How to Make a Mold of Your Sculpture

Mushroom Man by Amanda Day

Today we have a tutorial from Amanda Day DeVirgilio of 'Doll Makers Dream' showing us how to make silicone molds of our sculptures and use the molds to cast hydrostone sculptures.  She is demonstrating with a polymer clay sculpture, but the casting methods used would be the same for air-dry clay sculptures.

In this tutorial, Amanda has sculpted a fairly contained sculpture of a mushroom man.  'Contained' meaning there are no protruding limbs, gaps or open spaces.   The mold-making compound that Amanda is using is a super flexible brush on silicone rubber called Rebound 25 .  She also uses 'Stoner- Rapid Release', a releasing agent in spray form, and Hydrostone to make the cast.
(Note: Amanda is located in Australia, brand names mentioned may not be available everywhere.)

  1. Thank you! I've been looking for a good tutorial on this for ages. I'm finally going to have a go at making a Gizmo from the original Gremlins movie.

Thank you very much for taking the time to comment! ;-)
Sorry I had to re-instate the 'word verification'...I'm getting far too much spam in the comment box.
