Palladium - Palladium (pay-law-dee-um) is a dense and lustrous, precious white-silver metal. Discovered in 1803 by William Wollaston, it is named palladium after the renowned asteroid Pallas, which is named after Athena, the ancient Greek Goddess of Wisdom. A cousin of the platinum metal group, this rare metal is popular for fine metal jewelry, findings and beads.
Patina - The coloration that occurs in certain metals when they are exposed at length to the atmosphere. A thin, greenish layer appears on the surface of copper and bronze; a reddish effect on gold. An artificial patina can be created with acids or electrolyte.
Pearl Essence - Also called essence d'orient. A crystalline substance extracted from fish scales and combined with acrylic resins. Used to make imitation pearls. In better imitations, the essence is applied over opaline glass beads; in cheaper imitations, over plastic beads. Discovered in 1565 by Jaquin, a French manufacturer of rosaries, when he accidentally dipped some pearls into water in which he had washed fish. Refined versions today produce spectacular results.

Older or classic pewter contains tin while lower grades of pewter may contain lead or zinc and have a darker silver-grey color. Newer or modern pewter uses antimony or bismuth rather than lead.

Polishing - The process in the last stage of metal finishing in which a rotating instrument is dipped in a polishing substance. Increases shine and eliminates flaws.
Polymer Clay - A plastic sculpting material made of polyvinyl chloride (PVC), used to create jewelry beads and components. Kato Polyclay® is a brand of polymer clay.
