Hi,

Has anyone had a go at making copper oxalate (copper carbonate+ aqueous oxalic acid or aqueous copper sulphate+ aqueous sodium oxalate) for blues?
I would imagine that the flame would be cooled by the carbon monoxide or carbon dioxide gases produced by the thermal decomposition of the copper oxalate.

It could work I suppose. When copper oxalate is decomposed by heat it forms copper metal, so it would have to be reoxidized, which would likely cool it even more. It could certainly work, although I wouldn't expect it to work any better than the copper carbonate starting material.
