Diffusive model of Pb sup 2+ release by lead-ceramic glazes

A diffusive model for Pb sup 2+ release, both from granulates and from glazes deposed on majolica, was obtained by EPR measurements of CuO-doped Pb ceramic glazes of variable composition due to the substitution of K sup + with Li sup +, Na sup +, Rb sup +, Tl sup +, or Cs sup +, and through the defi...

Summary:A diffusive model for Pb sup 2+ release, both from granulates and from glazes deposed on majolica, was obtained by EPR measurements of CuO-doped Pb ceramic glazes of variable composition due to the substitution of K sup + with Li sup +, Na sup +, Rb sup +, Tl sup +, or Cs sup +, and through the definition of empirical parameters related to composition and to ionic radii. In the case of majolica-deposed glazes, the different emission values were attributed to ionic migration across the glass-bisque interface.
