Which course is recommended for making a lighter, more permanant lifecast bust?
I'm trying to figure out which course would be best suited. I already have had my lifecast done, and I have my Ultracal bust, I've used it, sculpted on it... but in a lot of resources online and videos I see people referring to making lighter, hollow, more permanent molds. I am not sure I understand this process, or what materials are used. I've seen some, where they are using silicone, and resins, and making "jacket molds" with pour tubes, or slushing ultracal in several layers.... and I just haven't figured out if there is a course or video here that would be best suited to teaching this as a complete topic. I'm even hazy on what the best terminology is here. I've heard words thrown around like "mother molds" and "jacket molds" or "case molds." Any suggestions or info to clear things up? Thanks!
