Generally, when people think crystal, they think of wine glasses, decanters and cut crystal bowls from such well known names as Waterford Crystal etc.
However at Mullingar Crystal there is not a wine glass or decanter in sight.
Mullingar Crystal use a crystal called Optical Crystal.
Optical/Optic Crystal is 100% Lead Free and extremely hard. It is this hardness that provides the basis for the brilliant cuts and bevels, as well as the ultra high polished surfaces. Each piece of Optic Crystal is hand polished and beveled. Optical /Optic Crystal, as its name suggests is used in binoculars and camera lenses as it is pure, totally clear and represents the ultimate expression of excellence. Optical Crystal is manufactured in large sheets up to 3" thick, and while still molten, is subjected to tremendous pressure to ensure no bubbles, flow lines or other distortions.
Optic Crystal is seen as being the “king” of Crystal in that it can have no imperfections.
Mullingar Crystal also uses black optical crystal for many of the bases of the awards. Black crystal is produced with special additives (Fe2O3, CuO, MnO2, CO2O3) that change the color to black. Black crystal posses almost the same physical qualities as lead free clear optical crystal. However it does not allow light transmission. Black crystal is by far superior in quality to black color glass, it has no bubbles or swirl marks and its surface are perfectly smooth and flawless.
