Thomas, you are misled.  Gold is the only metal that does NOT oxidize.  You can change the states of the metal, i.e. solid to liquid.  Temperature, during the  melting process, DOES NOT OXIDIZE the gold.  Gold DOES NOT OXIDIZE . . .PERIOD.  Why do you think the use it for a coating on contacts in computers and associated hardware??  Because it NEVER OXIDIZES.



Hope this clears up some misinformation for you.

Jerry, Thomas is correct, gold does oxidize around and above it's melting point, therefore it is essential to use borax as stated..

Gold is very stable at temperatures normally found in electronic devices and equipment, hence it's widespread use, in this respect, you too are correct.

Also, the higher purity of the gold, the grater it's resistance to oxidation

I hope this is helpful.

Expertise

Have a question about jewelry repair or working with precious metal jewelry and gemstones? For many years up to December 31, 2010, I was a working professional bench jeweler, involved everyday with setting stones in mountings, designing and making jewelry, repairing and limited custom manufacture. If you work with jewelry as a hobby or as a profession, I might be able to help. I deal with the retail business, not mass production. Ask privately if you wish. See the box for that: It keeps your question between us. Please DO NOT ask MAKER'S MARKS, but metal quality marks are fine to ask. Please DO NOT ask diamond prices. See a gemologist for that.

Experience

I have extensive experience in design, service and making of jewelry. I deal mostly with precious metals and gemstones but work with many materials as needed and usable to create an artistic design. My experience also includes freelance photography and photographer of jewelry and similar items for a former employer and individuals. Design of custom items requires reading the desires of the client and being clear on what can be done within that framework...then fulfilling the transition of idea to reality. Effective communications is essential in a working designer/producer and customer relationship.

Education/Credentials
Education is English/Physics! Started in human resources, to advertising, to jewelry...wow, what a road. I have had formal training in jewelry work and many shared experiences with top grade jewelers. We just never know were we will go or be. Follow your best, your dreams, with some discretion! Don't let the work tear up your body along the way as it has mine.
