I tried out the rubber latex moldmaking material I found on clearance at Hobby Lobby. I made a mold of the bottom of this bowl.The latex looks like thick white glue, but smells horrible. I used it under the exhaust fan above Mama’s stove top.

Instructions say apply with a paint brush, at least 3 coats, allowing each coat to dry. Three days later, I have this:Decent impression, still stinks!
