No, I'm not a stalker, rather the beginning of the months lets me see stats of where hits are coming from before search engines take up all the top30 places.
I appreciate the kind words many of you have about Northfur
I'd like to clarify a few things about prosthetics.
Like youthculture said, slush cast is a build-up of 3-4 layers of latex in the molds making a hollow latex shell.
It's only glued down around the edges, so it'll have less expression. But it's useful for those on tight budgets and they're pretty tough and the most durable for being glued on and removed, lasting a dozen applications of more. It's like peeling off a band-aid. This is what Cinema Secrets, Reel FX and a few others use.
Cold foam latex is a sandwich of slush cast latex layers on the outside with expanding polyurethane foam filling the inside. I usually don't recommend it for gluing onto your skin as a prosthetic because it'll have thicker edges that make it hard to blend into your skin. Cold foam is best used as a mask like Kagena's work (I think they're cold foam as well?), where they're painted or furred and possibly attached to a strap, spandex hood or made into a full head mask and not glued on at all. Without being glued on, they'll last for many years.
Hot foam latex is a soft foam that's whipped up and baked in an oven. It's soft, extremely flexible and since it's filled, it'll come into more contact with your face and will give the best expression of these materials. But it needs some care when removing since it can rip, a remover would be recommended for this. They'll last 10 or so applications, possibly more. This is what Lyonshel, Scream Team, FX Faces and Woochie Pro use.
So really, the decision between materials comes down to 3 things: budget, durability and realism. Choosing which is most important to you and you'll be able to choose which material is best for your needs.
My partner and I use all 3 materials, so there are alot of options.
Also, I'd recommend avoiding spirit gum for the larger prosthetics, it's ok for beards, hair and small noses, small horns or pointed ear tips, but for anything larger, like a brow, full face, larger ears, larger horns, etc.; you'd want to use Pros-Aid, Pro Adhesive or Surgical Adhesive. Many costume stores have these, several online have them as well. I usually do, but because of it being winter, they can freeze during shipping and that'll ruin them. Also, these adhesives smell alot nicer.
BTW, I'm always open for suggestions of new sculptures~
