Wholesale Cordierite-Mullite kiln shelf with low price for kiln furniture
1. 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.
