Jerry,

I have even used the taste test on suspected cold blue. I will wipe the oil off, smell the area and if no smell can be detected, and I feel there is cold blue, a touch with the tip of the tongue will give the "coppery" taste and you know. A small spot of cold blue is sometimes not detectible by sight if done right, but the other tell-tale signs are there.
