11.15 Glass Manufacturing - US EPA
www3.epa.gov11.15 Glass Manufacturing 11.15.1 General1-5 Commercially produced glass can be classified as soda-lime, lead, fused silica, borosilicate, or 96 percent silica. Soda-lime glass, since it constitutes 77 percent of total glass production, is discussed here. Soda-lime glass consists of sand, limestone, soda ash, and cullet (broken glass). The
