All the companies listed make high quality dependable products.

These companies sell billets of casting glass. Casting glass differs from standard blowing cullet. Casting glass is formulated specifically for casting will not (usually) devitrify when cast and it comes in many colors. As you might suspect casting glass is more expensive than cullet.

Color Rods

These are the companies that sell color (colour) rods for furnace working. I have not listed all those companies, and there are many, that sell rods for torch working.

Tools, Nuts, Bolts, Stuff

These three companies sell everything hardware and then some. Harbor Freight sells Chinese made products, some good and some as you might expect not so good. It's hard at some time or other to avoid buying from Harbor Freight. Cheap diamond tools? Harbor Freight has them. I purchased a sandblast unit and exhaust on the cheap from them. Seems to be well made and the exhaust works fine even if it does sound like a cyclone. McMaster Carr and W.W. Grainger are the old stalwart "we sell everything", and they do, companies. I must have bought 50 squirrel cage blowers and chicken timers from Grainger in the early years.
