[TheForge] Making Ferric Chloride etchant

[Bruce Freeman]

Buy a jug of muriatic acid.  Add scrap iron.  (Flammable, explosive
hydrogen gas will be given off, so do this outside, using a container
not tightly sealed.)  When acid will dissolve no more iron, the red
solution is Ferric Chloride.

I had heard rumors that they were removing it, is why I bought 6
bottles 
last trip in. Last year it was still on the shelf, thou geek didn't
know 
what or where.
