Class Code: 4111

Per NCCI's Scopes Code Description:

Code 4111 applies to the manufacture of glassware by either a mouth-blowing process or by a semiautomatic blowing process. In some plants both processes are conducted side by side. Crushed glass, lime, silica sand, phosphate, antimony oxide, arsenic trioxide, silica, silica fluorides, borax and soda ash are received from others. The raw materials of predetermined mixture are dumped into mixing tumblers and poured into hopper cars. The batch is fed into a furnace and the molten glass is either formed by the mouth blowing process or hand filled into molds in the shape of the product and then transferred to semiautomatic blowing machines. The products are slow cooled to harden. The application of coloring agents and further tempering are additional operations which may be performed. The products, following inspection, are packaged for shipment. Some of the products that have been classified under Code 4111 are glass tableware such as cups, saucers, plates, glasses; pyroglass bake ware; perfume bottles; candlestick holders; kerosene lamp chimneys; auto headlight lenses; glass radio insulators; and molded glass doorknobs, paperweights and ashtrays.

Refer to Code 4149 for the manufacture of optical goods and electronic chips from quartz.
