Process for preparing decorative foamed phosphate ceramic materials

摘要

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.
