Etching Colored Glass
Etching colored glass can be tricky if you do not understand which method you need to use. This article will help you determine how to tell the difference between real colored glass that can be etched with Etch Cream and which kinds of colored glass have to be Sand Etched.
The pictures shown here are examples of projects on real glass, topically colored glass and sand etched sandwich glass:Real colored glass....-Etch Cream Project: Summer Fun Cordials Painted coated glass...-Sand Etched project: Easter 6pc Tealights Layered color glass...Sand Etch project: Western Luncheon Plate
Fact: What makes Etch Cream etch... Etch Cream reacts with the silica properties of the glass. If the etch cream does not make contact directly with the surface of the glass it will not etch. A mere fingerprint can stop Armour Etch from working properly. Colored glass that is painted will not etch.
Fact: What is Sand Etching... Sand Etching is sand blasted by canned propellant and abrasive. When using this method you are roughing up the surface of the glass and removing tiny particles of glass. Sand Etching will etch painted colored glass that will not etch with Etch Cream
True colored Glass:True colored glass is colored all the way thru the glass and typically this includes the bottom. The coloring has been mixed into to the molten glass while it was being formed. The color should be even throughout and you cannot scratch it off with your fingernail.
Multi colored glass glass will also etch (2 or more layers of colored and/or clear glass sandwiched together). These types of glass pieces may have a clear bottom or edge however they are made of real glass. Although they most likely will etch with the cream, sand blasting or sand etching would be a better choice with terrific results. (see: western plate project in Home Decor section)
Some problems with etching true colored glass: Colored glass tends to be harder than clear glass. The results of the etching may not show very well. Black glass and very dark colored glass especially. This became evident when we did the Halloween projects on black glass. The etchings came out well, you just could not see them without enhancement. We did need to use white Rub n Buff to make the etching stand out. This would not have been an issue with sand etching.
Occasionally you will get a piece of true colored glass that has been enhanced with a layer of iridescence, Mother of Pearl or a gilding (metallic gold or silver), these enhancements also create a barrier which will prevent the glass from etching with the Armour Etch cream but itcan be sand etched
Typically colored glass (fake colored glass)Typically colored glass is glass that has been stained, painted, coated or dipped in a transparent coloring to look like real colored glass. Since this process is cheaper and quicker to produce than the real deal, you will find them most frequently in discount departments. So if you find such a piece, examine it carefully and most likely plan on sand etching it.
Some telltale signs of treated or coated colored glass is:
The rim or bottom of the piece is not colored but clearYou can scratch the color off with your fingernail. The color appears uneven, puddled near the top or bottom, spotty or wavy and looks thicker in some spots.
