Additional Note on the Analysis of Glasses containing Phosphate
JSGT_1929_V13_T270_T279
Shortly after the publication by us of the previous paper* on this subject it was observed by one of us that the originally quoted method t for the removal of P2O5 by means of silver carbonate and silver nitrate was not satisfactory in the case of a complex glass containing P2O5 in amount, say, of 5% or more. Accordingly, the method previously given has been more fully investigated in the laboratories at Sheffield and Canning Town in order to test the conditions under which it breaks down and to work out a procedure of more general application.
