Clay Gallery

This gallery contains pictures and information for the clays commonly used by club members.  Clays not stocked at the club for member purchase are denoted by an (*) and may be purchased directly from a local retailer (eg, Marjons). 

Note: The club normally Bisque-fires to cone "04" and High-fires to cone "5".  Care must be taken when using cone 10 clays for functional-ware and should be avoided altogether for pieces intended for micro-wave and oven use.
