Flow Tests in Small Glass Tanks

JSGT 1931 V15 T119-T128

Several times during the past four years tests on the flow of glass have been made on small reheating tanks used in the manufacture of glass tubing and bulbs. The indicator employed for tracing the currents of glass in colourless glass was either of cobalt-blue glass or cobalt oxide. Although the temperature distribution was not measured, this colour indicator proved very useful and for this reason the records are now published.
