Hi
I'm making my first plastic resin cast and the mold for it using the tutorial. One difference to the tutorial however is that the object I am making a mold of is something I've make in air-dry modelling clay. I've spent quite a bit of time making the original so bit worried about pouring the silicone for the mold onto the clay object - will it break the clay down or is there some way to prepare the clay (varnish or something?). I've put a test of dried clay in water and it has broken down in five minutes. Can anyone who has done this sort of thing before advise please? Thanks in advance.
