This reply is for Catwhisker only. If you are not Catwhisker, do not try this at home as it involves dangerous acids, and may be misconstrued to encourage precious metal recovery, which is not a topic endorsed, encouraged or endured by the Boardsort forum. This post is an identification aid only. If you are a resident of California, please put your laptop or phone or whatever device you are using to view this post in protective state approved hazardous material packaging and take it to the nearest state approved disposal center. You may also wish to wrap aluminum foil around your head to protect your toxic knowledge from contamination of other peoples brain, or else to protect your secret knowledge. I don't know which or how many Propositions # this post may violate. Note: if your name is Catwhisker, continue reading. you can cut or break the blade to see if it is obviously copper/brass/bronze composition or other (after magnet test of course to eliminate spring steel. Then, you can cut scratch or abrade the gold color finish to determine its apparent thickjness, ie, flash or plate. Next, drop the sample in a small container of diluted HCl (after reading a dozen pages on how to mix a dilute solution my adding drops of acid to water...NEVER WATER TO ACID. If the solution with the sample is not knocked off the shelf by the cat, or knocked over and spilled, in a few days, the blade will dissolve from underneath the gold flashing or plating, leaving obvious gold "foil" which is illusory, as it turns to gold smear if picked up. If you find out anything, let me know. Back in the days when I wanted to get rich and believed old scrappers tales about how they made millions clipping pinhead sized contacts off blades, when a silver dollar was still worth 75 cents in silver, I wanted to be a scrapper instead of a skinny hungry kid. Back then, I looked terrible in fat mans clothes. I still look terrible, but at least the fat mans clothes now fit. With a clip clip here and a clip clip there, I soon realized I was getting nowhere, so I got a job and ate occasionally with a little pepper and ketchup. Rumor being spread by acquaintance who buys and sells in volume is that the overwhelmed refinerys are currently not taking plated and other material. What better way to end a pointless discourse than with throwing out another unknown factor? I acquired a load of equipment that had relays with a couple dozen spring wire blades, in several rows, pairs and stacks. On the end, each had a tiny gold rectangle on top and bottom of the spring blade, so it could contact with the one above and below. The spring wire itself was a muted hazelnut brown. I took some to the local yard with a "Gun" xfr/rfx/or whatever it is called. They said the contacts were 31 percent gold, blah blah percent gold. Anything that good is too good to scrap, so I guess I'll just keep them where they are until someone throws them in the trash while I'm not looking.................................
