title: [Lead elimination by traditional curing].
abstract: OBJECTIVE
  To evaluate traditional acidic curing as a preventive method for reducing lead content of glazed ceramic ware.
  
  
  METHODS
  In 27 ceramic ware pieces from four states in Mexico, the level of residual lead was determined through atomic absorption spectrophotometry after four washings with acetic acid 3%.
  
  
  RESULTS
  The lead content of the vinegar washing diminished proportionally with the number of washings, although it remained highly above the permissible levels of this metal (2.5-7.0 p.p.m.).
  
  
  CONCLUSIONS
  Traditional acidic curing of glazed ceramic ware is not a useful preventive measure for reducing lead exposure.
