Triaxial Porcelain. These compositions are compounded from mixtures of feldspars, kaolinite clays, and flint. Table 1.6 shows the range of compositions and formulations they utilize. Table 1.7 hsts the ranges of electrical, thermal, and mechanical properties of low- and high-voltage triaxial porcelains. They exhibit fairly low mechanical strength and... 

Seven different layers were exposed during the excavations, three of which provided substantial amount of fossils the upper yellowish stratum, the dark-brown layer with limestone rubble ( Upper layer of fireplace ) and the light-brown cave clay with fine rubble ( lower layer of fireplace ). The two above-mentioned cultural strata contained a rich material of chipped flint implements of Aurignatian type. Since the faunal remains of the various layers differ only in percentile composition, rather than fundamentally, I present the faunal list without numbers of specimens. The following composition of the fauna is based on Jfinossy (1955) (the cave bear was dominant by far, over 15,000 finds) ... 

Deformation Eutectic. The composition within a ceramic system (e.g. china clay, flint and feldspar) which, when heated under specified conditions, deforms at a temperature lower than that required to produce deformation in any other... 

Mason s Ironstone China. A vitrified type of earthenware introduced by C. J. Mason, Stoke-on-Trent, England. According to his patent (Brit. Pat. 3724, 1813) the batch composition was 4 pts. china clay, 4 pts. china stone, 4 pts. flint, 3 pts. prepared ironstone, and a trace of cobalt oxide. It is now known that the body did not contain ironstone, the name merely being a highly successful method of indicating to the public that the ware was very strong. 

Ceramic compositions forming the basis for the whiteware industry are the mixtures of clay, feldspar, and flint. These compositions include hard porcelain for tableware, sanitary ware, electrical porcelain, and so on.
