Polyhedron

Thanks for the info. There are some small pointy details that are breaking off, are there any tips for reinforcing them? Maybe by using a different mixing ratio for the plaster? Or is it because I use too much mold release, does that affects things?

Hi, I just made a slip casting mold. There are some little holes/bumps in my mold because of too much mold release I think. Can I fix this with making a little bit of plaster (same as mold) and carefully smoothing and filling up the holes? Are there other methods?
