Put the bar in a hydraulic press and see if it bends. If it does, it’s gold.
Right, LOL. I’ll bet half the guys in the gold business there are wearing those Nolex watches and Ommy Hilfiger crap I used to see them peddling on the streets of NYC in the 1990s.
Pure tungsten is very hard — but, tool steel can cut it. OTOH, tungsten carbide is much harder than tool steel.
Chinese... Tungsten is not easy to work with. I believe south africa has dealt with this and the bars are coming out of china.
Or use a micro-ohmmeter which will clearly distinguish between tungsten and gold. They go for about $3,000 and I think every dealer on 47th street is gonna be getting one.
What weighs more a kilogram of gold or a kilogram of cotton candy?
Actually, in the earth’s atmosphere, the gold weighs more because of the buoyancy of the cotton candy.
A Maltese Falcon?
Yes, indeed. Thanks.
—yep—considering that the concept is three thousand years or so old, you’d think some of these financial geniuses would know about it-—
Au = 19320 kg/M*3
W = 19600 kg/M*3
Since W is more dense, this whole thing gets tough.
Go for the ultrasound solution.
Eureka!
“The ring would be suppressed by the gold coating......”
That would depend on how thick the plating was, I’d imagine.
I don’t have gold, but I do have identically shaped lead, iron, tungsten, aluminum, and bismuth bars and they all have a different sound.
In the olden days a gold coin was bit to see if it was real or gold plated lead. Maybe they should drive a nail through the bars before they buy.
Here’s to plain speaking and clear understanding.
If you kill me, how are you gonna get the bird? And if I know you can’t afford to kill me, how are you gonna scare me into giving it to you?
You’re right. I have done a lot of machining and just have a habit of thinking of all tungsten as tungsten carbide.
LoL, I meant would bars of the same size weight the same.
Hey I’m an old coot, gimme a break.
Boy am I glad to have that settled.
