Dichroic Glass is a multi layer coating placed on glass by using a highly technical vacuum deposition process. Quartz Crystal and Metal Oxides are Vaporized with an electron beam gun in an airless vacuum chamber and the vapor then floats upward and attaches then condenses on the surface of the glass in the form of a crystal structure. Our colors have as many as 30 layers of these materials yet the thickness of the total coating is approximately 35 millionths of an inch. The coating that is created is very similar to a gemstone and by careful control in thickness, different colors are obtained. Thus, all our coatings are created using the same exact materials. Originally created for the Aerospace industry, Dichroic Glass is now made available to the artist community through Coatings By Sandberg, Inc. CBS Dichroic Glass is specifically designed to be hotworked in any way but can also be used in its raw form. The main characteristic of Dichroic Glass is that it has a transmitted color and a completely different reflective color. Furthermore, these two colors shift depending on angle of view. With the play of light together with its vibrant color, Dichroic Glass is a prime tool used to add interest to any piece of work or project. With over 45 Colors of Dichroic Coatings available to be placed on “any” substrate (ie glass), artists have unlimited freedom of expression.
dichroic glass sheet pricing
We do post pricing for our packaged products and sample/starter packs online. However, we are sorry, but we cannot post our pricing for sheet glass on our web site. We operate our pricing structure on estimated annual volume. Thus, pricing can be different for everyone. On average, a low volume user of Dichroic Glass, can expect to pay between $160 and $190 Retail for a standard color on a 19" diameter sheet of glass. Please call us to discuss pricing any further.
You can now signup for a wholesale account online by clicking on the 'Wholesale Login' button at the top of all of the shop online pages or by calling our offices for more information.
STANDARD VERSUS PREMIUM COLORS
Standard and Premium colors refer to pricing only. Our premium colors have twice as many layers than our standard colors and thus, take more time to produce. Therefore, premium colors are a little more expensive. Our Specialty Colors and Patterns are "Standard" as far as pricing, but anything that requires tooling to create (ie: patterns) are $15 Dollars extra.. For example: a Brick Pattern would be a Standard Color Price plus $15 Dollars tooling charge.
Dichroic COATED FRIT VERSUS BROKEN SHEETS
The Dichroic Coated Frit that we currently offer in 90 and 96 COE is frit that we have purchased specifically to be coated with a Dichroic Coating. This product is not broken up sheets of glass, but actually coated frit. After extensive research CBS has designed a proprietary process that allows the frit to be coated on approximately 80 Percent of the surface area of the glass. Thus, one 8-ounce jar of Dichroic Coated Frit has the equivalent coated surface area of more than one full sheet of flat glass. This ratio of glass to Dichroic Coating is unmatched to any other product available on the market today. Due to this high ratio of Coating versus Glass, the Dichroic Frit responds very differently under heating/hotworking conditions,… a must try for artists looking for a fresh or different look to their work.
STAINED GLASS APPLICATIONS
Though most of our customers are hotworking our glass in one form or another, we do have customers that use our glass for Stained Glass Windows. Due to the nature of Transmission Color versus Reflection Color, one must chose colors carefully when a stained glass pattern includes an object or scenery. Other applications include: Glass Block Walls, Skylights, Outdoor Sculptures, and more. We also coat Bevel Clusters for Stained Glass applications.
The tile industry has recently made a strong presence in the use of Dichroic Glass. Some problems have been associated with the variance of colors. Large tile manufacturers that require a large lot of the same exact color have difficulties, since the coatings vary in color slightly, from one sheet to another. Nevertheless, accent tiles, mosaics, patterns, and abstract tiles are very popular and are even currently being sold in large home and garden stores such as Home Depot Expo.
GLASS BLOWERS & LAMP WORKERS
Our growing customer base of glass blowers and lamp workers is immense. Remember that CBS Dichroic is only the Coating, and the Glass is just a vehicle to place the CBS coating onto. Thus, we can coat any type of glass. For your convenience, CBS carries a large variety of glass on hand ready to coat to your specifications: 90 & 96 Co-efficient, Bullseye, Uroboros, Spectrum, Pyrex, Moretti, Rods, Float and more. WE’LL EVEN COAT YOUR GLASS!!
There is an ever growing demand for the use of Dichroic Glass in architecture. Its resilience to weather and never-fading colors are prime material to enhance office buildings, custom homes, walkways, fountains, skylights, walls, lighting fixtures and more.
other dichroic applications
CBS Dichroic is so versatile that it is being used in large architectural applications, stained glass type installations, tile production, and even in construction. Its resilience to weather and never-fading colors are prime material to enhance office buildings, custom homes, walkways, fountains, skylights, walls, lighting fixtures and more. Other applications of CBS Dichroic Glass is left up to the imagination of you the artist community.
DICHROIC GLASS IN OTHER INDUSTRIES
Dichroic Glass was originally created for the Aerospace industry for Satellite mirrors, but it now has many technical uses including: Lighting, Fiber Optics, Infrared Lazers, Motion Picture Equipment, Sun Glasses, and more.
Please refer to the manufacture of the glass that you are using for recommended fusing schedules. The Dichroic Coating does not change the COE or integrity of the glass in any way.
