I bought a coffee grinder (at a yard sale) to make frit. I found crud mixed in with my frit. So… I went on line to find a glass frit maker and got really excited about making frit. Much to my dismay I noe get bits of paint flacking off into my frit. I tried to remove the the paint flakes by adding water to a container hoping the paint would float up and I could pour it off. Sometimes it works and lots of times it doesn’t. Any ideas out there for me to try?
