The original intention was to have three presentations in the series "An Introduction to Metallurgy." These have been "The Nature of Metals and Alloys," "Solidification and Casting" and "Working, Annealing and Deformation Processes." It is evident that some metallurgical topics of interest to silversmiths and jewelers do not fit readily under these three headings. Consequently, there were some omissions. The aim of this presentation is to redress that by highlighting the metallurgical principles and mechanisms underlying three such topics, namely, "Soldering and Brazing," "Corrosion and Stress Corrosion" and "Tarnishing." Papers have been given at past Symposia on practical aspects of these topics with respect to jewelry manufacturing technology. Here, the emphasis is on promoting an understanding of the theoretical background.
