The symposium was organized by the Basic Science Section and held at Leamington Spa. October 14-10, 1903. M aterials considered include oxides, alkali halides, sullides, zeolites, alumino silicates, and graphite. The main divisions ol interest are the identification of individual defect centers, atom ic mobilitv in compounds, and'the mechanical properties largely dependent on point defects. Copies of the Proceedings are available at $9.00 each (SO.(10 to members) from the British Ceramic Society, Shelton House, Stoke Road. Shelton. Stoke-on-Trent, England. Peruvian Ceram ic Plant Proposed Manufacturing ceramic ware technical assistance by a United in Peru, under license States firm, is proposed bavnd Peruvian engineer, Sr. Hernan Arevalo del C vr>.. Va Sigerfoos of Michigan State University, who is in Peru as consultant fur the United States Agency for Internation t Development, reports there are deposits of kaolin and oth minerals for ceramics in the vicinity of Arequipa, Pery. second largest city. Plans are to form a company to man * facture sanitary ware, electrical insulators, chemical laf^ raton- equipment, ornam ental ware and other items no imported.

'' O w ens-Illinois Elects Executives The election of Edwin D. Dodd and Ebon C. Jones as executive vice-presidents of Owens-Illinois Glass Co. has been announced by R. H. Mulford, president. M r. Dodd, a vice-president of Owens-Illinois since 1959, is general manager of the company's Forest Products Division. Mr. Jones, also a company vice-president, is general m an ager of the Glass Container Division with responsibility for Owens-Illinois' domestic glass container and closure opera tions. The Division operates 17 glass container plants, three sand plants, three mold shops, three closure plants, a machine shop, an ink and die plant, and 52 sales branches. Glass Container and Forest Products are Owens-Illinois' two largest operating divisions. O . Hom m el A ssig n m en t to H epplew hite J. W. Hepplewhite is now associated with the O. Hommel Co., Pittsburgh, where he has been assigned to work in the area of pottery frits and glazes with responsibility for product development, customer service, and application techniques. He will report to William O. Brandt, the firm's technical director. An Em eritus M ember and Fellow' of The American Ceramic Society, Mr. Hepplewhite served as president in 1950-51. H e is affiliated with the Materials and Equipm ent Division and is also a member of the Founder's Group of the National In stitu te of Ceramic Engineers. . . . and Thailand Financial investm ent in a plant for producing kaolin a ceramic factory, refractories factory, calcium carbonate factory and an asbestos factory, is being sought by Soon thorn Thaviphoke, managing director of the United Thai Ceramic Mf.g Co., Ltd He may be addressed with requests for further details, a t 937 Sitthikasem, Somdej Road, Thon- buree, Thailand. y ,. ,- Pyroceram Hull for Deep-Sea Vehicle Pyroceram glass-ceramic by Corning Glass Works has beat chosen for the hull of Benthos, a deep-sea research vehicle. Chief designer for the project is J. D. Stachiw of Pennsylvania State University's Ordnance Research Laboratory, which is contracting Benthos for the U. S. Navy. The glass-ceramic hull will be completed in 1905. About S ft long and 1 ft in diameter, the unmanned vehicle will consist of four glass-ceramic cylindrical sections and a metal stabilizer section, joined by special locking rings. Benthos is expected to have a buoyancy of about 60% of the displaced water. It is designed to have a payload capability of 100 to 150 pounds at a depth greater than 30,000 ft. . .; Pyroceram glass-ceramic was chosen as the hull material primarily because of its compressive strength, which is higher than 300,000 psi. Corning said the theoretical strength-toweight ratio of the glass-ceramic is higher than th a t of high strength aluminum and steel alloys now used for underwater vehicles. International Minerals & Chemical Corporation Builds Research Center Construction has started on the new $0 million Research and Development Center of International Minerals & Chemical Corp., in Libertvville, 111. Research projects will include work in ceramics, glass, agricultural, animal feed, foundry, and food industries. Initial empluvmenl at the center will be 900. The center, on a 397-acre site at US 45 and W inchester Road, is expected to be completed in late 1905. It will have more than 170.00(1 square feet of space, along with experimental plots. It will consist of a one-story otlice building, built around a center courtyard; a three-story research and development laboratori- building; a development en gineering building; two large greenhouses with connecting head house; four farm buildings, and a central utility building. 6S4 C eram ic B ulletin Nominations for Officers, 1965--66 The American Ceramic Society President-Elect: George J.
