The muffle (10) has a retaining chamber limited by a bottom side (11), top side (12) and lateral and/or rear-side wall elements (13-15), where one of the wall elements is permeable for infrared (IR) radiations. A reflection element reflecting the radiations is arranged in the area of an external surface of the wall element, where the surface is turned away from the chamber. The wall element is made of glass or glass ceramic, and the reflection element is applied as a tin oxide coating, azo coating and indium tin oxide coating, and absorption elements are formed of imprinted ceramic colors. |
