I just finished my senior year of high school, and I had done a lot of experimenting with slip casting at home (we didnt have the resources/time to do it at school). I kept my used slip in a few empty plastic coffee containers, and my fresh stuff in a large square plastic container. I hadnt been able to use my slip for about a month, but when i went to check on it there’s green stuff floating all around in it, which I think is mold.
It’s a stoneware clay, and I kept my container out side, with a bag covering it, because I dont think the lid has an air tight seal on it. What should I do with this slip? Should i let it dry out if it’ll kill off the mold and just rework it after? Would mixing it or adding something help?
