THE CRAFTS
Glass and crystal are not easy to describe. Its physical structure is neither liquid, solid nor gaseous. Using traditional knowledge in the craft, molten crystal is formed into objects, each with your own personality and unique expression. A large part of Vas Vitreum's collections are manufactured without molds, only with the help of the master's eyes and experience to create the final product.
One high-quality raw material is of utmost importance in the production of world-leading crystal. Therefore, Vas Vitreum uses a specially made crystal mixture with properties such as a high refractive index, which gives superb reflection and great weight. The crystal melts at a temperature of 1400 degrees Celsius, but is then lowered to a working temperature of 1100 degrees.
A lesson in the craft
Every single product from Vas Vitreum is genuinely handmade in family glass cabin in Vadstena. This allows Vas Vitreum to have full control at every step from design to finished product.
THE MATERIAL
All crystal objects begin their life as sand. To produce crystal of the highest quality, the raw materials need to be very clean and almost completely free of iron and other metal oxides. The sand Vas Vitreum uses comes from Belgium and is located at a depth of 50 meters.
MELTING
The sand is mixed with lime, soda and potash, which is then tied together to pelletized form. About 300 kg of pellets are then melted in the large oven at a temperature of 1400 degrees Celsius. The whole process takes 8 hours.
MANUFACTURING
The glass can then be shaped, often with the help of wet newspaper and blown into various objects. A large part of the glassworks Vas Vitreum's collections are made completely freehand without molds, only with the help of the master's experience and craftsmanship, to realize the product.
SOFTENING
All manufactured items must be cooled slowly when they are ready in the cabin. This is done in a softening oven that maintains a temperature of 520 ° C. The cooling process takes from 12 hours to several days, depending on the thickness of the object.
GRINDING
Each object becomes then cold worked and ground in the bottom with at least three steps.

The finished product is signed with Vas Vitreum, article number, color and designer.
