Dissolution of a commercially available lead crystal glass
(24% PbO) in different concentrations of ethyl or methyl alcohols was studied at temperatures
between 25-75 degrees C for durations of 0.5-6 it. increasing the concentration of alcohols
increased the release of lead and decreased the release of Na, K and Si as well as the weight
loss The amount of Pb released by both alcohols were significantly lower than that of Na, K or
Si. Weight loss was slightly higher in the case of ethyl alcohol. The results obtained were
explained by considering the mechanisms of attack by which different cations are released from
lead alkali silicate glasses by aqueous solutions and the solubility of reaction products in the
attacking solutions.
