Hi Stefan -

I really don't understand the chemistry; Adam is quite knowlegeable
about it. There is some information on the chemistry in this article:

You are right, I should have said I added one 4 litre jug of Hcl to
two 4 litre jugs of distilled water to get 12 litres of etchant.
(There is a limit to "the magic of chemistry" <g>)
