Glass-making

To make glass, you would need some materials and tools. The materials are sand, soda, and limestone. The tools are furnace, removable mould, rollers, and connecting pipes. First of all, sand, soda, and limestone are mixed in certain composition. Then it will be burnt in a furnace with an extremely high degree of temperature. The next step you have to do is to decide what shape the glass is going to be. If you want to make a plate glass, then the glass is channeled by connecting pipes to the roller. Certain pressure is given by the roller to make the shape of the glass plate. If you want to make a bottle glass, then you should channel the glass to a removable mould bottle-shape. And with certain tool, you can press the air to fill in to make some space inside the bottle glass. Furthermore, you can decorate the glass with certain chemical substances.
