larger image		THE OPAQUE QUALITY comes from the quartz sands of high purity, when reduced to a molten state, at a temperature of approximately 2000° C. The high temperature produces a vitreous material characterized by the presence of a multitude of gaseous micro-bubbles, which by diffracting the light, gives the material its opacity. The term opaque silica is mainly used for molded or centrifuged parts, while the product obtained by drawing is normally referred to as translucent. Opaque silica glass offers a number of exceptional properties, such as: Extreme Hardness Low Expansion Excellent High Temperature Resistance Extreme Chemical Purity Excellent Corrosion Resistance Excellent Electrical Insulation Properties Remarkable Stability Under Atomic Bombardment
