All the German Made Sapphire Domed Glass Crystals on this page are what some want to call double domed. They mean that the dome of the glass is domed and the that inside is not flat and also has an inner dome. The industry just calls them Domed and when they have a flat bottom they are called Domed Flat Bottom which is not common at all as compared to just domed. Domed Crystals in both Sapphire and Mineral Glass are not made in the same shape and dome found in Plastic Crystals. The shape, and both the inner and outer height is much lower then plastic crystals and if you want to change from a plastic to sapphire is not possible. |
