TECHNICAL REPORT: Continuous Casting of Jewellery Alloys
This report concerns the technology of continuous casting of the precious metals, primarily for jewellery and related usage. It covers a number of aspects:
• Principle of solidification
• Practice of continuous casting
• Factors affecting the process and product quality
• Further processing of continuously cast product
• Specific jewellery alloys: best practice
• Commercial equipment
• List of manufacturers
• Further reading and references
The commercial and technical advantages of continuous casting will be highlighted and some of the problems that can arise will be discussed. Who can best benefit from use of this technology – alloy suppliers, jewellery manufacturers, etc - is another aspect that is addressed.

TECHNICAL REPORT: Tungsten Inert Gas (TIG) Welding for Silversmiths
It is rare to be able to identify an affordable, effective and simple technology that has so much potential for silversmiths and offers an exciting alternative to traditional joining technologies. Tungsten inert gas (TIG) welding is an arc welding process in which an arc is formed between a pointed tungsten electrode and the workpiece in an atmosphere of inert gas. The small intense arc provided by the pointed electrode is ideal for high quality and precision welding. By controlling the heat input, weld can be made over a wide range of materials and thickness from thin sheets less than 0.1mm thick to large plates in excess of 10mm. This report is written by silversmith Hector Miller in conjunction with The Welding Institute (TWI) and offers a practical overview of the incorporation of a TIG welding facility into a silversmithing workshop.

TECHNICAL REPORT: An Introduction to (CAD) for the Jewellery and Silversmithing Industry
We have become increasingly aware of the need for a technical report that demystifies the Computer Aided Design (CAD) process and its associated terminology. Even those of us who have a little knowledge in relation to the subject are still often baffled by the terms used by the salesmen who wish to encourage us to take on board their particular product. This report will provide the reader with a basic guide to which they can refer when faced with this situation and allow them to ask the pertinent questions that will allow them to arrive at a meaningful decision when considering purchasing software.

MARKET REPORT: The US Jewellery Market - Export Potential for UK Companies
This report was commissioned by The Worshipful Company of Goldsmiths (WCG) as part of an effort to generate strategic insight and direction within the UK jewellery industry, as recommended in a report published by the Department of Trade and Industry in 2002.
Whilst this report is primarily aimed at UK manufacturers interested in the opportunity of exporting to the US market, it should also provide useful insight for anyone associated with and/or interested in the US jewellery industry. As such, the main purpose of the report is to clearly map out the structure of the US jewellery market with the British manufacturing viewpoint in mind. Consequently, the report makes observations and recommendations to UK companies assessing the opportunity in the US market, and provides useful information for companies keen to pursue their interest in this market further.
Price: This report has been heavily subsidised by the Goldsmiths' Company and is available at £25 in CD(PDF) or £50 printed format (Includes UK postage) |

TECHNICAL REPORT: Rapid-Prototyping Applications for the Jewellery & Silversmithing Industries
Rapid-Prototyping is a technique for the production of solid objects from computer models. The variety of Rapid-Prototyping devices and materials that can be processed is increasing all the time. In this paper the authors examine the historical development of this technology and the potential for the application of current devices and materials to jewellery and silversmithing workshop practices now and in the future.

TECHNICAL REPORT: Laser Spot Welding. Technical guidelines and innovative applications for the jewellery industry
The first of a new series of technical reports commissioned and produced by the Technology & Training Department.
This guide sets out to explain some of the opportunities, issues and attributes of laser spot welding and its specific application to the jewellery and silversmithing industry. Demystifying the technology by avoiding jargon, it highlights health and safety issues and provides an overview of key maintenance requirements for the equipment used. Importantly, it will provide a workshop resource containing quick reference sections as well as in-depth guidance for users of the technology.

TECHNICAL REPORT: Small Scale Silver Refining
ABSTRACT:
A batch process for the refining of silver from impure scrap is described with non-technical step-by-step instructions. The method works well for quantities up to about 5 or 6 kilos (and quite likely more if larger containers are used). Purity of refined silver is normally above 999 and with special care 9999 is possible. A list is given of the equipment and supplies required. The simple safety and procedural precautions are described as are the few necessary control tests. Some suggestions for pollution control are discussed.

TECHNICAL REPORT: Tarnish Resistant Silver - A Summary of Five Years' Research at Birmingham University
The purpose of this report is to provide an over-all summary of the work completed, and so enable a realistic assessment of the prospects for producing a commercially viable tarnish-resistant silver alloy. The research has fallen into three clear phases, A. The establishment of a procedure for testing tarnish-resistance, B. The synthesis of possible tarnish-resistant alloys by conventional metallurgy and C. The synthesis of such alloys by electro-deposition. The research work summarised in this report was carried out in the Department of Metallurgy and Materials Science, The University of Birmingham, under the guidance of Dr. JPG Farr, between October 1977 and September 1983.

TECHNICAL REPORT: The Recovery of Gold from Jewellery Sweeps
This paper reports on how the jeweller's precious metal wastes can be prepared, sampled and assayed for dispatch to the refiner. In other words how to make out a reasonably accurate 'deposit slip' for this valuable scrap. The method(s) here described are certainly not the only ones, but have been used with reasonable success by the author over many years.

TECHNICAL REPORT: Small Scale Gold Refining
This paper is a description of refining methods for gold as eveloved over a ten-year period of part-time but very regular work. The author is a graduate chemical engineer and a jeweller and the refining was at first self-taught. After some months of experience the book "Refining Precious Metal Wastes" by CM Hoke was discovered. This confirmed most of the work, answered some questions and added much to the investigator's knowledge. Since then research has resulted in changes in some methods and a very large reduction in the time needed to process a batch of scrap.

TECHNICAL REPORT: The R T Blanking System
ABSTRACT: A technique of making blanking tools for sheet metal and other materials is described in detail. The technique requires only the normal tools and skills of the jewellery or silversmithing craftsman to produce tools for theblanking of large or small quantities of simple or complex forms.
The tools produced are suitable for use in conventaional hand or foot presses or can even be used in a bench vice or with simple hammer blows. Special equipment developed to facilitate production and usage of the tools is also mentioned. This report is a detailed description of a very low-cost method of making blanking tools for sheet metal and other materials using the normal skills and tools of the jewellery or silversmithing craftsman.
