Re: Heater for Etchant Bath

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
