Forgotten but not lost: the secret of Coade Stone
Abstract
Coade Stone was widely used as a decorative building material in the Georgian Period, and its success has been attributed to some secret process or formula. Analysis using optical and scanning electron microscopy with energy dispersive x-ray analysis has shown it to be a stoneware ceramic made from well-known and readily available raw materials. A formula for artificial stone which was published in 1850 gives a similar composition, so that the mystery which is associated with the material is unlikely to be justified.
