摘要:

SummaryThis new factory, constructed in 1918‐19, is worthy of note by reason of its expensive (7 to 8 hundred thousand dollars per unit) and permanent construction, by reason of the high quality of glass produced in continuous tanks, and by reason of its efficient design and arrangement and the extensive employment of mechanical devices throughout. This paper gives a detailed description of the factory under the following headings: Historical; Buildings, Warehouse, and Factory; The Hardford ‐ Fairmont Feeder with description operation; The Batch System and the Batch; The Stacks; The Laboratory; and Selecting and Packing the W

摘要:

summaryComparing the effects of equal molecular additions of the various components of the glazes in this study, it was found that ZnO and feldspar overcome crazing, ZnO being the more effective. MgO, BaO and CaO tend to produce crazing, MgO having the greatest tendency and the effect of BaO being somewhat greater than that of CaO. SnO2has no effect on the crazing.Increase of clay is more effective in overcoming crazing than any other changes that can be made in the glaze formula. Addition of small amounts of clay are more effective in overcoming crazing than much larger additions or substitutions of the other components.Increase of flint (per molecular equivalent) is less effective in overcoming crazing than increase of either clay, ZnO or feldspar, although, generally, considerable more flint than clay or ZnO can be added without appreciably changing the maturing point of the glaze. In many cases, increase of flint will not overcome crazing in a glaze.
