Copper Carbonate

Copper Carbonate is not as strong in colour as Copper Oxide, it gives a nice even colour with less speckles and uneven tone.  Great to combine with other oxides.
A 3 – 7 % addition to the glaze will produce a green.
Please see how it reacts with other oxides in the photos.  Experiment with combining it with other oxides and see what happens.

All photographs show the oxide used in combination with JSC earthenware transparent glaze fired to 1140ºC. The results will vary depending on what glaze you use.
