Hi, this is a possible answer to the person who asked if the inside is made of lead or another material. In that case, in addition to the acid test as shown in the video, what you can do is to measure density. First you put the metal item in water and see how much the water rises, that will give you the volume of the item. And then weigh the item. Now divide mass by volume to get the density. Now check this density with the known density of metal from a chart. (This test pre-assumes 100% purity)
@MetroActiveTV The thickness for gold coatings and platings are often expressed in millionths of an inch, microinches, or microns. Most jewelry has 6microns of plating, which means that you can rub off the gold plate with your thumb if you rubbed it long enough. Now, that being said, is it possible to create a much thicker plating designed to fool jewelers and the test?
Now, that being said, is it possible to create a much thicker plating designed to fool jewelers and the test? Yes, but it will substaincially raise the price. Remember that gold plate is gold, so it cost money, a-lot of money to buy the gold plate. If its only purpose was to fool jewelers then it would fail. If the jewelry took a file to it - a common practice- he would quickly discover the lead underneath the gold plate making the piece of jewelry ultra useless and expensive.
What if you are testing silver, and the spot starts out red/brown and then slowly turns blue (like in 3-5 minutes, verses something that turns blue right away?
@bkre8ive If it is plated, that means that there is a very small amount of gold in the item. When you apply the acid on the sample (gold scratched line on stone), there will not be enough gold to pass the 10k test which is looking for at least a gold content of 40%.
@manamimnm The Kit is Pretty Cheap, you can purchase it here on our website under Careers Section (Black area at bottom of any page) Follow the BECOME A GOLD BROKER LINK. We provide these materials for our Brokers.
@manamimnm As for the kit, it is best used for jewelry that you are not sure about and that you would not mind if it gets scuffed. We would not recommend using it on a gold coin as some of the coins value is determined by its condition. Some coin collectors even encase the gold coins so not to get any oils on them. If you are worried about scuffing, you can always apply solution directly on jewelry, and test it that way, however some pieces may have a thick plate and might beat this test.

i have to do a school project and i need the formulas of those acids.
Could you please tell me? :)

5 different acids to test a metal. 2 Acids and one test you should be able to determine gold karat, silver, platinum or palladium.

what if it is coated in gold but inside is lead - a practice that the Chinese have perfected to fool consumers. Won't that foil your test?

how do you know if these metals are not just plated with this type of testing?

Thanks for the video.
How much is the testing kit and from where can I get one?
Will it eat any grams from the bar or coin?
