The Detection of Selenium in Decolourised Bottle Glasses

JSGT 1927 V11 T386-T393

In connection with control work in a bottle factory at which flint glass containers are made, it is occasionally desirable to examine bought flint cullet, and in view of the fact that either or both selenium-decolourised or manganese-decolourised cullet may be offered for purchase, it is of some interest to be able to distinguish the one kind from the other. With the object of devising a routine test for bought flint cullet, a method for detecting selenium in decolourised glasses was sought, and as no simple method appeared to have been described in technical literature, an investigation was undertaken to work out the details of a suitable test.
