Technical glass

Colored quartz tubes

Red quartz tube

With the addition of trace elements may be obtained quartz of a different color. 

Available colors: red, dark red, pink, blue, black.

Red quartz (as well as pink and dark red) transmits infrared and blocking ultraviolet and partly visible radiation.

Application: heaters to the infrared, sterilization devices, microwaves, cookers and electric furnaces, dryers to the infrared.

Properties and chemical composition of colored quartz as well as other types of quartz glass, are discussed in detail in chapter Our offer/Technical glass/Types of materials/Quartz glass.  Below presents the most important of them.

Properties of different types of glasses are discussed here.
