After doing a few batches of resin eyes, I’ve gotten nice enough results to document the process. It’s not a perfect product, but these type of eyes are a great way to test out designs and create a custom anime character.
A few basic safety rules: follow the instructions for these products very precisely, especially mix times, temperatures and ratios. Use a ventilator and gloves when handling the liquid resin components and aerosol sprays. Tie back long hair and loose clothes. Work in a well ventilated room, away from kids and pets.
First, making the mold:
I used an empty tofu tub, but any sort of cheap plastic container can work. The bottom is filled with modeling clay, which I’ve roughly leveled. Pressed into that are some decorative glass gems, corresponding in size to 22mm eyes. The lot is coated in mold release spray – follow the instructions carefully.
First, mix carefully and pour the ClearCast resin. This stuff needs to stay pretty warm to degass properly, so it should be warmed before mixing and during the first 10 minutes of setting. I like to go over it with a lighter to kill bubbles on the top. After about an hour, I add my eye cutouts on top and nudge them into place with a toothpick.
