Once the mold has been loaded with the proper amount of material, the machine's operator then forces its long handle down with a pressure of 70 to 100 pounds (exerting, in turn, 40,000 pounds of ...
Now the selection of the raw materials is made. While it might seem reasonable to choose one raw material for each of the oxides, it is typically more effective to seek out lower cost materials that contain more than one component. For example, anorthite, CaO Al 2 O 3 2SiO 2 (molecular weight=278 g/mol) is a good choice for supplying the Al 2 O 3.
