How much gold is in this 20 gram bag of gold leaf?

- Don't be fooled, not all gold is created equal. Some gold leaf is pure gold, others, not so much. A fan bought a 20 gram bag of gold leaf scraps off ebay for very inexpensive price. He sent it to me to test how much gold was actually in it. The results are shocking but not unexpected.

Just for a fun comparison, the James Webb telescope mirror gold layer is 100 nanometers (600 gold atoms) thick. With a total diameter of 6.5 m (21 ft), the total gold content is only 48 grams.
Just like the capstone of the pyramid is also a gold mirror?
@@oldhollywoodbriar not quite… the Egyptians very unlikely had the ability to cover the capstone with millimeters of gold… that most likely would have been a thicc hunk of gold. Most probably covering something else, not solid through, but there’s always the possibility of that
@@Superintendent_Chalmers I disagree… if you research the technology the pyramid builders had electroplating technology. Even shows it in their glyphs.
@@Superintendent_Chalmers anyone with a hammer can beat gold down to that thickness but I appreciate your attempt to pull off “internet smart guy,” lol. Also, remember, only the capstone, not the whole pyramid. The Egyptians certainly were masters of Gold plating. mold is beaten with an 8-pound (3.6 kg) hammer for three to four hours until it has been beaten into a circle about six inches (15 cm) in diameter. The finished leaf forms an unbroken sheet of gold with a thickness of approximately 100 nanometres ( 1⁄250000 in).
I’d still totally recover the gold if I could get my hands on it lol. That’s with the idea that I was already on a mission that was paid for and I happened to pass by to be able to capture it. I’d estimate close to 100g total in the scope as all of the radiation hardened electronics would have some great components to recover from not just the lense.
I was in a pawn shop and a guy came in with a bunch of that "gold leaf " and wanted to sell it . They did an acid test. The guy doing the test started laughing . He said it was like a magic act. As soon as the acid touched it , it disappeared. Good stuff Dan.
Atleast it dissolved, thats a good sign (usually)
Hi Dan, those foils are actually made off brass. Brass looks very goldish till it is fresh and not oxidized yet. It is used for making cheap "gold" pigments or colours as substitute of real gold. That is why you ended up with pure copper from smelting process. That little bead of gold is most likely left from the previous smeltings on the walls of crucible.
ahh zinc = dodgy smoke?
no that is real gold i have looked it up
I've used gold leaf for years restoring antique picture frames. There is both real 24k gold leaf as well as imitation leaf. They both come in "books" of super thin sheets between papers. Imitation gold leaf is usually aluminum or brass. I suspect you have imitation leaf as I noticed a dark mark on your fingers when handling it. Real gold leaf does not leaf a mark on your skin when rubbed together. Also real 24k gold leaf is pricy. Around $75 for a book of 20 small sheets, which generally contains less than half a gram of gold total.
I use Thai 24k leaf a lot for my resin pours - making Orgonite
Think the ones I got from Thailand are fake, look decent but listing said edible 24k, don't think I would trust eating em
I think its ridiculous that people eat gold leaf. What is the point?
That was a particularly good walkthrough, Dan. Thanks for putting it together.
I love my Sunday morning episodes of prospecting with Dan.
Greetings from Victoria :)
Always nice to see your dad hanging out with you!
Not gonna lie, the smart ass in me, as soon as I saw the title was thinking "Well there might be 20 grams of gold in that 20 gram bag of gold...but I could be wrong"
I literally asked the same just now😂😂
Nice seeing you and your dad having fun.
Thank you, Dan and Doug for your knowledge!
Dude - you two are the most dyslexic alchemists ever turning gold into lead.
Awesome video Dan! Thanks so much. I needed some of your positive energy today. 👍
Love your dad. He reminds me of mine.
Always nice seeing you dad in these videos. Keep up the great content.
Thank you, Dan, for another educational video. I love these experiments you do ❣️
Dan and Jason again. Yes please. Y'all are the best.
Great looking ore you've got there! Would love to see a collab with you and Jason, that guy really knows his stuff when it comes to refining!
Oh forgot to say thanks,v good show and good to see you have your Dad still with you alive, kicking & having some fun together!
Cheers!
"Copper plus 4 - 15 % aluminum gives corrosion-resistant and strong aluminum bronze with a pale gold color. Powdered it's used as a metallic, gold-color pigment in oil-based paints and inks."
Love watching your videos I learn soo much thanks for the knowledge much love from New Zealand
Thanks for all the great info
Gold leaf is a very thin sheet of gold that is commonly used for decoration, gilding, and other applications. The weight of gold leaf is typically measured in troy ounces or grams.
To determine how much gold is in a 20-gram bag of gold leaf, you would need to know the purity of the gold. Gold purity is measured in karats, with 24 karats being the highest purity.
love it, such great positivity from you and your father!
Love the vids mate and where your doing your smelting is a wicked back yard
Great experiment, take care and thank you for the lesson 👍🙏❤️
Hey Dan,
Such a pleasant surprise to see your father in the opening of this video.
Great subject for todays video.
Work Safe, Be Well
Stay Warm
My Sunday fix of Dan Hurd, Hi Doug. Greetings from Comox.
I loved this video. We need way more of this,!!!
Thanks Dan I definitely learned several things from this Video, Your Dad seems to be a fine Gentleman, Please feature Him in more Videos !
What a fun video! I love seeing metal melt/smelt it's so satisfying to watch.
