No Place Like Gnome
The original sculpture I made from Sculpey. It's a polymer clay that stays soft until baked in the oven. Using some tools and imagination, I created this little guy.
This part takes maybe 8 or 10 hours, depending on how much I fiddle with the details. Then he's in the oven and ready for the next steps.
Mold Me
The first step is to make a base of Klean Klay. It is a non-hardening clay that isn't affected by silicone. I use this to make the bottom of the mold and to fill in any blank areas to save on silicone.
The walls are basic foam core with blue masking tape to seal the seams. The idea is to create a water-tight box with enough space to make a solid mold, but small enough not to waste anything.
Before preparing the silicone, a release spray is needed. A thin coat on the sculpture keeps the silicone from sticking.
The silicone I like is a simple 2-part mixture, much like an epoxy. Mix and pour and in 10 minutes we have a durable and flexible mold.
My original gnome broke his legs getting out of the rubber, but a little super glue and patch up and he's ready for future molds.
A Cast of Six
The casting can be done with just about anything: plaster, wax, plastic. I used a polyurethane plastic. It mixes and pours easily. Cures in 10 minutes and best of all no bubbles.
I only had enough resin for a cast of six, and they are quick and easy to make. This is the easiest part of the whole process.
They even come out warm, like fresh cookies. The chemical process causes it to heat up as it cures.
Primed and Ready (to paint)
Like anything fresh, the gnomes need a coat of primer. The primer sticks to the plastic. The paint sticks to the primer. Everyone is happy.
I paint the gnomes with basic acrylics. I start with dark colors as a base coat and add on lighter colors until the final dry brush of highlights. This technique gives it an older, antique feel.
After the acrylics are cured (few days), I spray on a protective coat of clear varnish. Our dead gnome is done!
I've given away a few as gifts already. I'm thinking of making some more and selling them.
