Note on a Method of Testing the Probable Durability of Tank Blocks

JSGT 1929 V13 T130-T140

Whilst the progress made since the War in the manufacture of tank blocks has been of exceptional character, it is true also to say that the same applies to the rate of melting glass. The output of glass tank furnaces has increased so rapidly that it is no exaggeration to say that the maximum rate is now largely governed by tank block considerations alone.
