|Glass etching is a great way to create frosted images into glass nearly anyway that you want using artistic designs. It is looked at as an elegant way to spice up your glass whether on the surface or for deeper etchings which I will talk about in a bit later. First, you can do this by using acid or abrasive particles to rough up the glass. Each little chip or acidic eating of the glass causes it to become frosted. After the glass is etched, the light is partially refracted causing its whitish frosted look.
Some methods look better than others because the light gets refracted more, making it easier to notice the design. The sandblasting method is one of the better ways to etch designs and can also be used to carve into the glass which is called sandcarving. Through sandblasting you can achieve other techniques such as shading which is similar to airbrushing.
Here is a list of some of the techniques you can do with sandblasting:
-Glass Shading allows you to create gray-scale etchings permanently on the glass with varying shades of darker and lighter effects.
Surface Etching basically lightly etches the surface with one thickness all the way around.
Sandcarving etches deep into the glass and can be mixed with different depths to create a 3 dimensional appearance. It is best looked at from the opposite side to see the beautiful dimensional art.
Those are some of the known ways to artistically etch a design with sandblasting methods. Now I will discuss more about the acid and cream methods.
Acid and cream etching is a process of smearing or brushing a chemical substance which eats at the glass. The cream is a acid but of a lesser potency than regular acid etching processes. It is primarily used for a lot of craft applications and acid etching is typically used for more experience or trained people. It can be very dangerous if you don’t take the safety precautions seriously.
