If an Olympic gold metal is really just silver with a gold coat, is a silver metal just bronze with a silver coat? Then what's in the core of a bronze metal? Cream cheese? Mashed potatoes?
It's reverse from what most people think. You bite it to confirm it ISN'T soft. People used to dilute the gold with lead, making it way weaker. You bite to test that there's no lead in it.
That's what old cartoons have taught me. I don't remember what shows/movies, but I definitely remember characters biting down on gold to test it and being delighted when it came out intact and rigid.
I remember learning to treat lead like going to the toilet, ie always wash hands, they didn’t say it but I’m pretty sure that means to not bite it either 😂
Cody, I enjoy your videos very much. The way you present your findings and information in a logical and easy to understand manner make these extra enjoyable to watch. I just wanted to say I appreciate all of your videos and the time you take to make them. Thanks!
i love how zero of his titles are click bait he is all about being true i love it cody keep up the work of being the awesome science machine of a man you are:)
It's so nice to see your channel growing so quickly! I remember watching you when you had like 5 videos uploaded thinking "man if he keeps at it he's going to get huge". I wasn't even that into science before I started watching your videos. It's nice watching videos where you actually learn something.
Cody, it's fascinating and very interesting and simply wonderful how you not only perform experiments but that you do them so well and thoroughly. Thanks!
the best 9999 gold bar testing utube i have ever seen, way better than other videos which they are wasting my time to talk craps and not actually testing the gold. this vid taught me a lot of things. You got the point, the real PURE gold won't oxidized but gold plated gold will. thumbs up! btw i have the same map gas from home depot!
I was always a silver and gold buyer, especially 100oz silver bars, but platinum is ridiculously low in price compared to gold. I'd be buying the rarer 1oz platinum bars instead or silver bars. Never buy precious metal coins(unless you get an amazing deal), always buy bullion which is much closer to the spot price. I expect a pullback in metals(short term), then load up. :-) Just the fact that the gold bars being sold on Ebay are only 8-30 dollars, that should tell people something. Bars that are stamped can be fairly hard from the compression, but cast bars that have been quenched, also are fairly hard. Nice gift the gold crowns. $200 gold value.
The process of heating and then cooling metal to return it to a more malleable state is called annealing. Just in case anyone was wondering. It's something I learned on my degree when we did fine metalwork.
Well. You could technically lay much more(or less) force behind the center punch depending on your weight/strength. Because you still push on it after it has "fired" (bottomed out). I.e. Aluminium is quite soft. And I have made various "depths" depending on how I do the "punch maneuver". Makes sense?
I get the feeling Cody likes gold not because of its mouth-watering value but strictly because of how interesting its physical properties are. Kudos to you, man.
Tin is the main reason that you bite the coins. If tin is alloyed by poor smelting practices it "cries" when bitten. You would hit it against a marble slab on old registers to her the correct sound.
i dont think so, iron is specifically used in the haemoglobin part of you red blood cells, which allows oxygen atoms to attach to them. I dont think gold can replace these iron atoms, but if you could, that would be a great form of savings! lol
no...? But if you eat lead or mercury it will.... If your iron is replaced with ANYTHING other than more iron, your body is fucked. Gold is actually one of the only metals that your body doesn't reject or react badly with if ingested in pure form. It's also great for some implants for this reason
it's so funny seeing cody show the hardness of metals by biting them instead of refering to some professional hardness tests or doing one himself :'D (also I'm a learned Metalworker, which makes alot of your stuff VERY interesting to me, so keep that up!)
I've heard it said that biting into gold comes from times when Pb was used as a counterfeit. Meaning you bit into it, and if it was dented considerably, it meant that Pb was the core of the bar.
2 reasons I know of as to why pioneers bit into gold coins. One you covered, as it was a simple way to test if it was a plated piece of base metal. The second reason was to mark their coins so that if they were stolen and recovered, you could say, "Well I know it's mine because you should see 2 little bite marks on it" in a certain place. A poor man's version of engraving their mark.
The same alloy will have different properties depending on if its certified and if its cheap. The cheap metal doesn't have the crystal size and direction controlled and the crystal size isn't consistent. The cheap metal will have different amounts of cold work from one end to the other, pieces of slag, stress, etc.
for highest softness there is a procedure goldsmiths use. its a 2 step method. 1 heat treatment is to red hot and and air cooled. 2nd heat treatment is to black hot and quenched in water. this will make gold the softest it can get.
+Go IntoTheCalm, harder materials (or at least materials that make a harder alloy). Other than tungsten through platinum, plutonium, and neptunium, gold is the densest metal.
You only briefly mentioned the metalurgical reason that people used to bite gold. When alloyed, it is harder, much more than most commonly available metals of slightly lesser density. Gold coins would normally be a slight alloy (enough to make them fore durable and a bit less dense)to the point that it would be possible to make a lead core with gold plating, which would be much softer. If a gold coin bent or was otherwise soft, it would have been considered fake.
the whole biting gold thing came from biting gold coins which were alloyed gold and quite hard, if the bite mark was very pronounced it was gold dipped lead or something similar.
Most all gold coins from the 1800's had these bite marks. Cowboys did not want to be stuck with Fool's gold. That was their verification of authenticity.
Not to worry about losing the "collectors value" on that bar. They are not recognized as having anything but the value of the gold content, which is certified. I have some, they are easy to come by. Most gold coins however, may have additional "collectors value" depending on demand especially if they are more rare.
why not, I understand biting is very old primitive method, in school we learned about Brinell test and Czech invention Poldi Hammer which is based on Brinell test, it is simplified and practical method used in Poldi Kladno steel company, this simple tool holds together ball made of very hard material and known reference metal, when you hit it with any hammer, same force acts on both materials and then you simply divide diameter of dents in tested and reference material... same principle as your biting, but you get quantified result, then you can compare the ration with table of previously measured metals and you can also guess what metal or alloy it is, not super accurate, but very practical and fast method for hardness measuring
+Matthew Smith And you should, but best practices and what's practically dangerous are different things. Keep in mind, people who handle lead are likely to be handling a lot of lead over time. So it isn't one time, it's chronic exposure.
It wasn't the biting of the gold, it was the bending of a gold coin while holding it in your teeth. This was it's original purpose, for tradesmen to ensure the coin was genuine when no other means of testing was readily available. Now that you've softened the gold bar to the same softness as an old gold coin, try and hold one end in your teeth and bend the bar. Just slightly, that's all that was needed back then.
IMPORTANT , Make shore that the gold bars in certified case like cody has,has a letter infront of the serial number and has not got damage to the retaining inner captule. Only buy from reputable bullion dealers. I beleive that everyone should consider buying some gold and silver as financial insurance because the world is in financial trouble and in hard times,GOLD ALWAYS WINS. Do your own research please.
I always thought mock-biting Olympic (world championship, Commonwealth games, whatever) medals looked kind of cheesy. Are you testing to see if it's solid gold? It isn't. Never was. So what's the point of doing it? Gold plated silver alloy, most likely. And now I see athletes "biting" silver and bronze medals, which makes no sense at all.
so lead is toxic because the body mistakes it for a neurotransmitter. but a lot of people are saying that its not as toxic as people think. that makes me wonder if it was only such a big deal when dissolved in gasoline because finer particles are more readily absorbed into the brain, but large pieces can only dissolve off the surface resulting in far less lead getting into the body. what do yo guys think?
Sammy, lead compounds can be toxic. Pure lead is not. However, if 230 grains of pure lead is accelerated to 850 fps, it can penetrate the skin and thus it can be quite dangerous.
+Blaine Nay Okay I'm sorry I thought lead on it own was a neurotoxin. Although I imagine there would be some oxides on it, and other lead compounds. It's just a bad idea in general to bite lead, although I'm glad he didn't do anything life threatening
Ingestion in sufficient quantities is toxic, though chelation can treat it rather easily, and considering that he grew up around lead mines and returns there over the summer, I'm sure that he is aware of the symptoms and knows a doctor that is comfortable with treating it.
I've heard that it was more to make sure the gold was not alloyed with lead, giving you much more material per gram of pure gold. But this also means you can make a much deeper impression than the small mark you made with the pure gold.
It was used to check for gold-plated lead coins back when gold coins actually circulated. The teeth would penetrate the plating and expose the lead beneath.
Can you please do a video about investing in precious metals? Like reputable sources,good tests and also explain the market (perhaps links to good sites for the values)
great video Cody, might I recommend a zoom H1 for the audio? you can plug it directly into a Canon with a cheap stereo audio cable, just experiment with manual audio settings on both and it'll sound great. all the best Paul
The tested pure gold bar may not have the same value as a collectable but is still just as valuable as it was before on the gold market as it is still 1 oz pure gold. Hope that makes sense.
You should make a video on the creation of different crystals with various chemicals, perhaps test for piezoelectric elements in each of the crystals of different chemical composition? That would certainly be interesting!
May I add, it's a common misconception that historically, people would bite gold to see if it is genuine. The misconception is that if the gold dents, then it is genuine. But the truth is that old coins were often counterfeit by using lead cores and plating them with gold. The recipient of a coin would bite it to see if it was lead, because a lead coin would malform much easier than gold. So, biting dents does not a gold coin make.
Biting a gold coin originated back in the frontier days when lead coins would be gold coated to imitate weight of a gold coin .Therefore wise men would bite their coin to make sure it was not soft lead .
I take it you realize that Olympic gold medals are silver with a gold coating. The only reason they bite the medals is because the photographers think it looks good.
about it possibly containing tungsten: that's what the good counterfeit gold bars actually are. they have a tungsten core with some gold plating. i believe it also passes the water gravity test, and a number of other common tests as well.

