CS_P02: Two-Part Mold Making and Cold Casting

Box molds are a simple and versatile way to get started with resin casting. But they have one big problem. What if your positive doesn’t have a flat side to glue to the bottom of the mold box?

That’s where two-part molds come in. Two-part molds allow you to cast positives with more complex shapes. They also allow you to cast hollow pieces using a technique called slush casting.

This hands-on class will teach you everything you need to know to make a two-part mold: building a clay bed, mounting your positive, properly applying for mold release, pouring the two parts of the mold, and more.

Note: This class has three half-hour-long periods waiting for rubber and mold release to cure. You should bring a side project to work on during these times.

Prerequisite: Mold Making and Plastic Casting 101 class highly recommended for those new to the mold making.

Recommended Clothing: The materials used in this class will permanently bond to anything they get on. It is strongly recommended you wear old work clothes and shoes you won't mind getting stained.
