Cooling after ceramic firing
(Relexation cooling is recommended for lang span, bulky frameworks)
HeraCeram: Rapid cooling
At the end of the programm the firing platform is completely and firing tray with objects is removed emediately. The firing tray can cool next to the furnace on a fire-resistant tray.
Others: Follow the instructions of the ceramic manufacturer.
