Good link Phil. Thanks.

I was etching some 3mm x 10mm aluminium flat bar brackets in sodium
hydroxide so I could paint them. I forgot a batch and left them etching
overnight. In the morning there was absolutely no bracket metal left at all,
only a white paste in the bottom of the container - bugger!
