There are a few ways to make these. I chose etching because I am going to use them on drinking glasses. The alternative would be to use frosted pearl spray paint. The spray paint is much faster but it also has lead in it so, if you plan on using your glassware to drink or eat from then I suggest you take my route as well.
Things You Will Need:
Disposable paint brushes
Stretch a few rubber bands around your glass. I stretched mine unevenly for a neat effect.
PUT YOUR GLOVES ON and dip your paintbrush in the acid and apply several layers to your glassware. Let it sit for a while. Somewhere between 20 minutes and half an hour seemed to work for me.
Rise your glass thoroughly and dry. The etching will slowly start to appear as the glass dries.
There you have it. Frosted glasses. A great addition to your kitchen!
