Copper blue.....

Gabbert will make a nice turquoise blue when mixed with the copper oxide. We used to mix a very small quantity with about 100 pounds of freshly washed cullet - right in the paper drum. You just roll it around on the ground for awhile to mix - the little bit of moisture from the washing process makes the powder stick to the cullet. Let it sit for a day and then charge as usual. It would probably mix easier if you fritted the glass first as Pete suggest - but I have had good results by just mixing it with the cullet as is. I was using a top fired gas melter.
