Making glass has several steps, which can’t be rearranged. First, we have to prepare the materials used to make glass, such as sand, soda, and limestone, and the tools like furnace, roller, and removable mould. Then, the materials are mixed (by reducing them into powder). After that, they’re heated in the furnace, preferable in the constant temperature for about 5 to 6 hours. The result of this heating is divided into two places according the shape desired. In the first place, the melted mixture is flattened by rollers and cooled into a solid plate glass. In the second one, the melted mixture is distributed into the mould, given air pressure, and then cooled. After the solid bottle glass obtained, the mould can be removed. Finally, the glass products are ready to sell or use.
