Task3: process

There are a similar way and process in making a plate glass and bottle glass. The process are contains four main steps. First, prepare sand, soda, and limestone and put them into the furnace. Make sure that the three items are mixed well. Second, burn the mixed sand, soda, and limestone in a high temperature until they dissolve and form a liquid species. Third, divide liquid species that just burned within two edges holes. First edge hole functioned to make a plate glass and the second edge to make a bottle glass. Fourth, from the first edge hole, the liquid that begin to hard are flown into the rollers to shape a flat glass and adjust the thickness. From the second edge hole, the liquid are flowed with air and then flown into a removable mould, and after a moment we can remove the hard glass from the mould.
