Has anyone used a sheet of plastic, that has been vacuum formed to the shape of a plaster mould, as a way of quickly removing clay that has been pressed into it? Im keen to find alternative ways of releasing the clay quickly on my homemade ram press. I live in the UK and sourcing the materials to make an air release mould is very pricey and difficult. If anyone knows whether the idea above would work or has an alternative suggestion, I would really appreciate the help!
Is wood a good material to make molds because i have three that i sometimes use for hexagonal plate forms and would like to use more, if not then what can i put on the wood to keep clay from sticking or something?
I just mixed a bunch of colored slips for the studio using trimmings from Laguna #65. I left the studio for 2 weeks and I come back and all the slips I mixed have turned black and smell something fierce. How can I fix or prevent this for next time cause I definitely just burned $20 of mason stain. Would a vinegar ratio have killed bacteria growth? Should I not have used trimmings and just mixed a clay base?
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 w
