Experimental factors in glass leaching at high temperatures

Three factors which may influence the outcome of high temperature tests of glass leaching rates, temperature cycling, solution replacement, and glass drying between runs, have been examined. Solution replacement and glass drying have also been investigated in room temperature tests. An easily leached glass was used throughout. Temperature cycling has a small effect which may be compensated in calculating leach rates. The effect of solution replacement depends on the rate and extent of attack. Glass drying has no effect either at high temperature or at room temperature. (author)
