Repousse Work for Amateurs. : REPOUSSE WORK FOR AMATEURS: BEING THE ART OF ORNAMENTING THIN METAL WITH RAISED FIGURES. tfjLd*- 6 By L. L. HASLOPE. ILLUSTRATED. LONDON L. UPCOTT GILL, 170, STRAND, W.C, 1887. PRINTED BY A. BRADLEY, 170, STRAND, LONDON. 3W PREFACE. " JjJjtfN these days, when of making books there is no end," ^*^ and every description of work, whether professional or amateur, has a literature of its own, it is strange that scarcely anything should have been written on the fascinating arts of Chasing and Repousse Work. It is true that a few articles have appeared in various periodicals on the subject, but with scarcely an exception they treated only of Working on Wood, and the directions given were generally crude and imperfect. This is the more surprising when we consider how fashionable Repousse Work has become of late years, both here and in America; indeed, in the latter country, "Do you pound brass ? " is said to be a very common question. I have written the following pages in the hope that they might, in some measure, supply a want, and prove of service to my brother amateurs. It has been hinted to me that some of my chapters are rather "advanced;" in other words, that I have gone farther than amateurs are likely to follow me. -

Taylor Submitted to the Department of Materials Science and Engineering on May 3, 2013 in Partial Fulfillment of the Requirements for the Degree of Bachelor of Science in Archaeology and Materials ABSTRACT In both the Andean zone of South America and in Mesoamerica, copper-silver alloys were important in the production of thin, silver-colored sheet metal artifacts. This thesis examines the mechanical and physical properties of the copper-silver alloy system that are important to understanding why copper-silver alloys became central to the metallurgies that developed among prehistoric societies of the Andean zone and Western Mexico. These properties include their range of malleability, the microstructures behind their toughness, and the recrystallization and annealing behaviors that led to their development of silver-enriched surfaces. To determine these properties, a series of cold rolling, cold hammering, and annealing experiments were performed on five Cu-Ag alloys and pure copper. -

The Platinum Group Metals As Coating Materials
Issue No. 38 – February 2012 Updated from Original August 2002 Publication The Platinum Group Metals as Coating Materials How precious is your metal - An overview on The platinum group metals consist of platinum and palladium, as well as rhodium, iridium, the use of the platinum osmium, and ruthenium. They can be found in the transition metals on the periodic table of the elements. A close-up of this part of the table is shown in Figure 1. Palladium is currently the group metals as contact surfaces for electronic only metal of the group in widespread use in electrical contacts, although platinum was widely connectors. used in the past. Rhodium is only used in electrical contact applications requiring very high hardness and wear resistance. The other three metals in the group are used mainly in other industrial applications. Pure, electroplated platinum and palladium have a hardness of around 200 to 400 HV, although . Platinum they may also be applied by cladding. Both have a conductivity of around 16% IACS. Thus they are harder than gold, but slightly less conductive. At one time, their prices were . Palladium competitive with gold, and gold-flashed palladium coatings were even used as less expensive alternatives to gold coatings. However, both of these metals are much more expensive than gold . Rhodium (at least at the time of this writing). Due to its cost, gold-flashed palladium is now used mainly in applications which require greater hardness and wear resistance than hard gold alone. Ruthenium Rhodium is much harder than platinum and palladium, typically 800-1000 HV, with an . -
