a friend of mine went to bransom, mo a couple of weeks ago and came back with the most beautiful and colorful chunks of something - i thought it looked like slag glass but she says the lady she bought it from said it was not slag glass but crytals ground up and then these gorgeous rock things made. anyone ever heard of this? i'll have to get some pics next time i'm at her house. she has one that's yellow with red, a cobalt blue one, turquiose one, green striped one and more. wonder if you could tumble it. might have to swipe one. think she'd notice? ;D

Hey Kim, that's does sound interesting. I'm not sure what she meant by "ground up crystals", but you can grow your own crystals. In fact, when I drill Quartz in my drill press, and I leave the water the the trough and let it evaporate, I will have a bunch of small crystals lying on the bottom. I wonder if I kept drilling and producing more Quartz powder and then add a little dye before the water evaporates, if the crystals would take on the color? I may do that this winter and see what kind of larger crystals I can produce.

Crystal growing is a very fascinating science. Some like halite will form as water evaporates, or form by depositing. Silicates, quartz, beryl will form by pulling. The Choralski pulling method for emeralds makes beautiful crystals. I have used grown crystals for faceting. Some grow by seeding, some grow with electrical stimulation, some need stimulation and pressure. Good luck, good hunting.

This sounds like something I'd like to try...what's "pulling"?

Hello Kim,
Slag glass can be very beautiful, especially when you have the bright colors all swirling around each other.
I met one individual that tried to tell me that slag glass is obsidian, and that the very bright color varieties are the rarest of all of the obsidian. It is funny what people can think up to make a sale!
A photo would be great!
Enjoy,
John
