Good morning Taco! I've been selling jewelry for a few years now and have the same metal testing kit as you but without the box. It was $18 and I keep mine in a sandwich baggie. The acid won't eat through the plastic, I've had them in there for a couple of years or more in the same bag and I put the stone in there wet alot. Some use different stones to test for silver and gold but it's not necessary. When you're using the silver test acid you can see the dark brown better if you use a qtip or something white to wipe it up with. Lastly, please please please don't scratch the face of jewelry or other things to test it. Try to use the very edge of the piece or the back of it where it's hidden because it leaves scuff marks on the design and can ruin the look of the piece. Much love to you from Michigan ❤

FYI - In my experience scrapping and selling precious metal jewelry, I have discovered that certain countries are more suspect at marking an item as gold or sterling silver and it not being so. I have come across the most fakes from China and Italy. Just be aware when buying online. Just because it is marked gold or sterling does not make it so. That is why before I sell a piece of jewelry I always test it for confirmation!

Great video Taco. I have that exact same kit here in England and it has proved invaluable - so quick and easy. Thanks for sharing, take care 🙂

Ty for sharing. I learned something. I didn't know the gold 18k acid turned metallic blue on silver.

A surprise Sunday video. Excellent information, thank you! Please don't shovel Tuesdays snow storm.

Good morning to you Taco. I just want to say thank you so very much for sharing this video with us. I do know that I will definitely be purchasing this jewelry testing kit. Have a great day Taco ❤.

Thanks for the Sunday video but this is your day off. Thanks for explaining the acid test kit for jewelry.

Great demo, thank you. Really appreciated the using 18k to test silver, that makes me more confident to try

I watched other KZfaqrs test jewelry they find and I've never gotten a good look at the results. Your marks were really clear and the results really stood out, so thank you!

Oh my, it's Sunday, and we get a video. Enjoy Super Bowl Day. Go KC!!

Happy Super Day Sunday ! Thank You for Sharing 😄 Have a great day !

You can use a magnet but beware of the spring clasps on a necklace because the little spring inside that is not gold. And a magnet will stick to the clasp even though the rest of the chain may be gold. Just so no one tries to trick you.

Excellent advice 😊thanks

This was a very good video for home testing jewelry

Thank you Taco, I have just gotten a testing kit, and this was useful for confirming how I should be using it. I watch your storage videos, so yours came up first in the search. Greetings from Australia!

Thanks so much for the info. Sorry, did you say where to get the test kits? Not on line, but at a store. Thanks!

Thanks Taco, I found this video very helpful. Always nice to get an extra video.

Thank you for this video🤗 I have seen this testing process before, but nobody really showed and told what to look for. I am glad you showed us this. Looks pretty easy if ya know what the heck you are looking at

Great tutorial. Thank you for sharing this information

Hi. Taco. Yay a Sunday video I don't have jewelry but that is so cool.Good to know for storage hunters. Nice Sunday surprize. Thanks.

Taco, thank you for this adventure. I had never seen anything like this before, it was interesting.😮😮😮

Thanks for the demo! I’ve been wanting one of these kits for awhile!

Thanks! This was so helpful! I'm new to this and have now tested earrings I found at a garage sale that are marked 18K. The line didn't go away, so I'm very happy that my $1 purchase should now be worth considerably more. Especially appreciated your tip about testing silver with the 18k solution. I have a ton of that type jewelry to test so that will be a big help!

Thank you, great info. Take care.

Taco when the line turns brown under 14k it is 10k

Good info Taco…thanks.

I've seen people do this type of testing before and have always wondered does scratching it on the stone damage the jewelry?

That's a really great explanation of how to test the metals easily. Thanks !

Nice surprise to see taco on Sunday 😊

Very informative Taco, thanks

Thanks for the video it was very interesting 💍

How would I know that a pawn shop is giving me the right price on gold ?just curious and thinking of selling some gold jewelry

Thanks for the video! You can use the platinum acid to clean your stone also.

Thanks, Taco! Your video was very helpful to me!

Oh cool these are fun tests!

Great demonstration! I have to say as a jewelry lover that hearing that scratching caused me pain lol

Good video Taco stacks 😊

Great information, didn't know any of this thanks 😊

That was very interesting Taco! I know nothing about metals, so I would be hard pressed to know what was what!! Thank you for sharing this information with us!!! Blessings always! ❤️✝️😊

That was really interesting...thanks for the video

Hi Taco! Thanks for the chemistry lesson. Have a blessed day and smoochies to Salsa!!! 💖✝

I bought one of those kits a few years ago (Cheap and works well) Thank you for showing the 18k on silver, It will make it a lot easier to confirm silver. Could never tell the difference between the red and the brown.

Taco stacks! Taco stacks! Taco stacks! Thanks for taking the time to share this with us all ! I appreciate you! Stay safe stay great and keep up the good work!!!!

Thanks for the lesson Taco! 😉

Thanks for the Video Taco Man!

Thanks for the tutorial.

Great video. Thanks!

Thank you for the information

Very interesting, thanks. ❤🐨

Thank you ❤❤

Your good Taco Stacks thank you have a great day…

Taco's first ring acted like 12k gold-filled, not straight gold. The 14k went lighter and red. It might be 14k, but I'd have a professional check before selling as gold. Old sellers toss the silver solution; once you've seen the 18k make silver "curdle" up there's no mistaking it. I sold jewelry for 18 years and almost never needed the 22k or platinum acids. (I've found counterfeit 14k early and often - Chinese brass. Anything marked Tiffany is automatically fake until proven otherwise. Etc,) . I use ivory soap and water to get the marks off of my stone. Works fine. If an item scratches up a different color - silver or gold scratches red etc - no need for acid. It ain't.

Thanks Taco searching for my kit now

No need to apologise mate thanks for showing us take care and please give Salsa big hugs for me 👍🇦🇺

You can also use a magnet

Interesting, thanks.

Interesting. How do you clean the stone?

Taco the teacher,👏👏👏👍🏻🤠🇬🇧

You should put the acid on the line going in the same direction and there would be less waste and easier to see

Very informative...I usually take to jewery store, and get cash in hand...😅 most of the time you can also use a magnet...won't srick to gold...🥰🥰

What does it mean if the marks for 14k gold fade and turn redish?

I have a lot of jewelry from family members and just received a testing kit. So glad you did the presentation. If I find gold and silver, where do I go to sell it?

How do you know if it’s gold filled though???

So you’re picking the 49ers?

How about a white stone? wouldn't it show color better?

Rub it with a q tip. If the q tip is red, it's silver. Easily to see that way

😮 acid scares me!

What type acid for 10k and 14 and 18 22 and 24 are they all test with different type of acid plz get back to me and write like chlorine for 10k murtic acid 14k etc plz and thanks

Would any materials give a false positive? I tested a ring today that came up 18k, but it just really doesn't look like gold to me.

how many seconds should I wait

What if my 18k gold bracelet fades, but doesn’t fade entirely? I can still see a slight outline of the scratch

👍😊👍🌟

925 use 14kt
