Bottle-glass and Glass-bottle Manufacture
T037-T049 (13 pages)
Although there are various phases of the subject of bottle glass and bottle manufacture which all need discussion, the author considered that in the present paper he might usefully make his contribution under the two headings of quality and quantity, or durability and production. The author has found, in connection with the various types of automatic feed devices now coming into use, a great tendency to use very soft batches. The nature of the device, indeed, calls for a soft batch; but the engineer appears in many cases to have been working without collaboration with the chemist, and to have come perilously near, in some instances, to making a non-durable glass.
