Not only does it fulfil a practical purpose but there are so many other ways in which glass enriches our life. It is brilliant, it reflects and refracts light and has a satisfying sound when glasses are clinked.Still further, specific glass shapes and a high quality glass surface, through the use of pure raw materials, enhance the aromas and taste of beverages. ♥BRILLIANT CLARITY  Spiegelau glasses are extremely transparent, clear and brilliant. But how can these benefits be achieved?To start with, it depends to a great extent on the type of glass used and the characteristics of the ingredients.Glass consists of sand, lime (an alkaline earth oxide), Sodium or Potassium oxides (Alkali oxide) and a certain amount of cullet of the same composition. These ingredients will be melted at approx. 1500°C and in later steps formed to the desired product.Depending on the composition, there are four major categories of glass: Borosilicate, Glass, Crystal glass, and Lead crystal. ♥QUALITY MADE IN GERMANY  To ensure an enduring quality standard, Spiegelau has a strong commitment to its production sites in Germany.
