Six crystal glass compositions without added lead were used to prepare standard beakers having a volume of ca.240ml. The experimentally determined concentrations of the elements in the glass beakers were in satisfactory agreement with the theoretically predicted values. The degree of leaching of selected elements from these beakers was determined using 4% acetic acid as described in ISO 7086-1:2000 standard test. In addition, to the degree of leaching by 4% acetic acid, migration into cola, red wine, 40% ethanol & 0.3% citric acid was also determined. Elements tested included antimony, barium, bismuth & zinc as these were considered to be of most interest. Results showed it is possible to produce durable glass containing no added lead. Overall quality of the glasses was good & the concentrations of the various elements leaching was very small & not considered hazardous.
