The diagram describes how glass is manufactured and recycled.
There are four main stages in the glass generation process, from mixing to glass products. Meanwhile, the process of recycling involves five steps, beginning with gathering used glass and ending with new products.
At the first stage in the process, materials including sand and soda ash are mixed, limestone and other chemicals are also added. Following this, a glass furnace is employed to melt this mixture at approximately 1500oC. Then, molten glass experienced shaping step through blowing to create final products such as glass containers.
