Making our first press mould
It always seems so simple: a bag of plaster, a bucket of water, and you have read the instructions. “How hard can it be?”
Step 2: Check the mould box. Are the boards snug against each other? Have you sealed the seams with clay and clamped everything tightly? Your mould box might look like a makeshift little house, but if the plaster stays inside, it’s good enough.
Step 3: Coat the clay form and all the wood with green soap. Better be on the safe side, so you can extract your form from the plaster. So brush generously with green soap and use a soft brush.
