An investigation to determine the effect of fluorine and alumina on the production efficiency of hand-blown lighting ware

JSGT 1958 V42 T261-T270

The results are reported of an investigation into the effects of fluorine and alumina on the production efficiency of opal glass. As a result of the investigation, radical alterations were made to the founding procedure of the glass. Corrections to the batch were applied to allow for the considerable loss of fluorine from the glass by volatilization during founding and for the pick-up from the aluminous china clay tank blocks. Stable production efficiencies were obtained as control of alumina and fluorine was established.
