What is the difference between Armour Etch & Etch Bath?
Armour Etch cream is made to be brushed onto a stencil covered glass or mirror item. Important: Armour Etch is NOT intended to etch a solid panel and should NOT be used for this purpose. You will see blotches (which are usually manufacturing defects or stains) and brush strokes. Etch Bath is made to dunk or submerge a glass item into it to frost. In order to be able to drink out of these glasses, you will have to protect the inside of the glass from getting etched. I would also leave a small amount of the rim of the glass clear or un-etched. If you decide to submerge the glass into Etch Bath, you will have to fill the glass will something like sand to make the glass want to go down into the Etch Bath liquid. Definitely wear plastic gloves, as you will have to hold the glass in the bath for 15 to 20 minutes. All in all, this is going to be a labor of love, as this is not going to be a fast project.
