Corrosion of a commercially available lead crystal glass by different aqueous solutions of ethyl and methyl alcohols were studied at 75 deg C for 1/2-6h. Increasing the concentration of alcohol increased the release of Pb and decreased the release of Na, K and Si as well as the weight loss. The quantities of Pb released by both alcohols were significantly lower than that of Na, K or Si. 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 the compounds formed.
