The extraordinary quality of the material is already in the name, for a superiority assured by its special chemical composition. It is the single elements that determine the quality level: the presence of barium oxide combined with potassium oxide ensures absolute purity, brilliance and sonority.
Superiori in brilliance ande trasnsparency.
It has the same aesthetic values as crystal, but is lighter and more practical. The exceptional brilliance is due to a perfect balance between the refractive index and density of the glass.
