Dichroic Glass Jewellery: NASA Technology Meets Art
Share
Before it ever became jewellery, dichroic glass was created for space.
Originally developed for high-performance optical applications — including visor and filter technology explored in NASA-led aerospace research — dichroic coatings were designed to control intense light. Scientists used ultra-thin metallic layers to reflect certain wavelengths while allowing others to pass through, protecting eyes and instruments in extreme environments.
It was precise. Technical. Entirely functional.
And yet, when light moved across this glass, something unexpected happened.
The surface shimmered. Colours shifted. Depth appeared where there had been none. What began as a scientific solution quietly revealed a different kind of potential — one that artists and glassmakers would later recognise immediately.
This is where the story of dichroic glass jewellery begins.
When Science Met Art
When artists first encountered dichroic glass, they saw more than technology. They saw movement, colour, and possibility. Unlike traditional coloured glass, this material didn’t stay still. It responded to light. It changed with angle. It felt alive.
What scientists had engineered to control light, artists began to use to celebrate it.
Through cutting, layering, and kiln-firing the glass by hand, dichroic glass was transformed from an industrial material into something intimate and expressive — jewellery that reveals different colours as you move, turning light itself into part of the design.
What Makes Dichroic Glass So Unique?
Dichroic glass is created by bonding microscopic layers of metal oxides — such as titanium and silicon — onto clear glass in a high-vacuum chamber. These layers interact directly with light, reflecting some wavelengths while allowing others to pass through.
The word dichroic means “two colours”, but modern dichroic glass often reveals many colours at once. A single piece might glow with blues and greens in daylight, then shift to warmer golds or flashes of pink under artificial light.
This isn’t a surface coating or paint that fades. The colour exists because of physics — making it stable, long-lasting, and endlessly shifting.
From Experimentation to Jewellery Collections
Much of my jewellery collection was further developed and refined during a 10-month residency at Orleans House Gallery, where I spent extended time experimenting with dichroic glass and kiln-fused techniques.
Working with this material is as much about intuition as it is about skill. Small changes in temperature, layering, or placement can dramatically alter the final result. That unpredictability is part of the beauty.
No two pieces ever turn out exactly the same — even when they begin with the same idea. Each one carries subtle differences in colour, texture, and light, shaped by the process itself.
Why Dichroic Glass Changes Colour
The colour-shifting effect of dichroic glass comes from a phenomenon known as thin-film interference — the same effect seen in soap bubbles and butterfly wings.
As light hits the glass:
- some wavelengths are reflected
- others pass through
- colours shift depending on angle, movement, and lighting
This means a piece of dichroic glass jewellery can look entirely different indoors and outdoors, in morning light or evening glow. It changes as you do.
Jewellery That Feels Personal
People are often drawn to dichroic glass jewellery instinctively. They don’t always choose it because of trends — they choose it because of how a piece feels.
A single pendant or pair of earrings may reveal calm blues one moment, warmer golds the next. That constant transformation makes the jewellery feel personal, expressive, and quietly alive — almost as if it adapts to its wearer.
From Space Technology to Wearable Light
There’s something quietly magical about wearing a material that began its life in aerospace research and now rests against the skin.
Dichroic glass jewellery carries a rare combination:
- the precision of science
- the intuition of handcraft
- and the poetry of light in motion
Each piece holds a story that stretches from laboratories and NASA research environments to the studio, the kiln, and finally to you.
To wear dichroic glass is to wear light itself — shaped by science, refined by hand, and brought to life through movement.
