Glass Etching
Glass etching
Among glass processing techniques, glass etching is a special design method that enables the roughening of a piece of glass in a certain perimeter for the creation of a model; the resulting image is more like a frosted picture created on a clear glass surface. Moreover, if a thicker type of glass needs some sort of carving, etching is also possible so that a deeper, somehow shaded model is created.
The most common type of glass etching is the sandblast or abrasive model since one can achieve a wide range of aesthetic effects by the use of such methods. The present-day popularity of glass etching has a twenty-year history in design ever since the first architectural applications of the technique came to people's attention. In time, glass etching has little by little extended to interior decorations, gift crafting, the design of glass awards and so on.
Prices for glass etching are pretty high since there is a huge demand for etched objects and the number of professional etchers is still low to answer all the orders. Hence, for anyone who's got the skill at glass work, etching could be a real gold mine. Many people actually start glass etching as a hobby, since it requires minimum investment in both training and equipment. Who knows? Maybe, a small profitable business could grow from a mere enjoyable pass-time.
There are a few very simple principles that govern abrasive glass etching: first and foremost, the frosted look is given by the contact of the glass with small particles of abrasive material that chip the surface, and the process is usually carried on under pressure. And secondly, the design is achieved by exposing only certain glass parts to the abrasive blast, while covering the others. This are the only two general rules of glass etching.
The challenge of glass etching comes when you have to choose the right type of equipment, the perfect abrasive and the correct blasting pressure for the design you want to achieve. Even for amateurs who try glass etching as a hobby, some kind of training is required so as to enable one to perform the etching operation in proper conditions.
There are all sorts of seminars and workshop on glass etching, some of them are available online, some others are organized by special crafts organizations interested in the formation of qualified personnel for the etching job. Glassware manufacturers are the first to implement etching techniques, and they are the ones to offer the most advantageous opportunities for glass etchers too.
