STUDY OF GLAZE AND BODY INTERFACE*

Lead-containing raw glazes were applied on biscuit tile and fired at cones 02, 2, and 4. The glaze body interface was examined microscopically by preparing thin cross sections. The powdered glassy portion was also investigated. Because the crystals separating at the interface were frequently too small for satisfactory study, a technique for promoting their growth was used. Anorthite, wollasto-nite, gehlenite, undissolved quartz, tridymite, and cristobalite were observed. The effects of altering the bases and the alumina and silica content of the glaze were studied, and the amount and the effect of the solution of the body were examined. The authors conclude that the interfacial layer is not necessarily intermediate in expansion conduct.

FUNDAMENTAL STUDY OF CLAY: IV,SURFACE AREA AND ITS EFFECT ON EXCHANGE CAPACITY OF KAOLINITE*

Six monodisperse fractions of kaolinite were prepared, and the exchange capacity was determined from the viscosity relations on additions of NaOH to the electrodialyzed fractions. A linear relationship is shown to exist between the surface area and the base-exchange capacity for all of the sizes studied.     

SURFACE TENSION OF GLASS AND ITS EFFECT ON CORDS*

The results of experiments with synthetic cords indicate that surface tension is the most important factor in the disappearance of cords. The viscosity relations of the glasses do not correlate with the tendency to form inhomogeneities. Fibers of higher surface tension than the base glass with which it is fused form cords, and those of lower surface tension do not. Compositions that are high in RO or A1208 tend to form inhomogeneities in glasses which have a lower content of these two constituents.     

INFLUENCE OF GLAZE ON STRENGTH OF STEATITE TUBES AND NEW METHOD OF DETERMINING GLAZE STRESSES *

Different glazes have been applied on steatite tubes and the influence on impact and flexural strength has been investigated. Glazes applied on tubes with very thin walls affect the thermal expansion of the ceramic body. This fact has been used to test the glaze fit.

ZINC-VAPOR GLAZING OF CLAYS: II,EFFECT OF VARIABLE LIME AND ALKALIS IN CLAYS ON ZINC-VAPOR GLAZE COLORS*

A study was made of the influence of the lime content of brick on their ability to take zinc-green, yellow, tan, and brown glazes. Desirable greens were obtained with clays containing as much as 3% lime; those with a higher percentage of lime generally produced yellow-greens. The probability of obtaining good greens was best on clays with more than 6% of alkalis when their absorptions after firing were below 2%. Desirable greens were not obtained on bodies which had absorptions greater than 6.7%. Firing under oxidizing conditions before flashing and slow cooling tended to promote the formation of desirable brown, tan, and straw-colored zinc-vapor glazes.
