My local thrift stores all have piles of old silverplate-no one wants it anymore, and no one wants to polish it,either. I'm always on the hunt for Sterling, and I've found that Sterling items are ALWAYS marked "Sterling" -especially things made in the US. If you are serious about finding Sterling "in the wild", you have to know foreign hallmarks also-they won't say "Sterling" on them, but maybe just a stamped ".925" or something similar. British hallmarks are more involved, but you are always looking for the lion with the raised paw. At every thrift store, I always go through all the silverplate and old silverware-I've found an amazing amount of overlooked Sterling. My most common find are "weighted Sterling" candleholders-I've found dozens of them in the past two years. They are all just a thin skin of silver around a heavy cement or plaster base, but it all adds up.

The little symbol A is a good guide as to the quality of the silver plate. There are tons of different systems and no standard but a century or so ago, many British makers used followed the gradings ... A1 = Superior, A = Standard and then lower and lower grades below that B, C, D, E based on how many pennyweight was plated on. A1 was usually a troy ounce of silver per 12 tablespoons or forks. Also don't get confused with
stamped in Old English font which looks like a hallmark. That's electroplated nickel silver and usually pretty thin. -
There is a much cheaper way of doing silver plate. The formula is 19 parts sulfuric acid to one part nitric acid. Heat but only to about 140 F. The silver plate will turn white as it dissolves in the solution. When the white is gone, that piece is done. I use three buckets and a plastic colander. I let one batch drain while the next batch is working in the solution. After a batch is drained, I rinse in bucket number one, still in the colander, then bucket number two, then dumped in an empty bucket. Buckets one and two have two gallons of tap water in them. When the solution is spent, it will be very dark and will not take any more silver. I let the solution cool down to ambient temperature. I pour half the solution in each of the water buckets and add a saturated solution of un-iodized saltwater to turn the silver into silver chloride. Work it into silver metal as you wish. You might want to try it in one of your great videos. You do a great job. I enjoy them very much.

Your videos have gotten much better over the last several years........ This one is new to me, but important for me to learn how much effort I should put into plated vs. sterling pieces.... Thanks

You are the Superman of recovering precious metal videos. Always worth watching and thanks Superman.

Mr Sreetips there is a very easy way to de-plate silver. A tub of salt water with a piece of stainless steel for the negative contact and hook the positive contact to the piece of plated silver. Run a current through it for 10-15 min and the silver will flake off

Glad to see you back on!!!

If you undershoot a little bit with the HCl, so you leave just a little silver nitrate in solution. You can filter out your silver chloride, and save the filtrate. You can then use the filtrate to dissolve more silver items, because when you add the HCl you also create nitric acid. You just want to undershoot with the HCl, because if some is left over it will react with the silver and form a AgCl coating keeping the nitric from dissolving it. That way you can save some money on buying more nitric. I actually just did this, it worked out pretty well.

Thank you for taking the time and using your chemicals and shop to show us how to do what you do & now we know to just turn it into a recycling center as the base metal under the silver. ❤❤

Glad you're back, thanks for the vid!

Love your videos my husband done his first gold recovery from scrap fingers. Thanks for the videos please keep them coming!!!

I really enjoyed the calculation of the worth at the end there. Would love it if you did that in every video where you yield some precious metal.
-
Yay you're back! I was worried about your wrists at times with that platinum.

Just as plating I would never have imagined you could get that much silver off of that lid. Understand I dont doubt you a bit as I have learned how sharp you really are at this stuff. Im also extremely jealous at how productive you are and could only hope that I could ever do anything like what you do. I dont like toxic chemicals or agents. I would never work in a trade or plant that would put me anywhere near dangerous lab work. I worked in a production machineshop for just under 28yrs but I would bolt when they had painters painting the floor with very toxic paint. Whenever they painted in that building I bolted to get away. One of the painters never wore a mask I couldnt believe it. You would get a headache right away if you were anywhere near it. Im not exagerating. But you I have learned know exactly what you are doing. Do you have a chemistry degree because you work like a Scientist, I do really enjoy watching what you do and most of all when you end up with an incredible bar of Gold and Silver too. I always wonder if you really should be wearing a good mask or ventilator but I think you know what your doing.

some companies call it Ultraplate, some call it Extraplate. I only found about it awhile back because my grandma had a bunch of it, than I started looking into it. It is very common, mostly older pieces but some newer ones can be found. Yes you can find several pieces with with very thin plating but thick plating isn't rare

I started buying junk silver from my area. I cant wait to try to do some refining.
-
No commercials, I subscribed. love your videos!
-
Thank you for sharing your calculation and satisfy my curiosity about the costs!
-
Great to see you back again! I was hoping that the stock pot refining disaster did not take the wind out of your sails for continuing your videos.
-
I'd say it is a profitable venture seeing where the bidding is, at current time. Quite Profitable if I do say so myself. Great video. Once again you don't disappoint.
