This week I have been doing loads of tests including strength, joining and colour tests.
My tests were successful on a small scale but now I have tried to work on my final pieces which are on a much larger scale, I am having problems.
I am having issues de-moulding from the plaster mould and I have had to chisel the plaster off which is damaging the pieces.
I have tried different sealants and release agents including shellac, PVA, wax release (gel and spray) and have tried these methods on both wet and dry moulds but still haven’t had any luck.
Today, I am going to try and vac form over my original models to give me a acrylic mould which hopefully will work successfully so fingers crossed.
I know this is a really old post but, have you tried liquid soap. I used to grate soap into a jar then pour over hot water. Let it cool and jell, then use a layer or 2 inside the mold as a release agent.
