When shopping for crystal engraved awards there are several choices to be made. The first will be the type of crystals to be used. The most well known and admired are leaded crystals. They are highly prized and feature excellent quality. Secondly there are optical crystals. These are lead free and feature high sheen and reflection on their surfaces.
Leaded crystals are made by adding over twenty percent lead oxide to the process. The leaded oxide ensures that the optimum color, weight and hardness will be present in the finished product. This process also enhances the clarity of the crystals when the items are completed.
Optical crystals are lead free and created in large sheets up to three inches thick. They are extremely hard and will cut and bevel perfectly. They also contain a high level of brilliance when polished. While still molten the liquid is subjected to extreme pressure to remove all bubbles and flaws that may occur in processing. These crystals are often used in camera lenses and binoculars because of their flawless quality.
Engraving techniques for these crystals are identical. The most often used is sand blasting. This method consists of using a high pressure tool that shoots particles of sand onto the surface of glass to create the desired design. Most artists who use this technique also use stencils to help prevent errors. Sand etching can turn out very delicate images that highlight the intricacies of the original design. A relative new comer in the field, sand etching has only been around for the past twenty years.
One of the fast disappearing techniques is wheel engraving. This method of etching is very difficult to learn and execute. The artists who have mastered this technique are truly master craftsmen. The most difficult aspect of this method comes from having to move the glass rather than the wheels to create the design. The wheels used are of various sizes to accommodate the arch and depth of the work in progress and must be changed often.
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.
For the frugal shopper laser etching may be the best choice for the crystal engraved awards you need. Technique and materials can make a big difference when making your selections and the size of your order should have bearing when choosing. The wide variety of choices will help to make your selection fit perfectly to your needs.
