Welcome to the first of our newsletter “Skill Set” series where we collectively learn a new skill together. First up: Basic molding and casting. Since I don’t want the newsletters to get too long-winded, I’ll mainly be pointing to curated articles and videos that tell you everything you need to know.
To get things started, the best mold-making and casting resource I can point you to is Paige Russell’s class on Instructables
. For our series, we’ll be doing a simple one-part mold, a block mold, and a more complicated two-part mold with registration keys. She covers all three.
Let’s all choose a small, flat object for our first one-part mold (see Paige’s instructions). Also, I recommend buying a casting kit that has everything you need for creating molds and casting several small objects. Molding and casting products are not cheap. A starter kit is the most inexpensive way to get stuck in and then you can invest in stand-alone products if you want to take it further. Here’s the kit
I’ll be using for this series. It comes with small bottles of 2-part RTV (room temperature vulcanizing) silicone rubber for molding, 2-part resin for casting, some modeling clay, cups and stirring sticks.
