If your still unsure hang a clean nail into it for a few minutes, the nail will acquire a copper coat. Process is called plating by immersion.

thanks, I will try the nail. It is such a brilliant blue, I always think of antifreeze being yellow green buy perhaps they took it out of a tractor nyears ago when antifreeze was blue. Any ideas of what would be left after putting low current through a copper electrode in this stuff, if it is copper sulfate?

Antifreeze is blue here in UK which was the reason why I mentioned it that's all. If you are using copper electrodes then copper sulphate will be in the end solution. Copper electrodes are used for refining the metal to make it purer, not to produce copper metal. With other electrodes ie carbon, you will have sulphuric acid as your product solution. If other metal electrodes are used then generally the product will depend on it's affinity for electrons. Anything above copper in electronegativity will give you a sulphate salt of the metal used.
