“…The densities of 37 soda-silica glasses, containing from 13 to 50 percent of soda, were reported in a previous publication [1]/ and certain relations between specific volume and composition were suggested . Since those data were published, many new glasses in the same range of composition have been made.…”

“…In this ra nge tho densities of our glasses were lower . After table 1 was prepared, the 14 soda·silica glasses used in treatment 4 (see table 1) were re·treated by the same procedure, except that 3 cooling rate o( about 2° per hour was used. The resulting densities were as follows: (4) As was expected, these densities are greater than those resulting from treatment 1. The new densities, al· though remaining lower than those of Morey and Merwin (or glasses containing less than about 23 percent of soda, were somewhat hillher than theirs (in tho order o( about 0.003) for glasses containing moro than about 27 percent o( soda.…”

Certain relations between the specific volume and composition of glasses of the soda-silica series have previously been rep orted. Additional glasses were made in the same series and also in the potash-silica and soda-potash-silica series. The glasses were analyzed a nd their densities measured. Analysis of the new data suggests tha t the sp ecific volume-composition relations change definitely at compositions approximating those of eutectics, instead of at those of simple molecular ratios, as previously reported.

“…3), it is probable that the results have some qualitative significance. This is further substantiated by the observation that the breaks indicated are essentially those shown by the more precise data for the den sities of these same glasses published by F. W. Glaze and his colleagues [10,11], and for index of refraction on the Na20-Si02 glasses [12] . The Li20-Si02 glasses sorbed much less water than did the N a20 -Si0 2 and K20-Si02 series, and, in fact are knowl1 to bc far superior to the latter in their ability to maintain a clear surface.…”

Hygroscopicity of optical glasses as an indicator of serviceability

Several modifications of a powder-hygroscopicity method have been tried as a rapid means of determining the serviceability of optical glasses, i. e., their ability to maintain a clear polished surface under normal conditions of service. The method has been applied to a wide variety of glasses, and it shows the typical optical glasses in common use to be much less hygroscopic than the average commercial sheet and container glasses. In fact, many of the optical glasses even compare favorably with the better chemical laboratory wares, such as Pyrex, Tamworth, and Kimble N-51-a. This grouping of these glasses of s uch very dissimilar chemical durabilities serves well to emphasize that the;capacity of aglass to maintain a clear surface upon exposure to the atmosphere, and its chemical durability as conventionally determined are two inherently different properties. A comparison of the hygroscopicity valu es of the Corning 015 electrode glass with those of the optical and chemical ware glasses whose electrode capacity is very poor suggests strongly that the pH resp onse of a glass is primarily a function of its hygroscopicity. Tests made on a limited number of glasses of the binary series Na20-Si02, K 20-Si02, Li20-Si02, and PbO-B20 a appear to reflect some of the critical compositions of the respective phase equilibrium diagrams.

“…The density of samples from each of the five glasses was d etermined by the well known buoyancy method [36] using distilled water as the immersion liquid. The values for the five neodymium-doped glasses are given in table 10, where the limit of reproducibility is esti-, mated to be 3 in the fourth decimal place.…”
