A Very British Family

A Very British Family PDF Author: Laura Trevelyan
Publisher: Bloomsbury Publishing
ISBN: 085773363X
Category : Biography & Autobiography
Languages : en
Pages : 322

Book Description
It is a rule that no Trevelyan ever sucks up either to the press, or the chiefs, or the “right people”.The world has given us money enough to enable us to do what we think is right. We thank it for that and ask no more of it, but to be allowed to serve it.' G. M. Trevelyan The Trevelyans are unique in British social and political history: a family that for several generations dedicated themselves to the service and chronicling of their country, from the radical, reforming civil servant Charles Edward Trevelyan to the historian G. M. Trevelyan. Often eccentric, priggish, high-minded and utterly self-regarding, they have nonetheless left their mark on our past. This engaging history dispassionately explores the lives and achievements of this unique family and the part they played in shaping the history of Great Britain.

18th and 19th Century Porcelain Analysis

18th and 19th Century Porcelain Analysis PDF Author: Howell G. M. Edwards
Publisher: Springer Nature
ISBN: 3030421929
Category : Technology & Engineering
Languages : en
Pages : 344

Book Description
This book addresses the contributions made by analytical chemistry to the characterisation of 18th and early 19th Century English and Welsh porcelains commencing with the earliest reports of Sir Arthur Church and of Herbert Eccles and Bernard Rackham using chemical digestion techniques and concluding with the most recent instrumental experiments, which together span more than a hundred years of study. From the earliest experiments which required necessarily the sacrifice of significant portions of each specimen, which may already have been damaged , to the latest experiments which needed only microsampling or the non-destructive interrogation of valuable perfect specimens a comprehensive survey is undertaken of more than twenty manufactories of quality porcelains. The correlation is made between the quantitative elemental oxide determinations of the scanning electron microscopic diffraction and Xray fluorescence data and the qualitative molecular spectroscopic Raman data to demonstrate their complementarity and use in the holistic forensic assessment of the origin of the fired procelains ; this will form the groundwork for the adoption of analytical techniques for the attribution of unknown or questionable procelains to their potential source factories . The book will also examine the perception of what constitutes a porcelain and its definitions and examines the assignment of porcelains to types which currently employs the definitions of hard paste , soft paste , hybrid , magnesian and bone china from the conclusions derived from the analytical data and a consideration of the raw materials employed in their manufacturing processes. During the discussion of this analytical evidence several themes and protocols have been established for its utilisation in the potential identification of porcelains and several case studies undertaken for this purpose are cited. The book will be of interest to analytical scientists , to museum ceramics curators and to ceramics historians.

Plant Engineer's Handbook

Plant Engineer's Handbook PDF Author: R. Keith Mobley
Publisher: Elsevier
ISBN: 0080539041
Category : Technology & Engineering
Languages : en
Pages : 1203

Book Description
Plant engineers are responsible for a wide range of industrial activities, and may work in any industry. This means that breadth of knowledge required by such professionals is so wide that previous books addressing plant engineering have either been limited to only certain subjects or cursory in their treatment of topics. The Plant Engineering Handbook offers comprehensive coverage of an enormous range of subjects which are of vital interest to the plant engineer and anyone connected with industrial operations or maintenance.This handbook is packed with indispensable information, from defining just what a Plant Engineer actually does, through selection of a suitable site for a factory and provision of basic facilities (including boilers, electrical systems, water, HVAC systems, pumping systems and floors and finishes) to issues such as lubrication, corrosion, energy conservation, maintenance and materials handling as well as environmental considerations, insurance matters and financial concerns. One of the major features of this volume is its comprehensive treatment of the maintenance management function; in addition to chapters which outline the operation of the various plant equipment there is specialist advice on how to get the most out of that equipment and its operators. This will enable the reader to reap the rewards of more efficient operations, more effective employee contributions and in turn more profitable performance from the plant and the business to which it contributes.The Editor, Keith Mobley and the team of expert contributors, have practiced at the highest levels in leading corporations across the USA, Europe and the rest of the world. Produced in association with Plant Engineering magazine, this book will be a source of information for plant engineers in any industry worldwide.* A Flagship reference work for the Plant Engineering series* Provides comprehensive coverage on an enormous range of subjects vital to plant and industrial engineer* Includes an international perspective including dual units and regulations

The Spectroscope and Gemmology

The Spectroscope and Gemmology PDF Author: Basil Anderson
Publisher: Robert Hale
ISBN: 9780719803215
Category : Absorption spectra
Languages : en
Pages : 0

Book Description
Until 1933, the refractometer and the microscope were the two principal tools in gem testing. Then B.W. Anderson introduced the hand spectroscope which quickly became the third vital instrument for the UK gemmologist. Anderson and his lifelong colleague, Payne, both of the world's first full-time gemmological laboratory, were the pioneers in recognizing the vast potential of the spectroscope, and The Spectroscope and Gemmology is the extensively edited, updated, and enlarged version of Anderson's original papers. The distinguished gemmologist R. Keith Mitchell undertook the editing and added of chapters on the Pye spectrophotometer and on lasers. He also reproduced new line drawings of spectra in three aspects to accommodate the prism instrument in both the British version and in that favored by American gemmologists, and in another version as seen through the diffraction grating instrument.

The Tastemakers

The Tastemakers PDF Author: Diana Davis
Publisher: Getty Publications
ISBN: 1606066412
Category : Art
Languages : en
Pages : 322

Book Description
An examination of the development, role, and influence of the British decorative art dealers who invented an Anglo-Gallic style for elite interiors. In this volume Diana Davis demonstrates how London dealers invented a new and visually splendid decorative style that combined the contrasting tastes of two nations. Departing from the conventional narrative that depicts dealers as purveyors of antiquarianism, Davis repositions them as innovators who were key to transforming old art objects from ancien régime France into cherished “antiques” and, equally, as creators of new and modified French-inspired furniture, bronze work, and porcelain. The resulting old, new, and reconfigured objects merged aristocratic French eighteenth-century taste with nineteenth-century British preference, and they were prized by collectors, who displayed them side by side in palatial interiors of the period. The Tastemakers analyzes dealer-made furnishings from the nineteenth-century patron’s perspective and in the context of the interiors for which they were created, contending that early dealers deliberately formulated a new aesthetic with its own objects, language, and value. Davis examines a wide variety of documents to piece together the shadowy world of these dealers, who emerge center stage as a traders, makers, and tastemakers.
