Abstract

A ceramic crucible with enhanced heat proofing has the crucible supported in an outer crucible of a different clay to that of the inner crucible. The outer crucible is made from an industrial quality clay and is bonded to the inner crucible. During heating the temperature rise is more even in the inner crucible, resulting in less cracking.

BeschreibungDescription

"Keramische Feuerschale ""Ceramic fire bowl"

Keramische Feuerschalen bestehen nach meiner Information aus einer einzigen keramischen Masse ( evt. mit Armierung).According to my information, ceramic fire bowls consist of a single ceramic mass (possibly with reinforcement).

Zum Einen erhitzen sich die Schalen auch außen, zum Anderen ist bei starker Befeuerung mit Rissbildung zu rechnen.On the one hand, the shells also heat up on the outside, and on the other hand, cracks are to be expected when heated to high temperatures.

Die im Schutzanspruch angegebenen Erfindung führt zu einer viel langsameren und ausgeglicheneren Erwärmung der Feuerschale an der Oberfläche der Außenschale: dadurch wird die Schale außen weniger warm und Rissbildungen verhindert.The invention specified in the claim leads to a much slower and more even heating of the fire bowl on the surface of the outer shell: this makes the outside of the bowl less warm and prevents cracks from forming.

Die Feuerschale ist gekennzeichnet dadurch, daß in eine ca 1,5 cm starke " Außenschale" aus industrieller Schamottetonmasse eine 2-2,5 cm starke "Innenschale" aus Isolier-Schamottemasse ( Schamottemasse mit Zuschlägen!The fire bowl is characterized by the fact that an approximately 1.5 cm thick "outer shell" made of industrial fireclay mass has a 2-2.5 cm thick "inner shell" made of insulating fireclay mass (fireclay mass with additives!

eingebracht wird.is introduced.

Die Innenschale wird mit der äußeren verbunden, indem die noch feuchte Außenschale spiralförmig angeritzt und die Isomasse eingedrückt und angeklopft wird. Die beiden Massen sind dadurch keramisch verbunden und werden in einem Brand zusammen geschrüht.The inner shell is connected to the outer shell by making a spiral-shaped scratch in the still-wet outer shell and pressing in and tapping the insulating mass. The two masses are thus ceramically connected and are fired together in one firing.
