Gold Filled or Gold Plated How To Tell The Difference

[@johnhamilton6591]

Between watching Dan and learning the mining and panning technique for raw material and yours for the testing and processing of commercial material, the educational levels are 20/20. Thank you so much. Keep them coming and keep up the good work.

[@PHUCKyoutube689]

Dan is good. Check out Jeff Williams if you haven't. He is a geologists and prospector. Lots of good info on how to find gold bearing ground, gold extraction, mining and mining history. Plus he is quite the character.

[@romangarcia1252]

I liked this video. Thanks. Another option is to use concentrated nitric acid instead of diluted royal water, directly on the piece. It is the easiest way to know if the piece contains solid gold, gold filled or gold plated because the acid attacks the metal faster.

[@teresafortnerballentine825]

Thanks so much for this video! I wish that I had seen this earlier today, I got suckered into buying a piece that was supposed to be 10k & it turned out to be plated! I’m kicking my own a$$ because I know better. I did the acid test & it tested 10k. Then later (after the purchase) I got home & used the magnet test & the entire thing stuck to the magnet instantly! Uggghh! You’re video taught me a lot, thanks again! 🙌🏻

[@sreetips]

File deep into the metal. Apply a drop of 10k or 14k test acid to the file mark. I use 14k acid. Observe. If it bubbles, turns green and stinks, then it’s plated (or filled). If nothing happens then it’s probably 10k. I’ve seen 10k stick to a magnet.

[@johnnyblueeyes8037]

Most plated jewelry will be marked . For instance it will say 18k hge or 14k ge. Hge is heavy gold electroplate and ge is gold electroplate

[@sreetips]

Yes, some will be marked and I should have mentioned that in the video - rats. But in my experience it's rare to see gold plated marked. It's usually not marked at all. I find the HGE on the inside of gold plated rings.

[@megazab13]

Thanks Sreetips for another good video. I was about to ask you about some older watches I have that do not have any markings. Wasn't sure if they were gold filled or plated. I'll test them with the acid and stone method like you did. I have found that some pocket watches have a heavy gold plating and was wondering if they are heavy plated, could they be used in my gold filled pile I am accumulating to refine the gold from later on? One more question if I may. The liquid droppers you use in your other videos, are they glass or plastic? ( was thinking plastic and acid don't do well together) I've found these Kookeli 3ml dropper pipettes on ebay and was wondering if they were the same as yours. Thanks so much.

[@sreetips]

Pocket watch cases that are gold filled will say "20 year warranty" or something similar to that. This means that they are guaranteed to not wear through the thick coating of gold, as you slide it in and out of your pocket, for at least 20 years. I have a pocket watch listed in my eBay store that is marked like this. So yes, they can go into your gold filled pile. The disposable droppers that I use are plastic. I only use them once or twice then throw them away.

[@sreetips]

Yes, get some 14k test acid eBay. Take the piece and add a tiny drop right on it and see what happens. If it just sits there with no reaction then it could be gold filled (a thick coating of karat gold over brass) or solid karat gold. If it bubbles, stinks and turns green almost immediately then it’s probably gold plated, just a few microns thick (almost nothing).

Interesting. Although you have ruint the object and its good for just reclamation. Is there a non destructive method of testing? Like for when people are buying the jewelry.

After sorting through thousands of pieces over the years, I’ve learned to tell just by looking. But some pieces are very deceiving. The only way to be sure is to test it with acid. The acid doesn’t lie.

File deep into the metal. Add a drop of 10k gold test acid. If nothing happens it may be karat gold. If it starts bubbling, turning colors (green) and stinks to high heaven, then it may be gold filled.

There are three kinds of gold scrap that I am familiar with. 1) gold plated, or fake gold, or "costume", that is a very thin layer, just microns thick (a micron is one millionth of one meter) of gold plated onto a base metal. 2) gold filled which is a thick coating of karat gold over a base metal and is several thousand time thicker than gold plated. 3) karat gold that is an alloy of solid gold containing about 50% pure gold by weight depending on its karat.

[@chrismoore1555]

Hi I was just wondering how much gold filled scrap you come across that is not marked .

[@sreetips]

A little here and there. Most of the big pieces will be marked. To test, put some 14k test acid on the piece. If it's gold filled then the acid will just sit there with no reaction. With gold plated, the acid will almost immediately eat thru the very thin gold plate on a plated piece and there will be bubbling, fumes, and the acid will turn green.

[@JJ-up5ie]

A sterling video like this? What exactly is tarnish resistant sterling wire please? Thank you!

