I am trying to get information on vacuum casting (on a budget as much as possible) as despite all tricks and techniques (including those mentioned in your forums and videos) I usually still have at least a few, if not tons of bubbles in my finished products. I have been casting for a short while now, with my main interest being bits of nature as inclusions in small objects destined for jewelry. I have been using Castin Craft brand products (plastic molds, resin and mold release), and have also tried EnviroTech resin which I noted no difference. I am wanting to move into silicone molds to have more custom shape options, but not unless I can take care of these pesky bubbles! Any help, info, or links would be much appreciated!