its actually filled with a vacuum! dyson i think ;)
Next Video: Biting Plutonium
Yeah but he is obviously going to chew on non toxic metals
Now thats just inconsistent
I think if Cody could get his hands on some plutonium (he can't) he would probably bite it.
Nah, Pu is to hard.
ProgHead777 // If he would want some pu, he would just build a nuclear reactor!
I mean if private energy companies making nuclear reactors can get it, why can't he?
It's reverse from what most people think. You bite it to confirm it ISN'T soft. People used to dilute the gold with lead, making it way weaker. You bite to test that there's no lead in it.
Yeah I've heard this too. It was on no such thing as a fish a while ago.
Ye it's said that fake gold coins can be bent with your teeth in the pirate ages
Toby Messerli I believe it was on QI too, once... =)
That's what old cartoons have taught me. I don't remember what shows/movies, but I definitely remember characters biting down on gold to test it and being delighted when it came out intact and rigid.
***** Exactly my point...
This Episode of Cody's Lab was brought to you by the American Dental Association.
I thought you were going to bite the gold while it was red hot.
Yeah, it's not like he NEEDED those tongs to hold a hot metal anyways, right..?
same
That would be insanely painful
It would make it much softer though!
me2 i was getting nervous
2:25
ah yes, biting lead, known to be an extremely toxic metal.
truly, safety is a priority here.
I eat paint
Fishermen bite fishing sinkers all the time and they don’t seem to be bothered by it. Lighten up and live.
i wish he would do a face reveal
yeah, that would be cool.
Revealed to be bill nye the science guy
nice
No one would like him then
No, people don't think he is like Bill Nye, but it do. He is the black science man.
I remember learning about the "bite-test-to-determine-metal-hardness" in my graduate material science classes, Lol.

