Process for preparing decorative phosphate ceramic materials

Abstract From the Canadian patent

Abstract, The present invention relates to a method by which a composition which will provide a foamed phosphate ceramic material is cast upon a support surface comprising regions having a substantially smooth character, being of relatively low surface energy and, having the ability to release from the cured phosphate material. In those regions where the smooth coating contacts the phosphate open cells will result whereas, in other regions closed cells will result. One preferred substrate against which the phosphate material can be cast is a wax material.
