I have a vinyl cutter and decided I wanted to try glass etching. This stuff works fabulously!My process was to cut my design in adhesive backed vinyl, weed out the parts of the design I wanted to etch, apply clear transfer tape to the front of the design, peel off the backing paper on the vinyl, apply it to the glass I wanted to etch, carefully peel off the transfer tape, apply a thick coat of the Armour Etch Cream using a foam pouncer, wait at least 5 minutes, wash the cream off with running water and then remove the vinyl.Here are some tips to get the best results:1. Make sure the glass is very clean. I wipe it well with rubbing alcohol to ensure there are no oils that would prevent the etching cream from etching evenly.2. Rub the vinyl hard to make sure every edge is completely adhered to the glass. If it isn’t, the cream can bleed under the edges.3. Apply the cream thickly and as evenly as possible. I pounce it on rather than brush it to avoid brush marks in the etch. Make sure it’s so thick that you cannot see through it at all.4. The directions say to leave it on for 5 minutes but longer is fine and makes a deeper, more frosted etch.5. Work on a covered surface and wear gloves. If this cream gets on anything else, it will etch it, too. Remember, this is an acid that is strong enough to etch glass! Also, I suggest working in a well ventilated area. I do it on my front porch.You can etch all sorts of things. Some I have etched are glass tumblers, mugs and steins, glass dinner plates and platters, glass bakeware, mirrors, canisters, jars, bottles and window glass. Etching your name onto platters and bakeware ensures it gets returned to you. Etching names and monograms onto simple glass mugs or plates turns them into fabulous gifts.This is a fairly big bottle of etching cream and even applied thickly, it will etch a lot of glass.