[@sreetips]

According to the book, "Silver Economics, Metallurgy, and Use" by Allison Butts, page 5, English Sterling silver was formulated about AD 1200 and consists of 925 parts silver and 75 parts copper. On page 9 the author claims that, "Until the 16th century the air was pure and did not affect silver. But the use of coal, and later mineral oil and coal gas, for lighting and heating put sulfurous gases into the air and tarnishing of silver resulted". So I don't think that there is such a thing as tarnish resistant Sterling silver. If some other metal is alloyed with it then it's not Sterling.

[@buggsy5]

I don't know if it is legal, but I have seen sterling that has been rhodium plated - but still marked as sterling. Since rhodium is a platinum group metal and rare, it would not decrease the metal value of the sterling. White gold is also sometimes rhodium plated.

[@mikesmithey1892]

What would happen if you dropped a gold-plated ring in the solution in a solid gold ring in the same solution?

The acid would quickly begin dissolving the junk metals under the gold plated and the solid gold would remain unscathed.

So i tested my "solid" 14k gold bracelet , I filled a bit so you can notice the scratch and I poured the 14k solution and it kept smoking for minutes . Is it gold filled? Or why does it keep smoking . It didnt turn green or crazy brown . Everything seems to wash off??

[@wxchv3.0]

I've only scratched tested my jewelry and they all passed but I was skeptical on the bracelet that I got so I filled the scratch and like I said it keeps on smoking. Why is it doing that? Ive spent about $3000 at this "jewelry" shop inside a supermarket. What should I do?

[@wxchv3.0]

After i had scratched it with a file and applied the acid right after i was thinking maybe it was reacting to the metal from the file so I washed it and i scratched super hard the test pad rock not sure what its called sorry lol and i applied the acid and it did nothing at all , i then dropped a drop of acid on the bracelet again where I had just scratched it on the pad and nothing happend. After washing it good with soap . I dont see much marks that I can notice. Maybe im not sure but it might be a tiny tad bit darker kind of like more copper color. More like it lost its super shiny look.

Its marked bbb on one side and 14k on the other side

[@wxchv3.0]

I bought a chain there almost a year ago and its fine . The shop has been there for years and offers payments . I bought everything cash . Not sure if he can lying about what hes selling . Ive even asked him if hes sure its all solid 14k and he says yes its not filled or plated.

[@sreetips]

Nothing worse than feeling like you've made a bad purchase or that you got ripped off. After reading all your comments, it sounds like you've got solid 14k there. The acid don't lie. If you scratched through deep into the metal and applied 14k acid, and the scratch on the stone stayed there, then it's probably safe to conclude that you gold is real. If it was gold filled then the acid applied directly to the gold would immediately begin to react with the base metal forming green goo and smelly fumes. Take a piece that you know for certain is 14k and then take the $3k piece and scratch them both right next to each other on the "touch stone" then apply the acid. Let it sit and watch what happens. If your still not convinced, take it back to the seller and ask him to test it for you and let you watch. You're probably ok, it's good to be vigilant because thieves abound!

What about "10 KB" gold rings?

[@sreetips]

I’ve seen 10kp. The p means plumb, plumb means it has the correct amount of gold by weight. They include the p because a plain 10k mark can only contain enough gold to be 9.5k and still be stamped 10k.

[@elchichi]

@@sreetips Thanks ST! Wow I really am loving your meticulous work and content. So, it's really hard to read the band but on closer inspection, it's a definite clear and evenly deep "10K" stamp with what is perhaps an engravers error which looks more like a second K or maybe a T. The maker's mark is KB.

[@sreetips]

Test it with acid. The acid never lies.

[@JFerFer]

Hi! What if the gold lifts & kinda floats?

[@sreetips]

It does that due to gases given off as the base metals get dissolved by the nitric acid.

[@JFerFer]

@@sreetips thank you for replying! So, that means the item is filled or plated? More likely filled, since it doesn’t disappear?🤔 …it’s fun learning this…but it can get tricky!

[@sreetips]

The thick coating of gold remains intact. The brass under the thick gold coating dissolves in the hot dilute nitric. This gives off lots of gas bubbles. The gas bubbles cause the gold coating to float to the surface. Until all the brass gets dissolved. But even then, trapped gas in the gold foil could cause it to remain buoyant after all the brass is gone.

[@sreetips]

Right now you can use fake paper money to buy real metal. Dollars used to be backed by gold. Most people think that they still are. Ask your bank teller, "true or false, are dollars backed by gold?" Eight out of ten of them will say, "of course!" And most have never heard of the term "fiat currency." This ignorance is what allows the Fed to continue to print money as they need it to promote a false economy. Why would anyone store their wealth in a medium that can be printed out of thin air? But they can't print more gold and silver. Using fiat money has been tried over and over throughout history and it always fails. Every time. But maybe, in this era of modern technology, it will be different this time. Not!
