is the label name for cool top platforms, which were developed from the bulkhead glass works (today bulkhead AG) in Mainz. Cerium on plates have a high heat permeability and practically no thermal expansion. They possess a smooth, nonporous surface.

The glass ceramic is a part-crystalline material, which results from an incomplete crystallization ("“Keramisierung"”) of suitable glasses. During the production ranges with an arranged crystal structure develop in the glass matrix. This has a negative pulls together thus when heating up. If the relationship from glass to crystal phase is suitably stopped, then develops a material, which does not expand when heating up as well as. Main parts of the glass ceramic for cerium parboiling surfaces are lithium, aluminum and silicon oxide (so-called "“reading glass ceramic"”).

The glass ceramic gets over abrupt temperature shocks to 750"° Celsius intact.

Applications

The furthest spreading found the cerium parboiling surface in connection with the electrical radiation heating. Here underneath the glass ceramic of arranged heating conductor by electrical resistance heating up to the red glow one heats. The radiant heat sent by the leader passes through the glass ceramic, so that it can heat the soil of the pot or the pan. Further heating systems, which are used in connection with cerium parboiling surfaces, are open Gasflammen and electrical induction pick-up coils.

There originally the glass ceramic (trade name Zerodur) for mirror carriers was developed by astronomical telescopes and is for decades in the employment.

Substantial physical characteristics

• thermal expansion: quasi zero
• high temperature/time maximum stress
• Spalling resistance
• small heat conductivity
• high mechanical firmness
• system-optimized infrared (IR) - radiation permeability

(Notes: Ceran does not contain cerium, even if it lets assume the name, this infrared radiation would block)

These characteristics lead to the fact that a pot on a cool top platform very fast and with only small losses is heated up. The cook field becomes hot thereby only directly under the pot.

The black shining glass ceramic of the cerium parboiling surfaces is strong for visible light absorbing. In examination its color is reddish-brown (today) or red violet (earlier types).

Beside the well-known black glass ceramic there are also transparent glass ceramics, like e.g. (label name of bulkhead), which finds among other things as heatproof sight in furnaces and fire-places use. It continues to give Nippon Electric Glass or ARCTICFIRE also white glass ceramic variants like NEOCERAM the company. These materials are either vaguely translucently (transluzent) or completely intransparent (opak).
