Cutting a Figure


Book Description

Examining portraits of black people over the past two centuries, Cutting a Figure argues that these images should be viewed as a distinct category of portraiture that differs significantly from depictions of people with other racial and ethnic backgrounds. The difference, Richard Powell contends, lies in the social capital that stems directly from the black subject’s power to subvert dominant racist representations by evincing such traits as self-composure, self-adornment, and self-imagining. Powell forcefully supports this argument with evidence drawn from a survey of nineteenth-century portraits, in-depth case studies of the postwar fashion model Donyale Luna and the contemporary portraitist Barkley L. Hendricks, and insightful analyses of images created since the late 1970s. Along the way, he discusses major artists—such as Frédéric Bazille, John Singer Sargent, James Van Der Zee, and David Hammons—alongside such overlooked producers of black visual culture as the Tonka and Nike corporations. Combining previously unpublished images with scrupulous archival research, Cutting a Figure illuminates the ideological nature of the genre and the centrality of race and cultural identity in understanding modern and contemporary portraiture.




Pattern Cutting and Making Up


Book Description

Major changes have occurred in the last few years in the methods of cutting and manufacturing outerwear. Light clothing companies are now manufacturing these heavy garments because of the development of fusible interlinings and new manufacturing techniques which have resulted in the deskilling of traditional tailoring methods. Outerwear has consquently assumed much greater importance in light clothing courses and this book - the first of its kind - has been written to reflect these industrial changes. It offers a course of practical and theoretical study which is related to specific garment types and fabrics. An essential manual for students at every level. Suitable for use in CGLI, BTEC and degree courses, this uniquely comprehensive work is certain to become a standard textbook on its subject.

Faceting History: Cutting Diamonds and Colored Stones


Book Description

The author of, "FACETING HISTORY: CUTTING DIAMONDS AND COLORED STONES" has for a long time had a deep interest in learning how the early faceters (cutters) of diamonds and colored gemstones were able to complete their work. What methods did they use? What equipment did they have to make success possible? How soon did they discover how to complete the many phases necessary to accomplish their work? How did the equipment and methods differ between fashioning diamonds and faceting colored stones? These are just a few of the questions that the author wanted to find the answers for. In looking for answers to these and other questions, the author found that there were bits and pieces of information available in many previous books, but there was not a good book available that would answer most of his questions. Upon hearing the author ́s remarks about this fact, one of the librarians at the wonderful library located at the Gemological Institute of America ́s Carlsbad campus said that if such a book was not available, "maybe you should write the book!" Well, the author had been thinking of doing just that, but the remark caused the author to see the light and agree to get started on the project. Little did he know then that the project would require many months of eight hour days over seven day weeks to get the book completed. He decided to write a book that would answer these and other related questions that he had. The thought also occurred to him that such a book would be a valuable volume to be placed in libraries of individual faceters around the world. He realized that such a book would also be of great value to anyone who works behind a Jewelry store counter. A successful sales person is one who is knowledgeable about the products that they are selling. A book of faceting information would be extremely valuable if read and re-read from time to time. A customer in the Jewelry store will no doubt be favorably impressed by a sales presentation that is made with the use of interesting and informative information about diamonds and the various colored gemstones. The customer will be convinced that the sales person knows about what they are talking. The author has spent nearly three years on the project of researching the GIA library and other libraries, along with the extensive personal library of gemstone related books that he personally possesses. Many conflicting reports were noted in his study. He has made the statements in his book reflect the most commonly accepted opinions, of the most respected authors ́ works that he has found in his research. History is only obtainable from the earlier works of other authors. We cannot go back to the long past centuries ourselves, to see first hand what really happened and when it happened. A study of faceting history requires making the best choices of the information that is available. This completed book answers questions as to why the fashioning of diamonds was/is so different from the faceting of colored gemstones. The book compares the needed equipment and the methods that have brought the greatest successes. In addition, a great deal of other information connected to faceting is included. There are seven chapters in the book and there are over 125 photographs of the early equipment and methods that were used. The photographs show the faceters, the workroom conditions, and the tools and equipment that they used to complete beautiful and lasting gemstones. The book chapters are titled: An Introduction to Faceting, Early Man ́s Stone Appreciation, Diamond Fashioning Procedure and Equipment, Colored Stone Faceting Procedure and Equipment, The Evolution of Cut Designs, Famous and Historic Gemstones, Sources of Diamond and Colored Stone Rough, and lastly, Advances in Faceting Over the Past One Hundred Years. By books end, the reader will be well informed as to what is r

Metal Cutting Theory and Practice


Book Description

Metal cutting applications span the entire range from mass production to mass customization to high-precision, fully customized designs. The careful balance between precision and efficiency is maintained only through intimate knowledge of the physical processes, material characteristics, and technological capabilities of the equipment and workpieces involved. The best-selling first edition of Metal Cutting Theory and Practice provided such knowledge, integrating timely research with current industry practice. This brilliant reference enters its second edition with fully updated coverage, new sections, and the inclusion of examples and problems. Supplying complete, up-to-date information on machine tools, tooling, and workholding technologies, this second edition stresses a physical understanding of machining processes including forces, temperatures, and surface finish. This provides a practical basis for troubleshooting and evaluating vendor claims. In addition to updates in all chapters, the book features three new chapters on cutting fluids, agile and high-throughput machining, and design for machining. The authors also added examples and problems for additional hands-on insight. Rounding out the treatment, an entire chapter is devoted to machining economics and optimization.
