Re: alkaline etchants

Yes, there is an etchant that is considered alkaline.  It apparently is used commercially and is discussed here:

  Are there alkaline etchants?

  Sure, I can change the name to just Etchants.

  I've moved the other files/folders I've found about etchants into that folder. So if you've recently created a folder about etchants and can't find it, look in there.

  I'm changing it to "Etchants" now.