CUTTING DICHROIC GLASS
The Dichroic Coating does not affect the integrity of the glass in any way. We only recommend that you cut/score the glass on the "UNCOATED" side of the glass substrate. This will produce a much smother and cleaner break.
CBS, Inc. is a family owned corporation run by Gerald (Jerry) Sandberg (CEO), Nona Sandberg (President), and Howard Sandberg (CFO). The company has been in business since 1996, but Jerry Sandberg, its founder, has been producing and supplying Dichroic glass to the art community for well over 25 years. CBS was created in response to the artist community that encouraged Jerry to develop a consistent and reliable outlet for the manufacture and marketing of fine quality Dichroic Glass. Thus, Jerry is the original creator of the vibrant and effective colors that CBS presently manufactures. In fact, we are so confident in what we manufacture that CBS guarantees its product. If you are not completely satisfied with CBS glass, return it and we will replace it.
Put our glass in the fire
CBS Dichroic Coatings are specifically designed to be hot worked. We coat our glass for use in: Glass Blowing, Flameworking, Fusing, Slumping, Beadmaking, and any other technique that involves the manipulation of glass with extreme heat.
our dichroic glass does not burn out!
Many artists have experimented with Dichroic Glass before, but have become disappointed with its characteristics under extreme heating conditions. Some Pyrex workers had actually stopped using Dichroic glass because they claimed it disappeared or became white when hotworked. NOT CBS DICHROIC!! We have supplied several renowned artists with samples of CBS Dichroic Glass and instructed them to “Burn-it-out.” The only damage that was noted to the CBS coating under the most severe conditions was a slight residue formed on the edges. Thus our colors stayed vibrant, our coating remained intact, and the experiment was a true measure of CBS’s solid quality product. We invite all artists to try CBS Dichroic, especially if you have been disappointed in the past with lower quality Dichroic Glass.
Dichroic Glass SCRATCHING
The quality Dichroic surface is stronger than the glass that it has been placed onto. The final layer that we adhere to the glass is Quartz Crystal (This material is almost as strong as an actual diamond). But, because it is so extremely thin, if something can scratch the glass, it will usually also scratch the coating. We do not recommend using abrasives such as steel wool, etc. Also, when grinding the edge of the glass, the coating will chip off along with the glass that is also being chipped off. We recommend using a fine grit grinding wheel when trying to keep chipping to a minimum.
CUSTOM dichroic COATINGS
WE WILL COAT YOUR FINAL PIECE OF WORK. CBS has custom coated many pieces of art that have resulted in a one of a kind look. We have custom coated: Rondell Bowls, Sculptures, Beads, Pyrex Tubing/Rods, Stringers, Glass Block, Bevels, Prisms, Buttons, Jewels, Crystals, and more. Please feel free to call us directly to discuss your personal options.
WHY ARE THE SHEETS ROUND
Our sheets are round because of the process. The sheets must rotate during the coating process to achieve a constant uniform color across the surface of the sheet. This is a way to maximize the surface area that is being coated in our chamber at any one given time. We can coat square sheets, but they would be smaller and require different tooling, thus creating greater expense for less coated glass.
can we coat squares?
We have the ability to coat many different shapes and sizes of glass, including 3 dimensional pieces such as sculptures, bowls, tubing, rods, glass block, crystals, buttons, beads, and more. We can coat square sheets that fit within the same area as our 19" or 24" diameter glass. Thus, the largest square we can presently coat is a 17" inch square.
TRANSMISSION VERSUS REFLECTION
The "Transmitted Color" is the color you see in a clear piece of glass when you can actually see through the glass. The "Reflected Color" is the color you see in a clear or opaque piece of glass when the light bounces off of the surface of the glass. Most of our colors are listed with its Transmission Colors then its Reflections Color. For example "Blue/Gold" will be Blue in transmission and Gold in reflection. If we coated a black/opaque sheet with Blue/Gold, you would only see its reflection of Gold (Yet, it is still called Blue/Gold).
MATERIALS USED FOR dichroic COATING
We melt Quartz Crystal and Metal Oxides to produce our quality coatings. Only the highest and purest quality materials are used for our processes. These materials are vaporized with an electron beam gun, and the vapor then attaches and condenses onto the surface of the glass, forming a crystal structure comprised of as many as 30 layers.
we have dichroic glass patterns!
Dichroic patterns have become increasingly popular. We currently offer over 18 types of patterns including: Squares, Dots, Marquis, Brick, Honeycomb, Balloons, Boxes, and a variety of Rainbows and other configurations of colors. Unlike an etched or photo resist pattern, ours are completed during the coating process. Therefore each of our patterns have colorful rainbows around each small shape. We are taking an aggressive stand into the research and development in this arena. Please feel free to call us directly to discuss your personal needs.
do you sell quarter sheets?
No. In an effort to motivate our Distributors, we have chosen not to sell quarter sheets.
What are the sheet dimensions?
Dichroic Coated Glass sheets are offered in 19" inch diameter rounds. Depending on the glass manufacturer, the round sheets in most cases, have two flat sides approximately 16" to 17" inches apart. Approximate square inches of a "Full" 19"inch diameter sheet is: 283 square inches. Approximate square inches of a 19" inch diameter sheet with flat sides is: 262 square inches. We also have the ability to coat 24" inch diameter sheets (Please call us for details).
