Dichroic glass is glass with a wafer-thin metal oxide coating that shimmers in different colors depending on the viewing angle and light. The effect is reminiscent of an oil slick or a beetle's wing – vibrant and iridescent.
How does Dichroic Glass work?
An extremely thin layer of metal oxides is vapor-deposited onto the glass in a complex process. This layer reflects certain light waves and allows others to pass through – depending on the angle. This changes the perceived color when you turn the piece. The name "dichroic" means "two-colored," but it only approximates the variety of effects.
What makes Dichroic Glass so popular?
- Color change – shimmers differently depending on the viewing angle.
- Depth – almost looks as if the glass is glowing from within.
- Unique – every play of light is different.
Dichroic Glass in Glass Art
In lampworking, dichroic glass is used as an accent – for example, as a shimmering dot or as an element in an implosion pattern. Even a small dichroic detail on a bong or pendant creates an elegant, vibrant effect.
Frequently Asked Questions
Why does dichroic glass change color?
Because of the thin metal oxide layer, which reflects light differently depending on the angle.
Is the effect painted on?
No, it's a vapor-deposited coating – nothing flakes off.
Does dichroic glass affect functionality?
No, it's purely optical – the bong works as usual.
