Function of Arsenic in Soda-Lime-Silica Glass. Part III. Effects of Temperature....

JSGT 1927 V11 T205-T214

The observations recorded in papers dealing with earlier sections of this investigation were made for melting temperatures ranging from 1300° up to 1400°, and for the founding period of about 22 hours. Moreover, we have shown that similar glasses, melted in tank furnaces of various sizes at temperatures from 1350° up to at least 1400°, and maintained in the furnace for periods up to 5-7 days, also contain arsenic varying in amount from 55 to nearly 100% of that added. In these cases also, the residual arsenic is present largely in the form of arsenate.
