| [495] Optimising Gold Alloys for the Manufacturing Process |
Standard yellow gold alloys which are based on gold-silver copper can be used for many production processes. They could be called ‘all-purpose’ alloys. However, optimising the alloys for the particular manufacturing process to be employed is possible by use of other alloying additions which can influence relevant properties such as castability and grain size as well as the mechanical ones, for example, strength, hardness and ductility. Only a few elements (e.g. zinc, silicon, iridium, cobalt) have proved to be useful additions for modifying carat gold alloys without detrimentally changing other relevant properties.... (2002)

| [861] Palladium Chain Making Using Mass Production Methods |
As proudly proclaimed in its name, Balestra 1882 has manufactured high quality gold and platinum chain in Italy since 1882. Now a global organization, its operations have extended far beyond the city of its birth. Last fall, they started researching palladium alloys for jewelry and have begun manufacturing palladium chain. Currently, they offer over 25 different styles of palladium chain in a variety of weights, and sizes. Their factory is capable of processing precious metals from bullion to finished product. Presented here is an overview of their chain manufacturing processes at their facility in Bassano Del Grappa, Italy.... (2007)

| [335] Platinum - Machines, Hands and Wedding Bands |
If you have never manufactured with platinum and you think that you are ready, if you manufacture with platinum, but you have not capitalized on the growing potential of the bridal market, even if you are successful at manufacturing platinum bridal jewelry, I hope some of what is contained in this paper will be of help to you. I have been involved in wedding ring manufacturing for about 25 years. For the last eight years, I have committed a majority of my time to designing in platinum, and platinum and 18-karat gold combinations. I have always looked at my designing successes in our industry and equated them with my desire to explore. As a result of my last decade of studying, platinum and I have become great friends....

| [487] Practical Guide to Mass Finishing of Precious & Costume Jewelry: Methods and Myths |
A microscopic and technical view of mass finishing presented in layman's terms. Understanding of mass finishing must start at the very basic level of what happens microscopically to the surface of various materials. All the variables will be discussed, such as the media, compounds and the effect of various types of machinery on the finishing process. Practical techniques and the associated costs will be presented for pre-finishing of precious metal jewelry as well as costume or imitation jewelry. This article is an explanation of Mass Finishing from a practical standpoint.... (2004)
