I N T R O D U C T I O N

In a recent re-publication of the results of water solubility determinations using the weight-loss method, Hamilton and Oxtoby (1986) have devoted considerable space to criticism of the method of determination of water solubilities employed by Dingwell et al. (1984). In this comment we wish to respond to the criticisms of Hamilton and Oxtoby (1986).

V A C U U M F U S I O N M A N O M E T R Y

In the study by Ding well et al. (1984), the solubility of water in several haplogranitic melts was determined using the vacuum fu-sion manometric system developed by Harris (1981). The method involves four essential steps: (1) a water-saturated melt is synthe-sized, (2) a bubble-free sample of quenched glass is obtained, (3) a weighed sample of the glass is fused in a vacuum and the evolved gas is collected in a liquid nitrogen cold trap, and (4) the collected gas is liberated from the cold trap and the pressure exerted by the gas in a known measuring volume is recorded. The amount of gas liberated is readily com-puted and compared with the mass of the glass sample to obtain a solubility value.

C O M M E N T S OF H A M I L T O N A N D O X T O B Y

Hamilton and Oxtoby (1986) make two criticisms of the method of Dingwell et al. (1984).

First, they point out that our weighing er­ror of ± 0.003 mg yields a value of ± 15%

1 Manuscript received November 20, 1986.

[JOURNAL OF GEOLOGY, 1987, vol. 95, p. 583-584] © 1987 by The University of Chicago. Al l rights reserved. 0022-1378/87/9504-0010$! .00

for our smallest sample size of 0.020 mg [misreported by Hamilton and Oxtoby (1986) as 0.6 mg]. The ränge of glass sample masses used by Dingwell et al. (1984) was indeed from 0.020 to 0.600 mg b u t , with the excep-tion of NOR composition, all glass wafers were greater than 0.100 mg thus yielding weighing errors of less than ± 3%. In addi-tion, NOR was analyzed in duplicate with a second wafer weighing 0.072 mg (weighing error = 4.2%). In fact, more than half of the samples were > 0.200 mg. Finally, on this point, general criticism of the data of Ding­well et al. (1984), based on sample size, is irrelevant because the method itself is not, in general, restricted to small samples.

Second, Hamilton and Oxtoby (1986) ex-press concern over the methods of sample handling employed by Dingwell et al. (1984) prior to their fusions. We were indeed con-cerned about possible water loss or gain dur-ing the sample-handling and tested the possi-bility of handling errors in the following manner. The most peralkaline glass, EAK, was relatively vesicle-poor due to its lower viscosity and chips of vesicle-free glass suit-able for analysis were readily obtainable di­rectly from the experimental Charge. As a check against water loss or gain during our routine sample-handling technique, an un-ground chip of vesicle-free EAK glass was loaded into the vacuum fusion system, ana­lyzed and compared with the results of runs with glass wafers. The comparison yielded an excellent agreement, illustrating that the preparation method was not destructive with respect to water content. Also, on this sec­ond point, the very good precision observeci by Dingwell et al. (1984) for sample wafers of varying mass, aspect ratio, initial vesicularity and final thickness (all factors which might

584 DISCUSSION AND REPLY

scatter replicate determinations if the physi-cal handling of samples were a problem) fur­ther demonstrates the insensitivity of the wa­ter content to the sample handling.

A D V A N T A G E S OF V A C U U M F U S I O N M A N O M E T R Y

The vacuum fusion manometric method of determining volatile solubilities has advan-tages over the weight-loss technique.

First, as demonstrated by Dingwell et al. (1984), the method is applicable to a wide ränge of sample sizes. The main advantage is the extension of the lower limit of the ränge of sample sizes. The weight-loss technique is limited to larger samples (Hamilton and Oxtoby 1986). The study of Dingwell et al. (1984) was designed to demonstrate the U t i l i t y

of the vacuum fusion manometric method for dealing with water solubility at the low pres-sures (less than 2 kbars) and low tempera-tures (800°C) relevant to the petrogenesis of many silicic rocks. This P-T-X region of wa­ter solubility determinations had been previ-ously neglected. Thus the vacuum fusion manometric method is effective for, but not restricted to, a ränge of smaller sample sizes.

Secondly, the liberation of gases from the cold trap of the vacuum fusion system results in a stepwise collection and measurement of the gas content of samples which have more than one dissolved volatile species. The work of Harris (1981) has illustrated that this
