The Science Behind the Sparkle: Understanding Dichroic Glass
So, what is dichroic glass, exactly? The name itself comes from the Greek words "di," meaning two, and "chroma," meaning color. This hints at the core property of dichroic glass: it exhibits two distinct colors depending on the lighting conditions and the angle from which it's viewed.
But it's more than just colorful glass. Dichroic glass is created through a high-tech process called thin-film deposition. Here's the breakdown:
- The Base Glass: This is the foundation. Typically, it's a high-quality clear or black glass.
- Thin-Film Deposition: This is where the magic happens. In a vacuum chamber, various metal oxides (like titanium, chromium, silicon, and aluminum) are vaporized and deposited onto the surface of the glass in extremely thin layers. These layers are often only a few millionths of an inch thick!
- Interference: The different layers of metal oxides have different refractive indices. When light passes through these layers, it's reflected and refracted. The interference of these light waves creates the vibrant, shifting colors we associate with dichroic glass.
- Durability: After the deposition process, the coating is relatively fragile. Therefore, dichroic glass is often fused or laminated to another piece of glass for protection.
Think of it like a soap bubble. The iridescent colors you see on a bubble are caused by a similar phenomenon: the interference of light waves reflecting off the thin film of soapy water. Dichroic glass simply harnesses this principle in a more controlled and permanent way.

What to Look For When Buying Dichroic Glass
Not all dichroic glass is created equal. Here are some key factors to consider when purchasing dichroic glass:
- Manufacturer: Look for reputable manufacturers like CBS (Coatings By Sandberg), which are known for their quality and consistency.
- Color: Dichroic glass comes in a wide range of colors, from vibrant blues and greens to rich reds and golds. Consider the colors that will best complement your project. Some manufacturers offer color charts to help you choose.
- Texture: Dichroic glass can have different textures, such as smooth, patterned, or textured. Consider the texture that will best suit your design.
- Coefficient of Expansion (COE): This is crucial if you plan to fuse the dichroic glass with other types of glass. Make sure the COE of the dichroic glass is compatible with the COE of the other glass. Common COEs are 90, 96, and 104. Using incompatible COEs can lead to cracking during the cooling process.
- Size and Shape: Dichroic glass is available in a variety of sizes and shapes, from small cabochons to large sheets. Choose the size and shape that is most convenient for your project.
- Price: Dichroic glass can be expensive, especially for larger pieces or more complex designs. Set a budget and compare prices from different suppliers.
Where to Buy Dichroic Glass:
- Online Retailers: Amazon, Etsy, and specialized glass art supply stores are great places to find a wide selection of dichroic glass.
- Local Glass Art Supply Stores: These stores often offer a more personalized shopping experience and expert advice.
- Glass Art Shows and Festivals: These events are a great way to meet artists and suppliers and find unique pieces of dichroic glass.

Pro-Tips for Working with Dichroic Glass
Working with dichroic glass can be a bit tricky, but with these pro-tips, you'll be creating stunning pieces in no time:
- Handle with Care: Dichroic coatings can be delicate, so handle the glass with care to avoid scratching or damaging the coating.
- Clean the Glass: Before fusing or laminating, clean the dichroic glass with a mild detergent and water to remove any fingerprints or oils.
- Proper Firing Schedule: When fusing dichroic glass, use a firing schedule that is appropriate for the type of glass you are using. Consult the manufacturer's recommendations for the optimal firing temperature and hold times.
- Test Pieces: Before working on a large project, create some test pieces to experiment with different colors, textures, and firing schedules.
- Layering: Experiment with layering different pieces of dichroic glass to create unique and complex effects.
- Cold Working: After fusing, you can use cold working techniques, such as grinding, polishing, and sandblasting, to further refine your piece.
- Avoid Over-Firing: Over-firing dichroic glass can cause the coating to burn off or become dull.

Frequently Asked Questions (FAQ)
-
Is dichroic glass the same as iridescent glass?
While both types of glass exhibit shimmering, colorful effects, they are created differently. Dichroic glass uses thin-film deposition of metal oxides, while iridescent glass typically uses a surface spray or coating that is less durable.
-
Can I cut dichroic glass?
Yes, you can cut dichroic glass using standard glass cutting tools, such as a glass cutter and running pliers. However, be careful not to scratch the coating.
-
How do I clean dichroic glass?
Clean dichroic glass with a mild detergent and water. Avoid using harsh chemicals or abrasive cleaners, as they can damage the coating.
-
Can I use dichroic glass in a microwave kiln?
Yes, you can use dichroic glass in a microwave kiln, but be sure to follow the manufacturer's instructions for the kiln and the glass. Microwave kilns can be a convenient way to fuse small pieces of dichroic glass.
-
Will the colors of dichroic glass fade over time?
If properly cared for, the colors of dichroic glass should not fade over time. However, exposure to harsh chemicals or prolonged exposure to sunlight can potentially damage the coating.
-
What is "96 COE" dichroic glass?
96 COE refers to the Coefficient of Expansion. This number indicates how much the glass will expand when heated. Using glass with different COEs in the same project can lead to cracking. 96 COE is a common type of fusing glass.
