Crystal

What it is

Crystal is a transparent, glass-like material known for its brilliance and clarity. It is often used in the production of glassware, decorative objects and craft art. Crystal is created by adding lead oxide to glass, which gives it a higher refractive index and thus a more light-reflective surface. This has made crystal a popular choice for everything from fine glassware and vases to jewellery and works of art.

Brief history

The use of crystal dates back to antiquity, but it was not until the 1700s that crystal as we know it today was developed in Europe. In England, lead crystal was produced and quickly gained status as a luxury material. In Norway, crystal became a significant part of craft art throughout the 1800s, particularly with the production of crystal glass from well-known factories such as Hadeland Glassverk and Magnor Glassverk. These factories have helped preserve the traditions and techniques of crystal production in Norway.

How to recognise/identify

To recognise genuine crystal, look for a clear, light-reflective surface, often with prismatic effects when light strikes it. Genuine crystal will also feel heavier compared to ordinary glass, due to its lead content. Many crystal objects also have more detailed cutting and decoration. In addition, one can find marks or signatures from well-known manufacturers that can confirm the origin and quality of the piece.

Collector's value/interest

Crystal has high collector's value, especially pieces from well-known manufacturers or with historical significance. Collectors are often interested in specific styles, such as Art Deco or Art Nouveau, as well as unique shapes or limited editions. The condition of the item, including any wear or repairs, will also affect its value. In addition, crystal items are popular as gift items and decorations, making them sought-after collectibles in both antiques markets and modern design circles.
