The pressed and blown glassware industry manufactures products ranging from television tubes, ashtrays, candlesticks, stemware, tobacco jars, and optical lenses to Christmas tree ornaments. Throughout the 1980s and 1990s, the industry maintained a steady level of employment at about 37,000 workers, while the value of shipments rose steadily to reach $5.9 billion by 1997.
In the late 1990s, the industry was made up of 1,528 companies operating more than 1,650 establishments. These companies generated shipments valued at $11.49 billion, up roughly 45 percent from 1992 shipments of $6.89 billion and up nearly 20 percent from shipments of $9.66 billion only two years earlier in 1998.
Establishments primarily engaged in manufacturing hydraulic cement, including portland, natural, masonry, and pozzolana cements.
In the late 1990s, the leading product types for this industry were building or common brick and face brick, accounting for 91.6 percent of the value of total shipments, which reached $1.82 billion in 2000, compared to $1.77 billion in 1999. Glazed brick and paving, floor, and sewer brick, made up about 5.3 percent of total shipments.
Nearly 99 percent of this industry's product share is composed of glazed and unglazed floor tile and wall tile, including quarry tile and ceramic mosaic tile. Because this industry is so focused on decorative tiles, it is completely dependent on the economic health of the construction and remodeling industries, both of which thrived in the late 1990s due to a booming economy; these industries remained strong in the early 2000s, despite weakening economic conditions, thanks to historically low interest rates.
Refractories are mineral- and chemical-based materials with very high heat-resisting properties, which make them ideal for use in the construction of walls, ceilings, and associated elements of iron and steel industry blast furnaces, glass manufacturing tanks, cement kilns, hot stoves, ceramic kilns, open hearth furnaces, nonferrous metallurgical furnaces, and steam boilers. Most clay refractory products are manufactured in the form of bricks, but refractory clay may also be formed into special shapes, such as the T-sections of refractory pipes or the small stands that support ceramic products during firing in a kiln.
This industry classification includes establishments engaged in the manufacture of clay sewer pipe and structural clay products, not elsewhere classified. Other products include adobe brick, clay chimney pipe, clay drain tile, and clay roofing.
This industry classification consists of establishments primarily engaged in manufacturing vitreous china plumbing fixtures and china and earthenware fittings and bathroom accessories. Items manufactured in this industry include flush tanks, lavatories, bidets, urinals, toilet fixtures, closet bowls, drinking fountains, and sinks.
This category consists of manufacturers of porcelain electronic insulators, molded porcelain parts for electrical devices, other electrical insulators, ceramic electronic and electrical supplies, and spark plug and steatitic porcelain.
This industry consists of manufacturers of art and ornamental pottery, industrial and laboratory pottery, unglazed earthenware florists' articles, and earthenware table and kitchen articles, as well as those establishments primarily engaged in firing and decorating white china and earthenware for the trade.
In 2000, the concrete block and brick industry had approximately 22,365 employees, of which 14,023 were in production. Total payroll expenditures that year were $768 million, and the cost of materials was $1.9 billion.
The products included in this industry are made of concrete, formed and hardened at the cement facility, and shipped in finished form to customers or users. Many of the items were prefabricated parts to be assembled into buildings, bridges, or parking structures.
This category covers establishments primarily engaged in manufacturing portland cement concrete manufactured and delivered to a purchaser in a plastic and unhardened state. This industry includes production and sale of central-mixed concrete, shrink-mixed concrete, and truck-mixed concrete.
The lime industry is comprised of establishments primarily engaged in manufacturing quick-lime, hydrated lime, and miscellaneous lime-related products. It is considered part of the larger concrete, gypsum, and plaster products industry.
Companies predominately employed in manufacturing plaster, plasterboard, and other gypsum products constitute the gypsum products industry. The manufacturers in this industry make products such as acoustical plaster, wallboard, cement, insulating plaster, orthopedic plaster (for casts), plaster of paris, and gypsum rock, lath, and tile.
This category covers establishments primarily engaged in cutting, shaping, and finishing granite, marble, limestone, slate, and other stone for building and miscellaneous uses. Establishments primarily engaged in buying or selling partly finished monuments and tombstones, but performing no work on the stones other than lettering, finishing, or shaping to custom order, are classified in either the wholesale or retail trade divisions.
This classification covers companies that primarily make abrasive grinding wheels of natural or synthetic materials, abrasive-coated products, and other abrasive products. Companies cutting grindstones, pulpstones, and whetstones at the quarry are classified under mining industries.
Serious health concerns have all but dismantled the asbestos industry in the United States. Use of asbestos plummeted after medical studies in the early 1970s linked airborne asbestos fibers to a couple of serious illnesses: asbestosis and mesothelioma.
This category includes establishments operating without a mine or quarry and primarily engaged in crushing, grinding, pulverizing, or otherwise preparing clay, ceramic, and refractory minerals; barite; and miscellaneous nonmetallic minerals, excluding fuels. These minerals are the crude products mined by establishments of Industry Groups 145 (clay, ceramic, and refractory minerals) and 149 (miscellaneous nonmetallic minerals, except fuels), and by those mining barite in SIC 1479: Chemical and Fertilizer Mineral Mining, Not Elsewhere Classified.
A refractory is a product such as brick that is resistant to intense heat. Some of the main uses of refractories are to create fire-resistant construction materials for industrial buildings and to create crucibles.
This category is comprised of firms that manufacture goods made from plaster of Paris, papier-mâché, sand lime, and other miscellaneous nonmetallic mineral products. Examples of industry output include synthetic stones, clay and plaster plaques, architectural plaster work, plaster of Paris sculptures, miniature gypsum images, plaster of Paris flower boxes, and gypsum urns.
