kiln casting

I want to get into kiln casting. In a book on the subject, the product Shellspen Ceramic Slurry, from Johnson Atelier Scuplture Supply, is recommended. I can't get any response from them, ie, e-mails returned, 800 number says it's disconnected. I also can't get anywhere with trying to contact Ransom and Randolph, the other supplier mentioned in the book as a source of material for ceramic shell molds. Anyone know where I can get this product or a comparable one?
The book I found is "Glass An Artist's Medium by kohler. Any other suggestions?
I would welcome any help I can get. I've been working in ceramics and Stained glass as a serious artist (well, not tooooo serious) for over thirty years. Haven't found anyone in my area that's into glass casting and I'd love to connect with people who are.

Hi again John...
Most casters I know use a 50/50 mix by volume of #1 Pottery Plaster and 200 mesh silica flour. By weight is slightly better, but I just put bigger scoops of silica and slightly smaller scoops of plaster to approximate by weight. You can get both ingredients at your local ceramics supplier if you live in a big enough town.
I know some folks who use R&R, but it's pretty pricey and IMHO doesn't warrant the extra expense. If you're starting out, plaster and silica will work just fine. I've done 40 lb castings in it, with fiberglass shorts added to strengthen the outer shell of the mold.

I agree Carol if you want some EPK or China Clay to beef up your mold why pay the extra bucks just buy that from the pottery store and add small amounts. Also vermiculite/fiberglass will do the same thing by adding strength to the mold.
A Burning Question

As an aside, for all you casting fiends, opps, friends, I've been designing a jewelry box with a nautical theme. I know some things about rope work after 20 years in the Navy, so it was just a matter of time before I took all the advice Delores has given me and cast a knot or two. The trick is to get it in the plaster and out so that what's left looks like a knot.
After several false starts it occurred to me; ROPE BURNS! So I tied up a flat turk's head with a five pointed star on top, cast it, burned the rope out like you would wax and cast it.
The short story is IT'S GREAT! There was a bit of residue, like soot but not nasty at all, and my air brush blew it right out. So, if you have a "knotty burning question," there's the answer.

You'll have to send a photo, I'll bet it's great
