This is a post, paragraph by paragraph, to find out which words are banned:
Bob, your question has many facets. For starters, here's the obvious: yes gold jewelry reads in the various TID ranges that aluminum (tabs, slaw, foil, etc...) read in. There's no getting around that, no matter how well you "know your machine". If anyone tries to tell you they can tell the difference between gold and aluminum (by sounds, or programs, or whatever), then quickly take them out to junky blighted urban parks, turn them loose. See how much gold jewelry they get, while leaving aluminum behind
