We have many methods we use to test and verify gold bars that come in over the counter.
First see me check the weight. Second see me check them with a magnet. If the magnet has no effect or too strong of an effect, the bars are counterfeit. Next I use the XRF precious metals analyzer made by Niton / Thermo Fischer Scientific. Then I drill the 10 oz bar and test the insides on the XRF. Stay until the end for the quiz and see if you get an A for the day.

Now you have to send the bar to refiner to recast... costs money.

Thanks for making this video

I never knew gold actually reacts to magnets is it because there are other metals?

@philipbaron3 2 года назад

What's the point in having all that equipment if you gonna ruin the bar by drilling it anyway?

@goldrefinery2709 2 года назад

We sell coins. bars, and casting grain. Sometimes we run low on casting grain and we convert our bars to casting grain. Sometimes we just get too much gold and need to sell it off in bulk and we will just make giant bars to sell rather than sell many small bars.

What do you do after drilling it?? Melt and cast the bar into a new one?

@jumzbrugs9867 2 года назад

Lol that's what I thought 😂

@goldrefinery2709 2 года назад

recast into a bigger bar

Usually you can tell if it's not plated or skinned by using your eyes to look at it's purety, if it is identical in coloure content as the outside then it is pure, or just decide when you want to accept that gold is a certain material that is not hard to mistake , and the computer you used audit is disabled in which is the inspection itself.

gravity test gives u right point....not need to drill

cobalt works well

how much is he xrf machine.. where are u buying the smaller bars that u have had no problem with -- do you know anybody that only tests them

@goldrefinery2709 2 года назад

This type of XRF machine sells for about $16,000. Tax was extra as was the test stand, software upgrade, and maintenance plan. We have 2 of these machines in-house. We buy in San Diego, California, USA.

@matttzzz2 Год назад

But the gold bars were moving around under the magnet. Real gold is not magnetic so why were yours moving?

@mrhow2712 Год назад

Because gold is weakly paramagnetic. It tends to push away from a very strong magnet

@KyleHansen509 11 месяцев назад

Certain gold is magnetic yes without other metals it can still be magnetic in it's pure form. It all depends on factors, configuration and situations

They were moving with the magnet. Gold is not magnetic. Please explain.

gold and silver has small reaction to strong magnet

@KyleHansen509 11 месяцев назад

Certain gold in its pure form , gold is. Reactive material and is not really metal before melting, certain factors come into play with understanding "purety of The gold." Such as configuration and situations. It's not a toy.

@robdee3152 11 месяцев назад

so is the drilling really necessary if you have xrf and ultrasound on the 10 oz bar?

@Todor81 11 месяцев назад

I will first calculate volume measuring displaysment when you put a gold bar into the water. Then just calculate weight, with this two values you can calculate purity easily

@balakrushnapanda1799 9 месяцев назад

Pl explain how I do that

@Todor81 9 месяцев назад

@@balakrushnapanda1799 You can use some plastic dish, and fill it with wather to the top of the dish. When you do that you can put gold bar into the wather. Wather that was left the dish is the volume of the gold bar. And you can calculate volume using graduated cylinder. Now when you have volume you need weight of the gold bar. You know what is the density of the Au element. With this 3 values you can calculate the difference of densities

Not very good money if it takes this much work and equipment to verify its not counterfeit. Bitcoin is far superior in scarcity, divisibility, and verification.
