Operating Procedure applies an electric furnace for burning the biscuits or the torching of the glaze. There is a possibility that objects burned fractured. Some causes are:
- If many are broken, the possibility of too rapid preheating.
- If any of them have a lot of cracks, the possibility of passing a temperature of 570 ° C, the temperature increase in the heat too fast.
- If only a few objects that crack, can be caused when the process of formation, there are air bubbles or drying unfavorable.
record
Furnace cooling time is at least equal to the time required for combustion. When the temperature inside is already below 100 ° C, then all the ventilation holes are opened and the furnace door was opened slightly. Moments later the object can be disassembled and removed. Things that need special attention when burning and unload objects are not to forget to wear the tools of health and safety.
