Glassware Mfg. – NOCDescription
Code 4114 applies to employers engaged in manufacturing glassware utilizing a mechanical process wherein blowing is done by compressed air on specialized forming machines. Raw materials such as silica sand, lime, crushed glass, soda ash, borax, phosphate, antimony oxide, silica fluorides and arsenic trioxide are purchased from outside suppliers. These raw materials are placed into a furnace and brought to a specific consistency, then placed into molds which form the shape of the product being fabricated. Compressed air is used to automatically blow the product to shape. The product then passes through a tempering furnace. The application of coloring agents and further tempering are additional operations that may be performed. Once the glass product is cooled, it is inspected, wrapped securely and packed.
