<p>5.  Steatite substrates are placed into precision machines which automatically silk screen the precious metal conductive materials for the slider and end terminations.  Substrates are then fired to temperatures in the range of 1,500 to 2,000 °F in tunnel kilns. The cermet resistance materials, composed of glass and precious metals suspended in a liquid carrier, are then screened onto the substrate, dried, and returned to the kilns for final firing.  The inherent characteristics of cermet afford resistance ranges from 10 ohms to 2 megohms, whereas carbon elements are limited to the high ranges, wirewound to the low and metal film to the middle ranges.
