A simple, low firing glaze used on soft paste ceramics. Lead glazes may be sprinkled or thinly painted on a clay body. Lead glazes are used on clay that can be fired below its volatilization temperature of about 1150C. Lead glazes produce a lustrous, opaque surface, but they are no longer in common use because of the potential for lead poisoning. Examples of lead salts used as glazes are: lead antimonate ([http://cameo.mfa.org/materials/fullrecord.asp?name=Naples yellow Naples yellow]), [http://cameo.mfa.org/materials/fullrecord.asp?name=lead carbonate, basic lead carbonate], [http://cameo.mfa.org/materials/fullrecord.asp?name=lead chromate lead chromate], [http://cameo.mfa.org/materials/fullrecord.asp?name=lead oxide lead oxide], [http://cameo.mfa.org/materials/fullrecord.asp?name=lead silicate lead silicate], and [http://cameo.mfa.org/materials/fullrecord.asp?name=lead sulfate lead sulfate].
