Dissolution Of Lead Crystal Glass (24% Pbo) In Aqueous Solutions Of Ethyl And Methyl Alcohols

Dissolution of a commercially available lead crystal glass in different concentrations of ethyl or methyl alcohols was studied at temperatures between 25-75 deg C for durations of 0.5-6h. 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.
