  Hydrofluoric acid will disolve quartz. It probably won't when put into wink as the potency is diluted, but you still should reduce the time you leave it in it. I have worked with hydrofluoric acid and I came about an inch from getting it on my arm. At that close call, I swore I would never use it again. I was disolving quartz and arsenopyrite (arsenic) off  of a specimen. The stuff I used was a mix of hydrofluoric and nitric acid. Hydrofluoric acid will disolve glass as well as quartz. I have a chapter on this in my book, The Nugget Shooter's Field Guide. Muratic acid won't change the texture of the quartz specimen but will strip all coloration out of it. Manganese, iron etc... It will turn rose quartz snow white.

 I roll them into the back of my truck and take them to the local car wash.

But this forums past threads probably have better advise than me. I do highly recommend the white vinegar and salt for smooth worn placer nuggets

Whink will dissolve quartz as well as high potency HF, but it takes months instead of minutes. I’ve stuck my finger in the stuff... they sell it in grocery stores. It works on stuff other acids won’t touch, but will frost the quartz or feldspar if left more than 12 overnight so you do need to watch it.

      PART ONE:
      Pictured below are four gold specimens that I have found and I will discuss what methods I use to remove the host rock revealing mother nature's treasure. I gave each specimen a "letter" designation so you can follow the progress from start to finish on each specimen. Part Two I will discuss the chemicals and equipment I use to clean gold or mineral specimens.

      By using $1800 for gold and $28 for silver as a base a common dime would have a value of 2.02 and a .6 grain (not gram) nugget would have a value of 2.02 if it was at 90% purity.If you want to know the silver amount of a common dime  multiply .07234 times the   spot price of silver.A  .6 grain nugget is tiny.  I  would rather find a nugget then a  silver dime any day unless it is a very rare silver coin.I  imagine you nugget hunters  stumble on to a nice coin  now  and then.I heard Tom Massie found a $20 gold piece when he was nugget hunting.I hope I did my math right.Even with  copper surging to  $4.06 today a  common dime only   has .27 cents  of copper in it.

      What is, if we should, get the dark crust from an old liberty dime to determine date and other details. No scrubbing with steel wool? Acids? Thank you in advance here at this forum for any help you can give.

      So I was killing time eye shopping gold nuggets, I like looking but never buy any until now when I saw what I thought was a really beautiful 29.32g gold nugget pendant. This one was full of character and had a variety of color and texture, the simple silver wire mount cleverly wrapped to hold it securely without solder or permanent attachment the perfect gift for my wife’s birthday. Well, it came in the mail today and for reasons beyond comprehension he decided to clean it. The silver mount I guess melted in the acid, it looks I think much less interesting and the weight is down to 26.2g from it’s natural state at 29.32  a little of that lost fine gold. I’m sure I could return it the seller is very reputable but still like it just not nearly as much, what do you think am I wrong thinking it was much prettier before it was cleaned...should the seller have even done this after posting the pictures in his add?

      I have 3 batches like this. I just listed one on CL for 175.00. Almost all iron items with some brass, ceramic etc. Priced too low? Too high? Going to be getting rid of all my old finds soon. Any ideas, opinions are good to hear. Thanks.
