Porcelain is a dense and delicate material. It’s famous for its translucency and bright white colour.
Kaolinite, feldspar and quartz are the basic ingredients for most of hard-paste porcelains.
Here is an overview of our technical offer, don’t hesitate to contact us for more details!
Biscuit firing (Temperature: 850 – 950°C):
|
Compositions |
|
Pressed Batts
(Extruded possible)
|
|
• Very precise and stable geometric dimensions
• High resistance to bending at high temperature
|
Pressed Biscuit Setters
|
|
• Enable an easy handling of your tableware pieces even before firing
• Very precise and stable geometric dimensions
|
Glost firing (Temperature : 1 300 - 1 400°C):
The glost firing, is realized at high temperature (1 300 - 1 400 °C). There is a trend to reduce the cycle time from 17-18 h (traditional tunnel or shuttle kilns) to as low as 3 h., thanks to fast firing technology. Silicon Carbide products have become more than ever a must to face these very tough operating conditions.