Hi Grant Thompson
hello grant
+Fjdbend Fllf woah bro
I'm shocked at how beautiful the gold bar was even after being heated and cooled. It kept the image very well!
Cody, you're weird, amazing, yet weird. :D
I'm going to start buying gold when my channel get as big as yours. I'm glad you did the bite test with different items, so I don't have to.
I was always a silver and gold buyer, especially 100oz silver bars, but platinum is ridiculously low in price compared to gold. I'd be buying the rarer 1oz platinum bars instead or silver bars.

I bet platinum worked out well for you lol. I'm hopeful to get price discovery on silver within the decade.
This was good advice 5 years ago. 🤦♂
The process of heating and then cooling metal to return it to a more malleable state is called annealing. Just in case anyone was wondering. It's something I learned on my degree when we did fine metalwork.
a simple cheap tool for comparing metal hardness is an automatic center punch, it is pretty much calibrated to impact at a constant level every time
en.m.wikipedia.org/wiki/Automatic_center_punch
Thats a good idea actually.
+Cody'sLab sup cody
+totally not stewie love the vids
Well. You could technically lay much more(or less) force behind the center punch depending on your weight/strength. Because you still push on it after it has "fired" (bottomed out).
I.e. Aluminium is quite soft. And I have made various "depths" depending on how I do the "punch maneuver".
Makes sense?
I can't believe you bit into $1,200
I can't believe you thought that was real, dumbass
I can't believe you thought it was fake, because it a genuine gold bar. If you bite in it, it still holds it's melt value
0:21 right middle, Olympic Obama. :D
Searching "Biting Gold" in google also brings up Cody there with the Olympians. :D
I get the feeling Cody likes gold not because of its mouth-watering value but strictly because of how interesting its physical properties are. Kudos to you, man.
Mouth watering? Ha!

bite into the red hot gold waaaaay softer and a bit spicy XD
Now gold bar is more valuable than ever because of Codys toth mark on it! Great way to increase value of stuf.
I would love to have a tungsten sword

The same alloy will have different properties depending on if its certified and if its cheap. The cheap metal doesn't have the crystal size and direction controlled and the crystal size isn't consistent.

