Coade stone process and formula
The production process for Coade stone comprised a number of stages. First of all a model of the proposed piece was made, from which a plaster cast/mould was taken. The Coade clay was then inserted into the mould and fired, before being baked in a kiln at 1,100 degrees Fahrenheit for 4 days The, then secret, formula for Coade clay comprised a mixture of 10% grog (a finely crushed waste from the kiln); 5-10% crushed flint; 5-10% fine quartz or sand; 10% crushed glass; and 60% ball clay (from Dorset or Devon).
