It’s my sisters birthday (again) and I’m expected to do something arty. She’s picked up my childhood interest in Pokémon, her favourite being “oddish”, so naturally I guilted myself into making her a small clay sculpture. How hard could it be?
I started with a wire armature which I enveloped in masking tape. I’m using air drying clay, the usual materials at this stage is wire and aluminium foil but I could use anything to bulk out the frame since I’m not putting this thing in the oven. Masking tape is also nice since you can trim and prune it into any shape you like without worrying about crumpling it into a hard mass you can’t unravel.
The tricky thing about air drying clay is the dreaded cracking. Cracks can appear everywhere if you leave your sculpture out to dry naturally. You’ll need a very slow drying process to stop this from happening. So every time I finished working with the sculpture I’d cover it in a light plastic bag to restrict the air flow, to really slow down that drying.
If cracks did appear I mitigated against them by mixing the air drying clay with water to make a kind of slurry which is referred to as “slip” and fill in the cracks and smooth it over.
After it had dried, I wanted to sand the piece down to a nice smooth finish, I picked up some hobbyist sandpapers for this job since regular sandpaper is way too rough. After sanding the larger scratches away I continued using finer and finer grit. I went from 200, 400, 600, 800 to finally 1000 grit sandpaper.
I had to get this sculpture done in little over a week, and made many mistakes. The first one being that after I finished sanding the sculpture, I applied a couple of base coats of gesso. I then made the big mistake of painting it without sealant. Gesso is not water resistant so what happened is the gesso undercoat started to sag, tear and bubble in a few areas.
Major disaster!
