Review on 🏺 Optimal Plaster 4lb Pottery & Ceramic Casting Compound by Monica Russell

I bought this to make a slide mold. Attention: NOT FOR CLOSED FORMS is written on the back of the packaging. I made a solid mold and it didn't work for slip casting. The clay never dried up. Before using it, I left the mold for 3 days so that it had to dry. Maybe I did something wrong or I had a bad batch. This will probably work well for a clay shape. I just wouldn't recommend it for slip casting.
