 Hi, I am using the Basic Coaster Mold 893, I have made a plaster of paris mold for the mold to set in so that the top stays in shape but I am still getting a small rise on the top, I cant get where the glass sits flat, what can I do, thanks.

Hi Alicia,

I would suggest either supporting the center part during the casting procedure or once you have demolded the casting, flip the coaster over and pour a little bit of resin in the center well to bring it to even.

If the rise is significant, you may have to invest in a new mold.
