'Skullpture Series - Moose: Gaia' (Bronze Skull - Phase 23) by Shane Wilson (carved bronze antler sculpture)

The next patina to be applied is the 'Moroccan Blue', on the base and the lower portion of the moose skull. The principle component of this patina is cupric nitrate and it is applied on the hot, but not too hot, bronze surface.

In this case, I applied the patina with a large round bristle brush and both painted and flicked the patina onto the surface.

The image above shows the cupric applied to the heated bronze.

With cupric nitrate it is important to watch the heat closely so as not to scorch the patina, which would result in a rainbow coloured effect.

The second image shows the same patina after it has been quenched with water.

The metal is then reheated to remove moisture from the bronze, prior to the application of the final patina, a combination of cupric nitrate, ferric nitrate, chromium oxide and yellow ferric oxide, called 'Italian Green.'
