Hand-cut glasses, in which the cut is made into the raw material of coloured lead crystal, which is created by combining a layer of clear crystal together with a layer of coloured crystal. It is this outer coloured layer that is cut or burnished to create the intended decor. This manufacturing process is the pinnacle of glassmaking skill. More
A handmade product made of colored crystal with 24% PbO content, which is created by combining a layer of clear crystal together with a layer of colored crystal at temperatures around 800 °C. This manufacturing process is at the peak of handmade capabilities and only the best and most skilled glassmakers can produce it. The difficulty of production is reflected in the fact that no method has yet been invented that allows for machine production. In this product, traditional work has been preserved to this day. Younger generations of glassmakers learn the skills of glassmaking from older glassmakers.
The basic raw materials used in glassmaking are glass sand, potash and limestone. Glass shards are also added to the glass cullet. The typical colours of the crystal being taken over are created by adding metal oxide admixtures to the furnace during the melting process. The current colour palette includes ruby, blue, violet, green and cyan. Quite exceptionally, black is also melted, but this is only suitable for certain shapes and decors. Each product must successfully pass through several quality control stages following each individual process. The acceptance process takes place at a temperature of around 800°C, when a flask of white crystal, which forms the base of the product, is inserted into a pre-shaped coloured funnel. The process continues with the moulding in a moist wooden mould, into which the glassmaker inserts the flask, which is then blown into its basic shape. The wooden moulds are changed regularly as they are in constant contact with the hot mass. By grinding the glass to different depths, using a natural or synthetic wheel, the cutter achieves the desired shape and design of each product. The polishing is the final touch to the entire production process. Here, each product is completely immersed in the polishing bath. This gives the product a shine that further enhances its beauty and splendour.
