APPLICATION
Suitable in various hardnesses for working by hand and on the lathe and for cast presses and with iron moulds. The lower thermal expansion makes this clay more resistant to impacts, and is suitable for making objects for the kitchen oven, or in any case subject to a moderate temperature change.
PHYSICAL PROPERTIES
Shrinkage during cooking (%): 5 – 7
Water absorption (%): 14 – 16
Alpha 10E-7K expansion coefficient: 73 – 75

Dark cooked red
COOKING
We recommend baking the biscuit at a temperature between 970°C and 990°C.
The second firing can be carried out at temperatures suitable for the glaze to be applied to this specific mixture, respecting in any case the expansion coefficient in order to avoid problems such as cracking or flaking.
This clay can be fired indifferently in continuous or intermittent, gas or electric kilns.
