Hi Everyone,
I am very new to this forum and would appreciate some advice ...I have designed a pendant with Illustrator which I want to make in acrylic (perspex). I eventually want to have it cast in silver but before that, I gather I first need to make a rubber mould and cast in wax before sending off to a foundry to be cast in silver. The question is how much smaller in percentage terms will the finished piece in silver be compared to the original perspex pendant? I really need to know this before I create the pendant as I don't want to make it either too small or too large!! Any help would be much appreciated.
Carl
