The element of most our light fittings is hand-blown three-plied opal glass. The procedure of melting and hand-processing of glass metal causes small imperfections, changes in colours, shapes and strength of the glass. Then each glass shade is the original piece of master-glassmaker´s hand-work. So we cannot expect the same exactness as it is made by the automatic machine. Slight defects, occasional bubbles only confirm the hand-made craft processing of glass metal.
