[876] Pickling Notes
Jewelers treat soldered objects with dilute acid solutions to remove oxides produced from heating and soldering as well as glassy flux residues. This process is called pickling. I believe the term comes from the chemical jewelers once used to do the job: Alum, such as is used traditionally for making pickles. Many jewelers today are not aware that they can use alum for this purpose. Here is what I think happened.... (2008)

[677] Pitch Bowls and Alternatives for Jewelers
Chasing and repousse is carried out on various surfaces using steel punches to strike and manipulate sheet metal or cast objects. Flat pattern chasing or stamping sheet metal can be done on an anvil, or the bottom of an old iron which makes an excellent surface to strike on. Sometimes thin double-sided carpet tape works well to stick a piece of metal onto a flat surface for stamping or chasing like this. Most chasing and repousse however has more dimensional relief than flat chasing and is often done with the metal fixed onto pitch. Various pitch types and hardnesses are available from most tool suppliers.... (2005)

[481] Practical Wax Modeling: Advanced Techniques for Wax Modelers
To begin with I highly recommend this book of technical information and procedures for anyone wanting to learn wax modelling techniques (as always given patience and practice in carrying out the exercises). There is very little available in English on jewellery oriented professional wax working and this text contributes to the field. A good half of the currently available books are by Japanese authors (Wada for instance). This is interesting when one considers that Japan did not have a tradition of precious metals jewellery using gems until after the Americans (and later DeBeers) introduced the concepts after World War II....

[521] Protecting Gems While Soldering
Repair jewelers are frequently called upon to solder close in to a set gemstone. Besides the normal dangers of heating a gem in these days of glass infills and other challenges it behooves a jeweler to keep a gemstone cool during soldering if at all possible. Remember Some 'Old-time' repair goldsmiths pride themselves on their speed using a mini-torch and they hold the set gem on a ring being sized in their fingers, going in very rapidly on the shank solder join with a pinpoint flame, so fast and hot that 'if your fingers get hot you were too slow'. While this method works with the right mini-torch and has a certain macho charm it does not fit every circumstance - and may lead to singed fingers..... (2002)

[162] Resumes and gallery presentation
The first questions to ask yourself when preparing a resume are: For whom is it intended? What do I want it to represent? Applying for a zoo keepers job you might put down your experience carrying llamas across the Andes but you would probably leave it out when apply for a position as a hair stylist. For galleries you should have information they will be interested in: previous exhibitions; articles on your work and so on that serve to establish you as a serious artist/craftsperson in their eyes....
