How are Swarovski crystals different from plain glass?
According to Swarovski, Many Swarovski lovers believe that the raw material used in the manufacture of our crystal objects occurs naturally. Nothing could be further from the truth. Swarovski crystal is made at the factory in Wattens using basic formulae perfected by Daniel Swarovski and his three sons in the earlier part of last century. Swarovski crystal is fired using a combination of natural minerals and quartz sand, and then cooled slowly to avoid stress and inclusions.
