Crystal engraved awards can lead the consumer to a multitude of choice selections to be made. The crystals themselves have two distinct classes that consist of leaded or optical types. Leaded crystals are the traditional pieces that we see in high end shops. Optical crystals are made one hundred percent lead free and present with a high luster surface finish.
Leaded crystals are created by adding lead oxide to the glass formula. The lead component is generally around twenty four percent for optimum color, weight and hardness. This number also ensures the clarity of the glass will remain at optimum levels. They are highly valued and many become family treasures that are passed down for generations.
The optical crystals are created with absolutely no lead added in sheets approximately three inches thick. Known for the hardness and brilliance these crystals contain they are often used to make camera lenses and binoculars. The hardness also ensures perfection while cutting and beveling. As a molten sheet they receive a highly pressurized treatment to remove all bubbles that may occur in processing or other flaws that may be present.
There are four separate styles of etching that can be done on both types of crystal. The most well known and widely used is sand etching. This technique involves directing thousands of sand particles at the stenciled glass under very high pressure. The resulting image is a concise and delicate image that results from smooth, precision cuts. This has been a favored method by master craftsmen for over twenty years.
Wheel engraving is another form of glass etching. This type of cutting is very labor intensive and demands high levels of training for the artist. It is the most difficult technique to master and is confined to small scale projects that inhabit the high-end markets. The artists who master this technique are truly dedicated to their trade. The wheels used are stationary and the glass is moved making this a most difficult task to learn.
Another technique that is disappearing is chemical, or acid, etching. The fumes from the acid used have proven to be very dangerous to the health of workers who use it. The end result of this technique is thought by many to be far more satisfactory to the trained and untrained eye. The edges are softer and the finish has a hazy matte gloss that cannot be accomplished otherwise. Few craftsmen use this method of etching today.
Laser engraving is the newest technique to be used. This system takes less time than traditional etching and works exceptionally well on optical crystals. The leaded glasses tend to end up with microscopic cracks in the etched areas that lasers create. Lasers have uniqueness in that they can create images inside a block of glass without disturbing the outer surface of the item. Some of the master craftsmen feel that the laser etching method is a shortcut and not of the same quality as the traditional methods.
There are several techniques that can be used to create crystal engraved awards. The method you choose may also determine the amount you will spend on it. The two most used styles are also most likely the two most affordable for consumers.
