Silicone mold

Learn to Make Silicone Molds

Mold-making allows you to create multiple copies of a three-dimensional work of art or any other object. As an artist it opens up the world of limited editions. Suddenly you can make a sculpture and reproduce it many times in plaster, resin, or even bronze. If you’re a prop-maker, mold-making allows you to make multiple realistic copies of objects for the stage. This 4-day workshop will give you the hands-on experience of creating a silicone mold and making your first cast from it in plaster.

Instructor Neil Grant will lead you through the step by step process of brushing layers of silicone onto a reference piece, creating a cut seam, making a mother mold and casting the piece in plaster. At the end of the workshop you’ll have learned a number of key mold-making skills:

  • How to estimate the materials needed
  • How to design a basic mold with a single cut seam
  • How to apply brushable silicone and deal with difficult areas using a thickening agent
  • How to create a two-part mother mold
  • How to prepare your mold for casting
  • How to cast in plaster

Alternative mold-making and casting techniques will also be discussed so that the student gains a broad awareness of options.

July 1 & 2 – 9am to 4pm
July 3 & 5 – 9am to 12pm

There is a $50 materials fee payable directly to Neil on the first day of the workshop.
Please bring a brown-bag lunch on July 1 & 2.
