Plaster legs and base composition
I've poured my plaster
and now it's dried but there's no way I can get the legs out without
destroying the mould. But that's ok because it's composimold and it's
reusable!
Using a stanley knife I
split the edges and carefully removed the plaster. 2 dinosaur legs,
fantastic! It's not perfect and there's a few lessons learnt here:
- The plaster is not that strong. It's ok for large volumes but smaller finer details like the tips of the claws broke a little when removing from the mould. Composimold did sell a composistone product which sets harder or other products like resin might be more suitable
- There are some bubbling imprints on the mould. Again composimold sell another product for this to help prevent bubblings staying on the surface of the piece being cast. Also they recommend using a brush to wipe bubbles off the surface after pouring the liquid.
So now to create the base:
1. I bought a small bonsai vase at a hardware store, filled it with plaster
2. Glued the dinosaur legs into position
3. Glued down a sandy mixture over the entire base and over the feet
4. Undercoated black then white
