|Hayes rubber mold and protective plaster cast.|
Before taking the rubber off the clay model they cover the whole thing with plaster to make a three piece "protective" plaster cast; another couple of day's work.
Once the plaster sets they open up the cast and strip the rubber mold off the clay model; a little like taking off a rubber glove. Once the clay model is free it is set aside and the then empty rubber mold is placed back into its protective casting.
I spent the day today down at the foundry to do some final corrections to the eyebrows and eyes in the "wax". The wax allows me to "cut/refine" with more precision than the clay. I can also smooth out unwanted bumps and hollows a lot easier in the wax.
So, now it's up to the foundry to produce the bronze.That will take 10 weeks or so. Finally, it will be time to do a little patina work to add colour. See you then!
