The Use of Special Alloys in the Glass Industry

JSGT_1937_V21_T247_T262

A survey, based largely on the results of a questionnaire sent to both suppliers and users of special alloys for blowpipes, moulds or parts thereof, machine parts, furnace metal work including lehrs, surface coatings, and miscellaneous uses. Some diversity of opinion was met with concerning the usefulness of a material for a given purpose, which may be due to unrecognised variables affecting the conditions. A noteworthy fact is the improvement recently in the quality of cast iron supplied, due in some cases to the introduction of small amounts of alloying material.
