ABSTRACTSodium aluminate has been used as a water‐softening agent, but not to any great extent in the ceramic industry. The results of this investigation show that sodium aluminate when used as a substitute for sodium carbonate in casting slips eliminates or minimizes some of the troubles usually encountered in the control of slips and in casting war

摘要:

ABSTRACTThe paper describes a new apparatus for measuring glass viscosities of 1013poises and higher. It consists of causing the glass flow to take place inside a steel tube by means of air pressure. The amount of flow is observed by means of interference fringes between the top of the glass sample and a stationary plate of fused silica. Preliminary experiments with two glasses, a lime and a light flint, are described and the results given. A comparison is also made between results by this method and by that of fiber elongation. The new results indicate that the apparatus can he successfully used for observing flow‐pressure relations at extremely high viscosities and also that at the temperatures used these two glasses are purely viscous liquid

摘要:

ABSTRACTThe reason for variability of tests for physical properties of porcelain enamel was investigated. Slight differences in gage of base metal, its source and method of manufacture, and the fineness and thickness of the enamel coating and firing temperature all seriously affect the results obtained. These physical properties may be adjusted at will by regulating the method of preparation.

摘要:

ABSTRACTA discussion of the properties required by oil for kiln‐car lubrication is presented. The results reported on questionnaires answered by forty plants operating tunnel kilns are given, together with comments and conclusions therefrom. The residue, flash, and burning points of ten different oils approved for kiln‐car lubrication are listed with directions for using oil as a lubricant on tunnel kiln c
