History of Glass Grinding
First horizontal Grinding benches were used already in the 7th Century BC for processing Glass type objects. The objects found during excavation were partially traces of ground rings.When a work piece is chucked in a lathe-type device or clamped on a turntable and a wood is centered, a pattern develops accordingly. Always two persons were required for processing as per this method.One persons works on the work piece with the tool,and the other turns a type of crank. At first such glass pieces were discovered during excavations from Mesopotamia so far. It is believed that this handicraft had spread from there to Mediterranean.
