Class Code: 4053
Per NCCI's Scopes Code Description:
Code 4053 is applied to insureds engaged in the manufacture of china or tableware pottery such as cups, saucers, plates, soup and serving dishes, cream pitchers and sugar bowls which may be decorated, unglazed or glazed. The classification contemplates mold making, usually from plaster of paris, which is received from others along with clay, sand, decals, paints, glazing compounds and cartons with dividers for packaging. Sand, clay and water are mixed in automatic mixing machines and extruded, forming a column of clay in the desired consistency. The clay is fed to potter’s wheels or automatic molding machines. At the potter’s wheels, craftsmen form the products by hand. The formed greenware is stored on racks for drying in high-heat kilns. Decal work or hand painting is done prior to glazing and the products are again sent through the kilns. The finished items are inspected for defects and then packaged for shipment.
Code 4053 also is applied to insureds engaged in the manufacture of architectural terra-cotta that is used for decorative purposes. Clay, sawdust, straw, coal dust and sand are received from others. The clay is mixed with any one of the other raw materials depending upon the type of terra-cotta tiles desired. This is mixed with water and ground to various finenesses and screened. Some grinders are the wet pan type, while others are the dry grinding type.
After the clay has been properly mixed and compressed in the pug mill or tempering machine, it is molded into the tile size and shape desired, usually in automated equipment. The tiles are stacked on cars, which are conveyed through ovens for drying. The product is then inspected and packaged for shipment.
Etching or “sand carving” is additionally encompassed by Code 4053. The insured engaged in these operations usually purchases stoneware, ceramic, and glassware blanks from others. The etching or “sand carving” involves placing a plastic film character on the piece to be etched and washing it in a mixture of water and soap, which leaves an outline of the film on the piece. The piece is then sandblasted with aluminum oxide to etch in the design. The finished piece is cleaned, inspected, and packed for shipment.
