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. -

Antibacterial Property and Biocompatibility of Silver, Copper, and Zinc in Titanium Dioxide Layers Incorporated by One-Step Micro-Arc Oxidation: a Review
antibiotics Review Antibacterial Property and Biocompatibility of Silver, Copper, and Zinc in Titanium Dioxide Layers Incorporated by One-Step Micro-Arc Oxidation: A Review Masaya Shimabukuro Department of Biomaterials, Faculty of Dental Science, Kyushu University, 3-1-1 Maidashi, Higashi-ku, Fukuoka 812-8582, Japan; [email protected]; Tel.: +81-92-642-6346 Received: 3 October 2020; Accepted: 19 October 2020; Published: 20 October 2020 Abstract: Titanium (Ti) and its alloys are commonly used in medical devices. However, biomaterial-associated infections such as peri-implantitis and prosthetic joint infections are devastating and threatening complications for patients, dentists, and orthopedists and are easily developed on titanium surfaces. Therefore, this review focuses on the formation of biofilms on implant surfaces, which is the main cause of infections, and one-step micro-arc oxidation (MAO) as a coating technology that can be expected to prevent infections due to the implant. Many researchers have provided sufficient data to prove the efficacy of MAO for preventing the initial stages of biofilm formation on implant surfaces. Silver (Ag), copper (Cu), and zinc (Zn) are well used and are incorporated into the Ti surface by MAO. In this review, the antibacterial properties, cytotoxicity, and durability of these elements on the Ti surface incorporated by one-step MAO will be summarized. This review is aimed at enhancing the importance of the quantitative control of Ag, Cu, and Zn for their use in implant surfaces and the significance of the biodegradation behavior of these elements for the development of antibacterial properties. Keywords: titanium; biofilm; infection; micro-arc oxidation; silver; copper; zinc; antibacterial properties; coating; implant 1. -
Titanium Alloy Data Sheet
M Titanium Alloy Data Sheet Description Titanium equipment is often used in severe corrosive environments encountered in the chemical processing industries. Titanium has been considered an exotic “wonder metal” by many. This was particularly true in reference to castings. However, increasing demands and rapidly advancing technology have permitted titanium castings to be commercially available at an economical cost. The combination of its cost, strength, corrosion resistance, and service life in very demanding corrosive environments suggest its selection in applications where titanium castings have never been considered in the past. Specifications Flowserve’s commercially pure titanium (C.P.-Ti) castings conform to ASTM Specification B367, Grade C-3. Flowserve’s palladium stabilized titanium (Ti-Pd) castings conform to Grade Ti-Pd 8A. Composition C.P.-Ti (C-3) Ti-Pd (8A) Element Percent Percent Nitrogen 0.05 max. 0.05 max.

Gilt Fibula with Christogram from Imperial Palace in Sirmium

Ornament on the foot enclosed within rectangular field is executed in the niello technique. End of the foot is bent at the right angle and the Christogram is engraved on it with Greek letters alpha and omega engraved above its side arm. The preserved part of fibula makes possible reconstruction of its appearance and attribution to the group of massive bronze crossbow fibulae, which were produced in the second half of the 4th century and characterized by decoration consisting of gilding, niello, Christogram motif and/or the busts of young men in medallions.

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.
