Okay, before I go in depth with this, let me say that the end result I am looking for is my items made in silver, and repeatable. That being said, here is what I need help with. For the prototype design, I ordered the model in the white detail material. It has given me some fantastic results as far as resolution and the design came out perfect. I need to make a mold of it. I have access to a guy that makes resin models all day long, cast from silicone molds of his. (Think 40k little model type things and that will be pretty close.) So, my first question is, with him having a vacuum chamber and the silicone for molding already, will that work for a mold for a piece of jewelry? Second, what kind of wax do I need to use with said mold above to get perfect reproductions to have cast in silver? We are going to have to do most of this ourselves, save for the actual silver casting, and neither of us has worked with wax before, so neither of us has any idea of which wax would be best. When we make the mold do we need just the sprue or do we need to mold in a vent as well for the wax? Thanks, and I look forward to hearing your answers.
