What is Chemical Etching and How Do People Do It?
Etched glass is a common sight in today’s world, and it adds flair and a touch of elegance to many otherwise mundane pieces of glass. Though few give it much thought, there are actually two very distinct and different ways of producing etched glass, both methods differ in cost and also the final look.
Before getting into the methods, it is necessary to understand the actual process of etching a glass surface. Etching is the process of removing small amounts of a surface of a material to imprint designs. This is done in a controlled manner, to create often detailed and beautiful patterns and designs. The widespread method of glass etching is sandblasting, which required covering a “negative” of the design desired onto a glass surface. To clarify, this is sort of like putting up tape on the areas you don’t want painted when spray painting. The same idea is applied to the glass, and then specialized equipment is used to bombard the glass with sand, which grinds away at the glass where it is not covered and creates a frosted effect.
The more modern method is named “high definition chemical etching”. Instead of using clunky equipment to bombard the surface of the glass with small particles of rock, this process uses chemicals to delicately remove a small amount of material from the surface of the glass. This results in much more fine results, and also opens up the possibility of more depth and shading, as sandblasted etchings are all a uniform frosted white color.
The two methods are very distinctive and produce extremely different results. While sandblasting is better for general designs and large area work, high definition etching is much more tasteful. Not only is it more pleasing to touch, unlike sandblasted glass, it results in much more detailed work.
When deciding upon custom work, high definition etching is definitely the best call. When speaking of custom glass etching a beneficial thing to know is that chemical etching is generally cheaper than sandblasting, partially explained by the fact that it doesn’t require complex and costly equipment. However, a great deal of work or skill goes into its production, as chemical etching is a precise and precarious process, which demands real skill. Pretty much in the etching business there is no such thing as a redo.
Etched glass is a great way to add some class to any glass door, window, table, etc. Etched mirrors can add a classy accent to any home decor furthermore. Each high definition etched mirror also has the amazing ability to stay reflective, even where they’ve been etched. This is not so with sandblasted mirrors, as they look a frosty color in the sections that they’ve been etched. This leaves open possibilities for some very elegant and tasteful glass.
