ic_sizzle,

I have also used the etching technique to which you alluded in post 35172 and ferric chloride.    I keep my cold ferric chloride solution in a capped plastic bottle with a screw-on cap.   I put that inside a ziploc bag.  And I put that into a plastic box.

I like to do things as simply as possible.   To heat the etchant, I just pull out the plastic bottle with the ferric chloride, set it into a larger-diameter uncapped cylindrical plastic bottle, and pour boiling water in the space between the two plastic bottles.    Then just wait 20 minutes.    This makes my ferric chloride a quick etcher.

Hope this helps,
Alan
