Grace london 7 Report post Posted January 11 (edited) Hello all, I am working on a bunch of ceramic heads, using a stoneware/paper clay I made. I generally bisque to 1170 then use a low matt 1070 to glaze ( generally using earthenware paper clay). So I'm wondering will they be much weaker than the recommended 1280? It's a commission so I don't have the time to test. I feel like I could get away with it, and they also won't shrink as much. Any thoughts gratefully received : ) ...

glazenerd 1,330 Report post Posted January 11 Hi Grace.. Welcome to the Forums. Low viscosity glass begins to form at 1117C: so you are shooting just over that. It would help if you could do a soak/hold for 20-30 minutes at peak temperature. For non-functional use you can probably get by with it, for functional use- no! tom 1 Grace london reacted to this Share this post Link to post Share on other sites
