woodwalker Posted July 2, 2010 Share Posted July 2, 2010 I haven't been on the forums for years, but I recently got an idea to lost-wax cast a ring. I have tried searching various sites to find out more on this subject (I have found a good deal at instructables.com), but I have no idea what to use as investment. It doesn't tell you on any of the sites. Can someone help me out? I had thought about using Plaster of Paris, but I have no idea if it can withstand the heat (I'm going to be casting copper) I also decided to take a page out of the ancient's book, and use clay. No go. I am somewhat impatient, so I did not wait long enough for it to dry. So exploding mold. Funny, but unpleasant. So, to recap, what is the investment used to lost-wax cast copper? Can I use Plaster of Paris? Also, I'm not sure if this is where I should be posting, but it seemed to be the best fit. Quote Link to comment Share on other sites More sharing options...
