We have investigated the effect of A1/B ratio on the Product Consistency Test (PCT) response. In an aluminoborosilicate soda-lime glass based on a modified International Simple Glass, ISG-3, the A1/B ratio varied from 0 to 0.55 (in mole fractions). In agreement with various models of the PCT response as a function of glass composition, we observed a monotonic increase of B and Na releases with decreasing A1/B mole ratio, but only when the ratio was higher than 0.05. Below this value (A1/B < 0.05), we observed a sharp decrease that we attribute to B in tetrahedral coordination.
