Looked at this video http://www.youtube.com/watch?v=oOLV7jY64KM, polishing a cabochon. I am surprised at the tiny amount of water used with the diamond trizac discs.
Has anyone had the chance to test it, or see it in action?
I did search the board, but nothing turned up.
Only curious at present, have just spent too much money in glass

thanks and best wishes, seachange
