Adamantine Porcelain

Adamantine porcelain is a dull white material, very slightly translucent, which appears to shine more brightly than expected.  It is as hard as diamond when struck, but can be treated so that it can bend like soft tin.  It is made by fusing diamond with a rare alchemical metal.  It is about half as heavy as steel.  It may be substituted as a spell component for a spell that requires a diamond, and is about as valuable.   The Eliomandrine empire produced large amounts of this material, creating golem-like fighting constructs called Anahita and the enormous Porcelain Temple in Cothon Carinbalq.  There exist a few pieces of equipment and symbols of power made of the material.
