Which code does this activity belong in?
Glass and glass product manufacturing establishments are distinguished by their use of silica sand, cullet, or purchased glass as raw materials, which they melt and shape into finished glass products. This distinguishes them from clay product and refractory manufacturing, which works with clay and ceramic materials through shaping, molding, and firing processes. Glass manufacturers differ from concrete product makers, which form products from cement mixtures, and from lime and gypsum producers, which process calcitic limestone, dolomitic limestone, or gypsum materials.
