Few Steps to Make Glass

Glass is a transparent, everyday object that can be made through series of process. To make it, we need sand, soda, and limestone, all three on equal ratio. First, the three ingredients are mixed and inserted into a furnace, then baked until they form some sort of substance. These substances are then split in two to make two kinds of glass: plate glass and bottle glass. Half of these substances are then flattened with rollers and made to harden to make plate glass. The other half are inserted into a removable mound with hollow middle that shaped like bottle. The air is inserted to make hollow place in the middle of the glass-substance. And finally, when the glass hardened, that removable mound is then removed and we have one glass bottle.
