Jabberwocky: Making the molds

Myself and Kane started making the molds by lying all three sculpts down on boards and building clay half way up the sculpt making sure there are no undercuts, the we tied/clamped them together around the clay, then sealed any gaps with more clay and poured over the plaster. When the plaster had set we pulled the boards away and were left with this:


Next all the clay was peeled off leaving the sculpt in the plaster, bored holes into the plaster (this makes sure that the molds fit together perfectly).


Next three layer of soft soap over all the plaster and the sculpt, dabbing it off with water between each layer, this stops the plaster sticking together and allowed you to separate the two halves of the molds. 


Next more boards and more clay.


And more plaster:


Then the mold can be pulled apart and the sculpt removed. Then into a drying room over night and its ready to be used.
