Copper

This well-known pure metal, with its distinctive pinkish sheen, is the best widely available purifier and amalgamator among metals. It is soft and easily worked, widely known. The wizard and especially the priest seeking to work with a substance or item not suited to his or her faith or purpose can make the offending item usable by adding at least half the item’s weight of copper to the item. (For example, by sheathing it in copper or adding a longer handle plated in copper, or similar means.) Holy or unholy water should not be stored for any length of time in copper vessels, because the metal will neutralize either in a few months, changing them to normal water.
