the first flow diagram illustrates the process of glass container production, and the second diagram shows steps in the process of recycling used glas
overall, glass is made using three main raw materials, and that the manufacturing process consists of four distinct stages. It requires five steps to turn used glass into new glass products
at the first stage in the production of glass, sand, soda ash, limestone and other chemicals are mixed together. Next, this mixture is taken to melt in a glass fumace at approximately 1500 degrees.
