Notes on Pot-clays and the Manufacture, Use and Treatment of Glass-house Pots

JSGT 1924 V08 T045-T057

The author of this paper relates some of his experiences with glass-house pots and pot-clay mixtures. The notes are presented with the view of bringing glass manufacturers to realise some of the material factors and limitations which govern the proper use of glass-house pots. Further notes are included presenting a few simple works tests for examining pot-clay mixtures and methods for obtaining greater efficiency in the life of pots. The author's experience has been acquired from a practice extending right back to the mining of the clays from the seams and the preparation of pot-clay mixtures. His later experience in association with many glass-works, both old and modern, has aIIowed him the opportunity of comprehending and studying the conditions which prevail in the use and treatment of fireclay goods, and of realising the general difficulties glass manufacturers have to contend with. It must be noted that the comments are made more for the guidance of the practical man in the glass factory, and in no way are they put forward as a complete thesis on the subject.
