Temporal evolution of the estimated thickness of the alteration layers and amount of glass altered. The average estimated thickness of the alteration layers a and estimated amount of glass altered b from the total concentrations of B leached into solution. Points are plotted as the average of triplicate leachate measurements with errors calculated as one s.d. of each set of triplicate aliquot measurements taken from each vessel at each time. The blue solid line with diamond markers and the orange dotted line with square markers in both figures represent the two datasets of the duplicated experiments. The open diamond markers represent the same experiment as the filled blue diamond markers in which the leachant was refreshed in one vessel after the sampling of the 28 day aliquots followed by a further 70 days of leaching in fresh DI water (98 days total dissolution).
