Casting resources
There are times when I think the art of sculpting in/casting glass is simply the art of shopping a lot–it seems to take a LOT of supplies. Sometimes you can repurpose things (as I mentioned here) but other times you simply need the right tools. I’ve compiled a list of places I buy and learn from; if you know of others please comment and I’ll add them to the list.
This list is also available as a downloadable PDF. I usually update the online version faster than the PDF, though, so refer here first. If you’re going to distribute it, however, please give me some credit (and let me know you’re doing it). Thanks.

Ecorche (live-size reference models) and other castings of human and animal bones. Assorted races, ages, medical conditions, both sexes, extremely realistic. Very useful for to see where bones or muscles attach when sculpting, or for incorporating impressions into your work. Warning: These are skilled reproductions from the real thing, so they’re not cheap. If all you’re looking for is, say, a skull for Halloween, there are cheaper places to find them.

Truly beautiful lead crystal billets in a variety of colors. Very helpful staff, but it’s wise to call and ask before using a new glass from Gaffer—they can have very precise heating requirements and the website doesn’t always spell them out.

Really marvelous portrait sculpting instruction, on DVD, in workshops and in books.

Fabulous tutorials and videos on making molds, life casts, mother molds, etc. These guys have literally written the book(s) on flexible mold-making and they’re extremely eager to help. The site is a bit confusing, but very information-rich. Unless you know precisely what you want, search for a project demo that LOOKS like what you want to do, and then track back the supplies list to figure out what you actually want to buy. Or save time by just calling them to ask.

Acrylic forms, fiberglass fabric and chopped fibers, RTV silicon, lots of interesting stuff to use for models and molds. Good online catalog.
