Wrrkstattstech u .Vascbmenbau. 41 [3] 88-91 (1951); abstracted in Bibliot . Ind Diamond Applications, 8 (June) 330 (1951).--Definitions of grinding power, grinding effect, useful life, hardness of grinding heels, grinding time, abrasive material consumption, and grain disintegration are given. Difficulties arise when the quality of the grinding wheel is denoted by performance standards. When wheels of different makes are compared, the workpiece feed must oe kept constant. Economic working capacity is derived, and an estimation of grinding costs is attempted. These considerattons refer mainly to roughing, where the main objective is the re moval of a large quantity of material from the workpiece The Possibility of introducing a one-grade grinding wheel is discounted unless new abrasive materials can be produced with i hardness between that of silicon carbide and diamond or unless diamond prices are reduced. Qualities are compared, and the influence of working conditions is considered. 3 references, 2 illustrations. - Methods of testing abrasion and wear in the Netherlands. P. Braber and G. Salomon.

Bull., 1949, Xo. 7, pp. 12-17.--Underglaze blue designs on white porcelain ip-' peared In early Ming times, not as a new art but as a modified technique using a blue pigment instead of the black which had been common in Sung times for underglazc painting. Examples of what the authors think are the earliest recognizable types of blue and white are cited, and some details of the decoration are analyzed. 10 illustrations. IL Ibid., 1950, Xo. 9. pp. 40-50.-- Comments are made on P art I. It is proposed to call an un known artist of the Yuan to early Ming period "M aster of the David Vases." Several vessels attributed to this artist are de- so tb ed and illustrated as well as some copied in his manner. From evidence in the designs it is wmiwvt th a t the artist was probably a western painter working in China. Tbc significance and origin of the grape, melon, and morning glory as decorative motifs are discussed. 9 illustrations. F.RM .
