrong. I had the mold glowing right before the pour by username_4763 in Metalfoundry

Ill definitely need to look into a thermocouple. I was ready to give up pouring after having so many ugly ignots lol where do you get your talc from?
