Copper Oxide Powder
Copper Oxide powder for fusing creates wonderful blue bubbles when fired sandwiched in between clear glass.
You can use it with any type of glass including float, Bullseye Glass and Spectrum 96 Glass. We reccommend applying this with a fine sifter to achieve an even application. Take care not to apply too thickly. (The more thickly you apply it, the less likely you are to get a good even finish)
Price is per 50g Jar
Safety Note: wear a dust mask when sifting.
