Z ., 6 [11] 5 i 3-75 (1954).--The esthetic value of a vessel depends on its suc cessful fulfillment of its practical purpose. The shape results SI from the considered sequence of the use of the ware, tlie ai list's personal idea of shape, his previous experience, and the effect of the raw material and its method of manipulation. An accord between shape, material, and the decoiation is essential. ' J-VS. How to make a platter. J ohn Kenny.

Gc. 31 [10] 329-36 (1954).--The megalithic ware of Lower Saxony and the RSssener ware are decorated with white or black cementitious fillings in incised patterns on the fired ware. The chemical an alyses of such fillings are recorded. The white materials can be divided into three groups, (1) a mixture of bone ash and quick lime (Springmuhie. Gdttingen). (2) essentially pure CaCO, (Mondsee), and (3) a mixture of white clay and CaCOj (Xacken- heira). A black filling consisted of wood charcoal bonded prob ably with casein (milk curds) adhesive. Accurate reproduc tions were made with a white filling of 1 part quicklime and S parts bone ash (hardened under moist conditions for3 to 4 weeks!, and a black filling of charcoal mixed with an adhesive of 1 part quicklime and 5 parts wet curds. There should be no difficulty in preparing colored filling materials.10 figures, 8 references. . J-4.S. Kachina dolls. Pec T ownsend.

D .J.b X IV -- General and Historical Bulk transportation by rail. J ohn M. Gleason. Am. Ceram. Soc. Bull., 34 [3] 72-73 (1955).--G. describes a new type of spedal hopper car for the efficient and economical shipment of dry pow dered and granular materials. Where materials are now being shipped in paper sacks, conversion to bulk shipment in the sew cars would effect substantial savings. 1 figure. Color in factories. C. StOrmer. Glas-Email-Kcramo-Tcch., 5 (12) 443-44 (1954).--A brief review is given of the psychological value of color, particularly of pastel shades, for both workrooms and machines. In choosing the colors, the effect of artitidal light must not be overlooked. It is recommended that moving pans of machines and hazardous sites in the workroom be painted yellow, and that the traditional bright red be retained for fire hazards. The use of colors to identify supply lines should be restricted to terminations (taps, valves), junctions, and patches spaced along the straight runs. J.A.S. Good design makes sense and dollars too.

Age, 63 |6) 25-27 (1954).--The merits of ceramic products are briefly described. Structural clavware, en ameled metals, refractories, chemical porcelain, electrical por celain, ferrites, titanates, etc., are covered. R.H.B. Perfect packing pays. H enry Bollman. Ceram. Ind., 62 [5J 65 (1954).--Packing of pottery for shipment is discussed. T.H.E. Which dusts in the ceramic and glass industries are a danger to health? K. G. S c h m id t . Ber. deul. teram. Ges., 31 111] 355-63 (1954).--Silicosis, its pathology, the factors contributing to its incidence, and the technique of atmospheric dust counting are reviewed. Disagreeable nasal aDd bronchial complaints are caused by the inhalation of SiO: particles >5p, but these particles are too large to enter the alveoles of the lung and therefore do not cause silicosis. The harmful particles are <5p, but a large pro portion of the very finest particles are expelled again with U* breath. Tridymite and cristobalitc are even more dangtroas than quartz (firebrick dust is therefore very harmful). Vitreous SiO: is harmless or almost so, and the silicate glasses are qtat* harmless. A mixture of coal and quartz dusts (around coal-fired kilns?) is particularly harmful; the addition of feldspar, mica, cc kaolin diminishes the effect of quartz dust, b u t it is uncertain whether mica dust alone is harmless. Clays are harmful accord ing to their free quartz content. Mixed dusts of quartz and fluorspar (in enamel plants) are particularly harmful. Pure corns, dum and silicon carbide are harmless, but asbestos and talc may / cause nonsilicotic fibrosis. Among other harmless dusts art olivine, augite, hornblende, gypsum, chalk, and Fe; the la tte gives shadows in the X-ray picture of the lung which may be mis taken for silicosis. Mention is also made of the health hazards occasioned by elements or compounds of Pb, As. Cr, Cd. Hg. S (in some mines), Mn, Zn, and Be. 11 figures, 39 references.
