I have my master plaster cast taken from the original mold made from my hand-modelled 2007 clay master laid out on a board to prep for the new mold.
I needed to do a little bit of repairs to the sides on this first, unfortunately the original clay model was fired in the kiln a year ago and for some reason I had not taken a plaster master cast from the first rubber mold immediately when it was made as is typical.
That was probably because I had the original clay model, but later forgot I didn’t also have a plaster master and I fired the clay, as a result the original clay model is about 5% smaller from being fired and I don’t want to re-mold that since it is smaller than the other two panels in the set- one of which was fired the other was damaged beyond salvage to fire it but has a plaster master stored away.
The master cast being used now was taken from the first rubber mold made of the compound I used to use that started to tear and shrink early on, as a result the sides were somewhat uneven.
Fixing that now and the mold will start to-morrow, once I have the new mold I can make the second mold I need to have to get started on a plaster mold for pressing terracotta from.
