acid test pass plat. 18kt????
- Thread starter sayvor

If you have an metal that does not fizz or bubble when exposed to Platinum/18k testing acid you got something good. However some nickle tungsten mixes can be very acid resistant. It would have to be made very recent from my understanding to be composed of this combination.
And, as always it could be plated, you will have to go off of heft or do a specific gravity test.
How about a picture?

being I am a jeweler, my only debate is that it is pretty hard to file, compared to other white metals. I know there is a lot of cheap metals now going into dental work these days, cobalt and chromium, (my wife is a dentist, I get her scrap too) I will report back with the official x-ray findings in a day or two. I know it looks good. The story so you know, (I know caveat emptor too) ...on Craigslist this person and older gent, had for the longest time (3-4 months no one bit) this tray of goods his deceased father had found over the years md'ing.... some items were thrown in from yard sale too. I knew nothing really was in it for $40.00 but I took a chance, there were some old coins pennies and V nickels as well as buffalo nickels. the 1909 penny caught my eye as did that ring. A nice little old USA pocket knife yellowish bakelite and 2 steel blades (from the 50's I 'd say) any way.... I dropped the tray while looking at it and I said, I broke it I bought it..... The end. I have done well lately that worst case I lbreak even, which is not bad due to some great finds.... 2-3 of old boy scout scarf holders and weblows etc..there was a fat .925 marked gents bracelet but it was clad. that threw me a little bit. I smell the metals and can tell mostly if it does not have an odor it's probably real. When it smells like metal, it's junk
There certainly is acid resistance metals, some worthless. Last year a friend presented me with a metal rock looking item found on a beach decades ago. Specific gravity test matched platinum, electronic metal tester showed platinum also, as did the acid test. Thinking platinum and nearly 3/4 of a pound and a nice value, I met a metallurgist which offered to test with scientific equipment that shows each mineral in the makeup. Well, low and behold, what the test showed was chromium by product with some other low percentage metals. So, never never use one test ad conclusive. However, if in the form of jewelry, the acid test and surely the electronic tester ate accurate. Hope this helps.
