The intrinsic dissolution rates of nine borosilicate waste glasses were extracted from the results of MCC-1 tests conducted for durations long enough that the solution pH reached a nearly constant value but short enough that the buildup of dissolved species did not affect the dissolution rate. The effects of the pH and temperature on the measured rates were deconvoluted to determine the sensitivity of the rate to the glass composition. The intrinsic dissolution rates were similar for all of these glasses and were not correlated with the glass composition. The mean and standard deviation of the intrinsic dissolution rates of these glasses are log k{sub 0}/[g/(m{sup 2}{center_dot}d)] = 8.2 {+-} 0.2.
