The Care and Preservation of Historical Silver by CLARA DECK, CONSERVATOR REVISIONS by LOUISE BECK, CONSERVATOR
The Care and Preservation of Historical Silver BY CLARA DECK, CONSERVATOR REVISIONS BY LOUISE BECK, CONSERVATOR Introduction Historical silver can be maintained for years of use and enjoyment provided that some basic care and attention is given to their preservation. The conservation staff at The Henry Ford have compiled the information in this fact sheet to help individuals care for their objects and collections. The first step in the care of all collections is to understand and minimize or eliminate conditions that can cause damage. The second step is to follow basic guidelines for care, handling and cleaning. Most people know that silver is a white, lustrous metal. Pure or “fine” silver is called “Sterling” if it is made up of no less than 925 parts silver to 75 parts alloy. Sterling will thus often have ‘.925’ stamped somewhere on it, as an identifier. Silver objects, especially coins and jewelry, contain copper as an alloying metal for added hardness. The copper may corrode to form dark brown or green deposits on the surface of the metal. Silver is usually easy to differentiate from lead or pewter, which are generally dark gray and not very shiny. Silver is often plated (deposited) onto other metallic alloys, almost always with an intermediate layer of copper in between. The earliest plating process, “Sheffield Plate” was developed in England in 1742. By the mid-19th century, the process was largely replaced by electroplating (which used less silver). The base metal in plated artifacts may consist of any of the following metals or alloys: copper, brass, “German silver” or “nickel silver” (50% copper, 30% nickel, 20% zinc), “Brittania metal” (97% tin, 7% antimony, 2% copper), or a “base” silver containing a high percentage of copper. -
The Economic Development of Sheffield and the Growth of the Town Cl740-Cl820
The Economic Development of Sheffield and the Growth of the Town cl740-cl820 Neville Flavell PhD The Division of Adult Continuing Education University of Sheffield February 1996 Volume One THE ECONOMIC DEVELOPMENT OF SHEFFIELD AND THE GROWTH OF THE TOWN cl740-c 1820 Neville Flavell February 1996 SUMMARY In the early eighteenth century Sheffield was a modest industrial town with an established reputation for cutlery and hardware. It was, however, far inland, off the main highway network and twenty miles from the nearest navigation. One might say that with those disadvantages its future looked distinctly unpromising. A century later, Sheffield was a maker of plated goods and silverware of international repute, was en route to world supremacy in steel, and had already become the world's greatest producer of cutlery and edge tools. How did it happen? Internal economies of scale vastly outweighed deficiencies. Skills, innovations and discoveries, entrepreneurs, investment, key local resources (water power, coal, wood and iron), and a rapidly growing labour force swelled largely by immigrants from the region were paramount. Each of these, together with external credit, improved transport and ever-widening markets, played a significant part in the town's metamorphosis. Economic and population growth were accompanied by a series of urban developments which first pushed outward the existing boundaries. Considerable infill of gardens and orchards followed, with further peripheral expansion overspilling into adjacent townships. New industrial, commercial and civic building, most of it within the central area, reinforced this second phase. A period of retrenchment coincided with the French and Napoleonic wars, before a renewed surge of construction restored the impetus. -

The Techniques and Material Aesthetics of the Daguerreotype
The Techniques and Material Aesthetics of the Daguerreotype Michael A. Robinson Submitted for the degree of Doctor of Philosophy Photographic History Photographic History Research Centre De Montfort University Leicester Supervisors: Dr. Kelley Wilder and Stephen Brown March 2017 Robinson: The Techniques and Material Aesthetics of the Daguerreotype For Grania Grace ii Robinson: The Techniques and Material Aesthetics of the Daguerreotype Abstract This thesis explains why daguerreotypes look the way they do. It does this by retracing the pathway of discovery and innovation described in historical accounts, and combining this historical research with artisanal, tacit, and causal knowledge gained from synthesizing new daguerreotypes in the laboratory. Admired for its astonishing clarity and holographic tones, each daguerreotype contains a unique material story about the process of its creation. Clues from the historical record that report improvements in the art are tested in practice to explicitly understand the cause for effects described in texts and observed in historic images. This approach raises awareness of the materiality of the daguerreotype as an image, and the materiality of the daguerreotype as a process. The structure of this thesis is determined by the techniques and materials of the daguerreotype in the order of practice related to improvements in speed, tone and spectral sensitivity, which were the prime motivation for advancements. Chapters are devoted to the silver plate, iodine sensitizing, halogen acceleration, and optics and their contribution toward image quality is revealed. The evolution of the lens is explained using some of the oldest cameras extant. Daguerre’s discovery of the latent image is presented as the result of tacit experience rather than fortunate accident. -

Accordingly this volume appears as a complementary and companion volume to that on " Old Silver," and although the former describes the history and character of the silver- smiths' work from Elizabeth to Victoria, the present volume covers a much shorter period, approximately a hundred years, when the plater's skill, in what is now generally known as old Sheffield Plate, of superimposing a thin sheet of silver on a copper base, won a triumph in the great art of simulation until it was superseded by the modern electro-plating process. -
