ClayCat Posted March 23, 2023 Report Share Posted March 23, 2023 Hello! For clarification I’m using low fire earthenware clay 06 white clay EM330 from laguna clay I bisque fired yesterday and forgot to raise the hours on the timer for the kiln so it automatically shut off but I opened it this morning and the clay looks pretty vitrified… it does look delicate but is white not grey. I did notice a few had a few spots though! Do you think I should re-bisque? this order is time sensitive and needs to ship by Friday/tomorrow. Should I just glaze it? Do you think it’ll be okay?

Min Posted March 23, 2023 Report Share Posted March 23, 2023 Hi and welcome to the forum! This is a difficult question to answer, we don't know how long the kiln fired or how hot it got or if your glaze fire will be hotter or cooler than the bisque fire was supposed to be. Given that it's a lowfire talc/ball clay body it shouldn't off gas a huge amount but it's a crap shoot. Quote Link to comment Share on other sites More sharing options...
Mark C. Posted March 23, 2023 Report Share Posted March 23, 2023 The bisque will absorb glaze more if underfired less if overfired . That the deal. In ceramics every detail is important Next fire put some cones in so you know whats going on If you fire bisque to 06 and you know your glaze application at 06 then its important to go to 06. If you go less or more temp than glaze application will most likely be a different outcome Rae Reich and Pres 2 Quote Link to comment Share on other sites More sharing options...
ClayCat Posted March 24, 2023 Author Report Share Posted March 24, 2023 @Mark C. I decided to bisque again to not risk losing the artwork and I’m glad I did too. I read what you wrote and decided to not take the risk. Chilly, Rae Reich, Callie Beller Diesel and 1 other 4 Quote Link to comment Share on other sites More sharing options...
