The approximate order of effectiveness of the more common metals is cobalt, magnesium, cerium, lead, chromium, iron, nickel, uranium, and zinc. These are usually prepared as the linoleates, naphthenates, and resinates of the metals. Paste driers are commonly the metal salts (acetates, borates, or oxalates) dispersed in a dry oil.See Soap.Note: The spelling dryer refers to equipment used for drying (of paper, textiles, food products, etc.).
