A practical demonstration on making an open-faced mould.
Open face moulds suit models that have a wider base than the top.
Make your object in clay
surround with (baffels?) fix with g clamps and seal edges with clay.
Mix your plaster.
Plaster should achieve this consistency.
Flick plaster in to begin with (some techniques do differ)
Pour in plaster carefully preferably in a corner not on the clay (causes bubbles).
watch out for leaking.
Jiggle table ot tap baffles...causes bubbles to rise.
wait.
