Copper Carbonate (basic) has many uses. In this listing it is to make beautiful turquoise blue bubbles in kiln. Sift a very fine layer from a distance to the glass. Too much and bubbles get big and can pop.

I should have used fused glass but I found my old garage window is fusing very well and doesn't crack after some time. It would be a waste to just bin it. So I found an awesome way to recycle it by adding Copper Carbonate and making cool bubbles..

Blue glass is from a wine bottle (Blue Nun).

5g will last for a long time.

Use in a kiln or microwave kiln, to create beautiful blue bubbles between two layers of fused glass.
