摘要:

ABSTRACTThis paper is a progress report covering the work done by the Bureau of Standards during the past three years on the problem of cast glass pots. The work done is essentially an application of the results of research reported in previous Bureau publications and contains data on body compositions, the arching of pots and their resistance to optical glass. The following conclusions were made: (a) The casting of porcelain glass pots has passed the experimental stage; (b) The content of plastic clay is not of prime importance as long as the body will cast satisfactorily; (c) Proper watersmoking practically eliminates fissures and surface cracks; (d) Pots should be arched to the highest temperature consistent with the refractoriness of the body.

摘要:

ABSTRACTThis paper gives the results of a metallographic investigation of some samples of defective white enameled ware, the peculiarities of the steel underlying the defects having been examined through the microscope. Two distinct kinds of defects were recognized, one of which, characterized by dark spots arranged in streaks, was found to be due to foreign inclusions in the steel. It was concluded that the other defect, consisting of irregularly scattered spots, was most probably due to gas absorption during pickling, the ultimate cause lying either with the pickling process or the steel quality. Detailed descriptions and photomicrographs are given of the structures and inclusions in the steel bases of the samples examined.
