Decreasing Lead Exposure From Lead Crystal By Sol-Gel Coating

Investigations to develop sol-gel coatings on lead crystal glasses were carried out to reduce the migration of lead into beverages. Three compositions were tested as coating materials. The best result was obtained from the B2O3/SiO2 system. The results showed that the coating reduces the leaching of lead to some percent of the value of uncoated surfaces and does not lose its effectiveness after 20 cycles in a heavy duty laboratory dishwasher.
