This document should be read in conjunction with the Act and Regulations which will govern. 1.1 Objectives of the Legislation The Act and Regulations seek: • to ensure that the information provided to consumers on the quality of a precious metal article is not misleading or deceptive; and • to provide for the uniform description and quality marking of precious metal articles, including jewellery, hollow ware, watches, spectacle frames, flatware, etc. in the Canadian marketplace thereby assisting consumers with their purchasing decisions. 1.2 Prohibitions Section 10 of the Act The Act prohibits: • a dealer from applying a mark to a plated article guaranteeing the durability or wear of the precious metal plating for a period of time. • a dealer from selling, importing into Canada or advertising any precious metal article in a manner which is false or misleading as to the precious metal content.

  • Improved Tarnish Resistant Sterling Silver
    Improved Tarnish Resistant Sterling Silver Michael T. Roche BHP Billiton, Townsville, Queensland, Australia Frank E. Goodwin International Lead Zinc Research Organization, Inc., Research Triangle Park, NC, USA Improved Tarnish Resistant Sterling Silver ABSTRACT A cooperative research program to determine means of delaying tarnishing of sterling silver has been organized by the Silver Research Consortium, a group of silver producers and users seeking to improve uses of silver by carrying out research. Whereas in the past most approaches to improving tarnish resistance have been based on silver alloying additions, this project is taking a scientifically based approach to reducing the rate of tarnishing by use of thin coatings. The general technical approach being taken and an overview of the Silver Research Consortium are given. INTRODUCTION: The principal sterling silver alloy, 92.5% Ag-5.7% Cu, has been used for silverware and jewelry since the 14th century. Alloying with copper strengthens silver and allows it to be used for these items, but it has always been susceptible to tarnishing. Tarnishing is a surface discoloration and mainly results from the formation of silver sulfide, Ag2S, although other compounds have been recently identified which contribute to tarnishing.[1,2] Although tarnishing is not important for industrial applications because it does not change the electrical or contact resistance properties of silver alloys, it is important for applications where appearance is important. Reflecting this importance, many attempts have been made over the years to develop tarnish-resistant alloys that meet the 92.5% silver purity standard which is required if the alloy is to be called “sterling silver.” Some of these have reached limited commercialization, but all add cost and complicate the manufacturing process for sterling silver.

The reality is thas prcdous - 3tals constitute also the base of several advanced materials used in the industry in hundreds of metric tom. Since forties, platinum alloys have been used as structural materials for quipments in the glass industry. The essential reason for this is the excellent resistance of platinum doys to oxidation and elcmolytical corrosion in molten glasses at temperatures as high as l2fX-LWC.

  • 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. Carbon 0.10 max. 0.10 max. Hydrogen 0.015 max. 0.015 max. Iron 0.25 max. 0.25 max. Oxygen 0.40 max. 0.40 max. Titanium Remainder Remainder Palladium –– 0.12 min.

  • Care and Cleaning of Silverplate & Sterling Silver Cutlery
    Care and cleaning of Silverplate & Sterling Silver Cutlery HANDWASHING Wash your cutlery in hot soapy water, using a sponge or nylon brush, as soon as possible after each use. Use a ‘mild’ detergent and avoid any containing lemon or vinegar. Rinse in hot water and dry thoroughly with a soft cloth. Do not allow to ‘air dry’. Store in dry conditions DISHWASHER Cutlery manufacturers recommend: DO NOT overload the cutlery basket. Pack cutlery with the handles down so that the knife blades, spoon bowls and fork tines are uppermost, ensuring that there is room for water to circulate. Separate knives from other cutlery components DO NOT mix metals, as different metals can ‘react’ with each other in the dishwasher, causing a stain ie: ensure that aluminium and stainless steel are separated from each other. Do rinse well as soon as possible after each use, before placing in dishwasher Do use correct quantities of dishwashing detergent and Rinse Aid as recommed by the dishwashing manufacturer. Detergent is highly chlorinated and can cause dulling and discolouration of stainless steel if excessive amounts are used. The long washing and drying cycles of dishwashers mean lengthy periods in humid conditions, which can encourage corrosion Do remove cutlery from the dishwasher as soon as possible after the cycle has finished and dry thoroughly with a soft cloth if water remains. Store cutlery in a dry environment Xylo or bone handled knives should NEVER be washed in the dishwasher. The handles should NEVER be placed in hot water as they will discolour POLISHING YOUR SILVERPLATE AND STERLING SILVER CUTLERY Tarnishing is the oxidation that occurs when silver comes in contact with acid foods such as Lemon, Vinegar, meat juices etc.

  • The Platinum/Palladium Process
    9 The Platinum/Palladium Process OVERVIEW AND EXPECTATIONS In the majority of the classes and workshops that I’ve taught over the years, “the platinum/palladium process” is the answer that surfaces first when I ask the question, “What process do you want to learn the most?” In this chapter you will learn how, and, as in previous chapters, I begin with a little history. Then you will learn the chemistry and sequence of the various stages to a finished print. This chapter gives you alternatives to traditional platinum/palladium chemistry and provides you with a simple sensitizer “drop chart” that is based on the type of negative you are working with, rather than the print you would like to make. I also provide the beginnings of a trouble-shooting list to assist in hunting down problems that may be showing up in your work. Finally, you’ll get some brief alternative ideas for combining platinum/palladium with other techniques such as Van Dyke and gum bichromate. A LITTLE HISTORY Like most refined non-silver and alternative photographic processes, the art of platinum/palladium printing was developed in pieces over time by a number of dedicated artists and scientists. In 1830, Ferdinand Gehlen recorded the action and effects of light on platinum chloride, noting that UV light would alter the color of platinum salts and cause the ferric salts to precipitate out into a ferrous state. At around the same time, Johann Wolfgang Dobereiner (1780–1849) observed the decomposition of ferric oxalate on exposure to UV light and scientifically defined its sensitivity.
