The Function of Arsenic in Soda-Lime-Silica Glass. Part II

JSGT 1927 V11 T190-T205 

In Part I of this investigation it was shown that when added to a batch consisting of sand, limestone, and soda ash, arsenious oxide is retained in the resulting glass to an extent which varies with the amount added. When the amount in the batch is in the neighbourhood of 2 to 5 parts per 1000 parts of sand practically all of the arsenic remains as a constituent of the glass, partly as arsenite and partly as arsenate. The actual ratio of the arsenite to the arsenate was found to vary somewhat with the concentration, but in many cases two-thirds of the total arsenic present remained as arsenate, although no oxidising material had been added to the batch.
