Everything you absolutely didn't need to know about Alexandrite glass.
First of all it's actually Alexandrit™ and yes, it's a trade name.
As many of you surely know, Alexandrite glass has a unique shade of purple and is one of several types of dichroic glass, meaning it sends off light in different wave lengths depending on the type of light hitting it. It appears purple when looked at under most light sources, but turns light blue under fluorescent light (sometimes improperly called neon light).
This property is granted by neodimium, a chemical which started being used in glass manufacturing in the late 1920's. Neodimium glass is in fact it's other name. But why is it commonly called Alexandrite?
We'll have to take you back another 100 years to early 1830s Russia. In the Ural mountains a new gemstone, previously unknown, was discovered: green under sunlight and red in artificial light. The name Alexandrite was chosen as a homage to Czar Alexander II (then heir to the throne). Deposits of Alexandrite gemstone have since been discovered in Brazil, East Africa and Sri Lanka but it is still very rare and valuable today.
Back to early XX century: in 1927 famed Bohemian crystal maker Moser commissioned a research to a group of German chemists who over the span of two years helped the brand bring to market a new kind of neodimium-infused glass with the property of changing color from purple to blue.
Some marketing genius at Moser had the idea to trademark the name Alexanrit as it was already associated with a very luxurious color changing material (the Alexandrite gemstone of coursee).
The first range ever of Alexandrite glass items was presented by Moser at the 1929 Leipzig Spring fair.
Many brands followed suit in the years to follow.
In France and Italy Neodimium glass became popular especially in the 1960s and 70s.
At All'Origine we select both pressed and mouth blown pieces and since we are unable to lie: the second picture made with Ai 😭😭. We did not have an appropriate fluorescent light when we shot this picture about 6 months ago. But now we have it. Next time our photographer Luciano Paselli is here we will take new pictures, I promise.
