WebThe Czochralski process of gem synthesis involves the melting of various elements in a platinum crucible. A small gem crystal (called a seed) attached to a rod is then dipped into the melt and slowly pulled away as the crystal grows around the seed. For this reason, the Czochralski method is also known as crystal pulling. WebSuch glasses are made from three main materials— sand (silicon dioxide, or SiO 2 ), limestone (calcium carbonate, or CaCO 3 ), and sodium carbonate (Na 2 CO 3 ). Fused silica itself is an excellent glass, but, as the melting point of sand (crystalline silica) is above 1,700 °C (3,092 °F) and as it is very expensive to attain such high ...
