Hi,
I've been making a few cold cast "metal" resin items, but I'm having an issue- I always thought the best way to achieve a great finish and make it easier to polish up was to dust the mould(brass powder), however no matter how careful I am, how slow or fast I pour the resin into the silicoln mould I end up with around a 50% failure rate where I get a small patch, or two where the metal powder has been washed away by the resin.
I read on smooth ons site they put a layer of mould release over it to hold it in place, but that didn't work for me, it seems a strange idea away! I just wonder if anyone has any advice for me as it's very disappointing to keep throwing expensive bits of resin away! Maybe the powdering the silicon mould technique just isn't any good for reliably casting?
Thanks in advance for any help,
Mark.