Are you planning to celebrate your 750,000 subscriber by doing a melting a diamond video?
you cannot melt a diamond. it is physically impossible
+YouJustCantBeatMeGuy (Lyrite) false diamond melts at 3550 C. please don't talk out of your ass.
I think it also needs to be done in a vacuum otherwise it changes from solid to gas. Like I said "I think".
You can melt it, but not in high amounts and its very expensive.
+Henry Yeah, it will combine with O2 and form CO2.
for highest softness there is a procedure goldsmiths use. its a 2 step method. 1 heat treatment is to red hot and and air cooled. 2nd heat treatment is to black hot and quenched in water. this will make gold the softest it can get.

Nile Red has done something similar to that on his channel if you would like to check it out.
lol when he heated the gold he said 'okay' and I thought he was about to bite a red-hot gold bar after biting lead. Cody will do anything for science
But can you bite gold with gold?
yes.
+Go IntoTheCalm, harder materials (or at least materials that make a harder alloy). Other than tungsten through platinum, plutonium, and neptunium, gold is the densest metal.

did he just bite lead?!?!
yeah i wouldnt do that and he bit the thoriated tungsten rod i wouldnt bite either of those.
No biggie, he didn't eat it, and casting bullets puts out more lead fumes.
rich5562000 yeah but i have been told if you even handle lead you should wash your hands thouroughly before even touching your mouth/food.
hink about how many fisherman bite led weights....It's not harmful in that small of a dosage.
+Matthew Smith And you should, but best practices and what's practically dangerous are different things.

This is kind of silly but do you have any advice for first time precious metal buyers?
Buy from a reputable company or dealer, not someone in China on eBay.
buy from apmex, silvertowne, provident, atltantis mint, monarch precious metals
Go to an actual coin shop.
+Cody'sLab thats ok but usually over priced
IMPORTANT , Make shore that the gold bars in certified case like cody has,has a letter infront of the serial number and has not got damage to the retaining inner captule.
Only buy from reputable bullion dealers.

Re-read: "...now I see athletes "biting" silver..." I have seen this, and it's completely silly..
Olympic medals were solid gold at some point... 1904, 1908, 1912 - they were smaller and they stopped awarding real gold due to wars.
i'm pretty sure that the only reason they bite gold medals is the press
You may be quite right.
Comment section is quite sad here :/ I love these types of vids, Cody.
You should have bitten the dental crowns.....
They are Made to bite with so I guess oh wouldn't Really do anything
Well I lit my "gold chain" on fire, and I NOW know it's not real gold lol that's disappointing
Olympic medals are gold plated so the bite test is pointless.
I think it's just tradition lol
Its not a tradition, more like a trend.
now days they have 0 gold
+Sor Sor Science07 still solid silver under that coating tho
They were solid gold at some point.

Cody thank you for putting this video's on TH-cam. I learn a lot.
Can you please do a video about investing in precious metals? Like reputable sources,good tests and also explain the market (perhaps links to good sites for the values)
great video Cody, might I recommend a zoom H1 for the audio? you can plug it directly into a Canon with a cheap stereo audio cable, just experiment with manual audio settings on both and it'll sound great.
all the best

The tested pure gold bar may not have the same value as a collectable but is still just as valuable as it was before on the gold market as it is still 1 oz pure gold. Hope that makes sense.
You should make a video on the creation of different crystals with various chemicals, perhaps test for piezoelectric elements in each of the crystals of different chemical composition? That would certainly be interesting!
That was a nice anonymous donation. A quick estimate says those gold teeth are worth about $200 together.
May I add, it's a common misconception that historically, people would bite gold to see if it is genuine. The misconception is that if the gold dents, then it is genuine. But the truth is that old coins were often counterfeit by using lead cores and plating them with gold. The recipient of a coin would bite it to see if it was lead, because a lead coin would malform much easier than gold. So, biting dents does not a gold coin make.
Biting a gold coin originated back in the frontier days when lead coins would be gold coated to imitate weight of a gold coin .Therefore wise men would bite their coin to make sure it was not soft lead .
"You can bite gold and.. you can bite with gold" Bless his heart he was so proud of that. Genuinely funny tho. Loved the vid.
"There we go" Bites molten gold bar 😄
@ 4:30 "...a puddle of molten gold on my hands..." that would surely hurt and leave a scar.
It did last time.
how did you manage that?
I take it you realize that Olympic gold medals are silver with a gold coating.
The only reason they bite the medals is because the photographers think it looks good.
about it possibly containing tungsten: that's what the good counterfeit gold bars actually are. they have a tungsten core with some gold plating. i believe it also passes the water gravity test, and a number of other common tests as well.
Gold is an anti-microbial metal so it prevents the tooth below it from later carieses
