Glass, as one kind of material that is highly widely used and manufacture, is relatively environmental friendly and saving more energy than metal and plastic in the process of making. Glass container always present green. Glass was consisted of several raw material, such as natural ore, silica sand soda ash, quartz stone, caustic soda, and limestone. Glass container, possessing high degree of transparency and resistance to corrosion, is always used to store the chemical agent. Also the making process is relatively simple. About 45 percent of silica sand, 15 percent of soda ash which helps melt the silica evenly, 10 percent of limestone which make the finished product more durable and recycled glass, is putted into the furnace and heated under the 1500 degree celsius in 24 hours. Then the molten glass pulls out of furnace and was split into precise amount that is required for making each glass container. Then those precise amount were transported into each bottle forming machine and comes out as miniature version of the bottle, and each bottle moves into the blow mold, which blows and stretch the glass outward to form final shape of bottle.
Glass also is known as 100 percent recyclable and can be fully recycled without any loss quality. A great amount of releasing of carbon dioxide us saved by recycling waste glass into new item, and the ingredient of making glass is largely contained by the recycled glass.
