Product Description
Introduction of Cordierite-Mullite Kiln shelf
Cordierite-Mullite kiln shelf is widely used to fire ceramic, porcelain and pottery.It is cheap and reliable.It can work under
1250℃ in furnace. It has good thermal shock resistance, if you put it into a 1000℃ furnace, and then take it out from furnace, it is still OK.It can bear quick temp-up and temp- down.
The practicality of cordierite, as a refractory, can be better appreciated when comparing it to alumina. Although alumina by
itself, is more refractory than cordierite, it is also much more prone to cracking when subjected to thermal shock. By comparison, cordierite has low expansion and much less expensive. No wonder that cordierite kiln shelves are common.
While Cordierite ceramic vessels could be made (e.g. ovenware), the material has such a low thermal expansion it is very difficult (or impossible) to match a glaze (without crazing). Notwithstanding this, many recipes can be found for cordierite ovenware or flameware. However these are seldom fired above cone 10 so any thermal shock resisting behavior they have is attributable to grog content or open fired matrix rather than to any cordierite development (which is of course not happening). We can also customize according to your requirement.If you think Cordierite-Mullite kiln shelf is not good enough, we can also recommend sillicon carbide kiln shelf.
