Raw Materials
To produce a glass article (whether bottle, jar or tableware) we mix the following raw materials: mainly sand, soda ash, limestone and several other ingredients. Cullet, which is actually broken glass, is added to this mixture as well.
Furnace
The furnace melts the mixture of raw materials and cullet in a temperature around 1600οC; molten glass is soft, and almost liquid, thus very flexible.
Forming
The molten glass is cut into uniform gobs, and then sent to a forming machine that forces the molten gobs into the desired mould shape.
Annealing Lehr
The shaped glass leaves the forming machines, and enters a cooling plate, so that it cools off to a solid form.
Quality Inspection Machines
Manufactured glass articles go through a series of quality control instruments and personnel, that test them for flows or technical non-conformities.
Packaging
Glass products are then packaged and stored or shipped to the end-user.
