A new glaze composition was characterized and compared with one studied previously in order to evaluate structural model relating lead‐ion stability and coloring‐ion content to the vitreous system in which they are found. This model is based on the geometrical arrangement of the ionic network, depending in turn on the preferred coordination of the cations involved. The stability of the ionic structure, as indicated by release of Pb 2+ on acid attack, is correlated with the coordination of sites occupied by network modifiers, i.e. cations producing cubic coordination were associated with increased Pb 2+ release, whereas the opposite ccurred with those producing anti prismatic coordination.
