Ptolemaic and Roman faience tends to be typologically and technologically distinct from the earlier material: it is characterized by the widespread use of moulding and high relief on vessels. A very unusual and finely made group of figures of deities and falcons in the Metropolitan Museum of Art in New York, apparently representing hieroglyphs that are elements from a royal inscription, perhaps from a wooden shrine, is decorated in a form of champlevé (typically a technique for enamel on metal). Depressions in the faience body were filled with coloured "vitreous pastes" and refired, followed by polishing.
