Product of art work
At the beginning of the production, there is a need to produce a technical drawing first. The drawing is provided with exact information about the height, volume, top rim diameter, stem thickness, footplate diameter, the widest diameter in general and thickness of the walls. Based on this drawing a paper pattern gets created, which later serves as a model for a mold-maker.
A wast majority of all the molds which are made from wood, mostly beech wood. To be able to make a good mold, you need your wood to be solid and sucked up by water. To make the wood sucked up, we put beech trunks into a lake. Only when the trunks touch the bottom of the lake, we are sure that they are ready to be processed. The wet trunks are then taken out of the water and sliced into big pieces. A raw block of wood is then fixed to a turning lathe. Later is carved out by some very sharp chisels. At this point, it is fair to say that carving work is not only very demanding for precision, but also very dangerous.
During a handmade production in the melting house, glass gets taken out of a furnace by metal pipes. At first, a glass maker takes a piece of glass and shapes it into a round ball by using a wooden tool. Then the glass maker goes to a place above a small tub filled with water, where the wooden mold is sunk. Once the cup of the glass is made, the pipe is then handed over to another glass maker, who then uses a piece of hot glass to produce a stem of the glass by using a metal tool with pins. The last glass maker within the team then creates the footplate. A finished glass then leaves the working place on a transport line, headed for the cooling room, where it spends the next two hours to cool down. The production of one single glass typically requires a team of 5 glass makers and one other assistant. However, sometimes when a more complicated piece of glass is made, there is a need for a team of 7 or more glass makers.
Cutting & Polishing
After a glass comes out of the cooling furnace, we need to first separate an actual drinking glass from a cap that holds a glass to a pipe. In this first step, we need to make a cut on the surface of a drinking glass by a metal knife. A glass is then placed on fire, where it breaks exactly at the line that we made just seconds before. After we separate a cap, we need to polish the rim of a drinking glass on a grinding wheel. The grinding is done manually on a horizontally placed grinding machine. However, even after the grinding process is complete, a glass is still sharp. Therefore we need to take a drinking glass through a washing machine and then take it to a fire polishing machine. At this position, the rim of a glass is rounded by fire up to a point, where there is no longer a sharp edge neither on the inside nor on the outside of a drinking glass. Only now we are ready for process of individually hand-cutting and polishing each of the glass. After we finish the processing of a glass, we need to carefully examine it at quality control, then we pack it and place it into our warehouse, where is waits for dispatch to be ready to reach final destination.