I really enjoy the smelting videos thank you.
very informative love your videos
As a bit of additional info on the topic:
It is not possible to directly electroplate gold onto copper. the gold will just soak into the copper without leaving a visible layer on the surface.
To electroplate gold onto copper there has to be a layer of different metal like nickel in between.
Or on a sheet of paper.
Yes one can its done all the time but there is a way it must be done to make last for a while. I KNOW i was a jeweler for 30 years
@@mayhemdiscordchaosohmy573 interesting. How does that work?
I worked at a circuit board manufacturer in Connecticut all we did was electro plate the boards
2 very smart men!! Thank you for the lesson.
your outdoor set up looks like it should be housing a moonshine operation. ;))
I loved this video. I love when you do these types of videos. Science and experiments got to love it.
I remember that eBay ad exactly! I wanted to put the foils into nitric to verify they were only gold but I had a feeling it was gold plated copper or something similar as you bravely took the financial risk to try for us!
Love the videos with you & your dad.
Great GLoTD and fun experiment to watch. Thank you.
Really like your channel. Doing great keep up the great work
I had heard that gold leaf was a joke but thanks for showing us just how much.
This is going to be another great San Hurd video
LETS START A CAMPAIGN MAKE Dan the man Herd have the highest like ratio we can. I never like videos, but Dan's out here earning not begging, sincerely you are the man. I always love your videos
I see the beard and I hear Burl Ives as frosty
“Silver and Gold
Silver and gold”
Depending on the brand of the gold leaf most of the cheaper ones are mostly copper zinc and brass mix.
Nice job, I always wondered how much gold is really in those souvenirs, thank you
There is an alloy called Nordic Gold that is copper, tin, zinc, and aluminum. It is used in European coins that look gold.
Fun to watch you working with your dad. Learned lots too
Really interesting video. Love your channel
Awesome video idea earned my subscription on the first video ever seen and enjoy every video with the family since Dan seems like a cool guy everyone wants to hang out with and learn something from bet he's a blast to sit around the campfire with and tell stores
hello dan from dan hurd prospecting I've watched every video in the last 1 or 2 years and I still love that intro
There’s something incredible about seeing your “elder male role model” grow over time and evolve and THEN meet HIS father. Mind blowing. I feel like I just met my great grandfather that didn’t know his son had grandkids elsewhere. 🤯
Thanks for sharing dan
Thanks Dan, that was a fun vid
I had around 40 pounds of gold leaf that I saved from being thrown away on the job I was on once. I finally got around to testing it turned out it was mostly copper with a small amount of zinc. The zinc was used I am guessing to coat the paper and then electroplating the copper on it, and it made it look like gold. So as you can imagine, I didn’t spend anymore time on it. I just threw it away. But it was fun watching you. Play with it anyway enjoy your videos very much.
FYI, 40 lbs of copper is worth around $160.
@@savingferris8279 It was mostly paper weight the coating was super thin, so I didn't bother with it. I did however find some old switch gear from a electrical box that was plated with silver that I recovered 2 lbs of silver off of it years ago that was fun.
I know nothing about gold, but, I enjoyed this vid a lot... You got my Subscription, Sir. Pleasure to meet you Dan and Doug 🙂
can't tell you haw many times I've wondered the same thing. How much gold is that really. Loved this one!
Imitation gold leaf, also called composition gold leaf, Dutch metal, or Dutch gold, while made to imitate the appearance of gold, is made from a combination of copper, zinc, and brass.
Backyard geurrilla chemistry with dad! Fun! Yarrrrr...!
Love the try and learn style
happy to see Doug in your video again. was wondering about him
Having gilded quite a few picture frames and sculptures for stage productions, most cheap leafing material is some brass alloy, although real gold leaf is available in various purities (24k for edible like for cakes and stuff).
Edit: most of this cheap stuff is labeled as "gold leaf" despite containing no gold, and comes on pads of tissue paper for application.
Also the cheap stuff needs to be clear coated with polyurethane to prevent oxidation, whereas the real stuff doesn't
hahahah i love watching you and have watched for years!!! we as a family are such a huge fan!!! we had a funny laugh at you being a red head with a little pot of gold and your laughing, such a leprechaun thing. ❤️ happy st patricks day!
Really like the videos with dad Hurd
I'm guessing that this material is mainly brass with perhaps just a flash of gold to prevent corrosion.
That smoke would be the zinc burning off. Once the zinc is gone the melting point went up so the bead solidified.
At first I was wondering how aluminum would work in cupelling; it forms a very stubborn oxide layer with a very high melting point, and I'm not sure the lead oxide would be able to dissolve it. Much of what is currently sold as "gold leaf" is aluminum with some coating to make it look gold.
Your Dad is cool! Good lesson on gold foil, didn't know there is so little gold. Nice
One of the best videos you've done, I cackled most of the time so had to watch it again just to see what I missed.
Glad you enjoyed it
That's AWESOME I always wandered what that gold leaf actually was. Very interesting! I love your channel and always great to see your dad in videos!
A lot of gold leaf is pure gold. It just depends what it's meant for, who's selling it, etc.
very interesting, thanks, Dan
I used XRF in college and when the video started, I was like “Shame he doesn’t have access to an XRF. It’d be a lot faster than this.” Then I got to the end of the video. 😂
Awesome it's good to see your dad it's been awhile
There is an alloy called Prince Rupert's Metal that has no gold in the mix but looks rather like gold, it's 75/25 copper zinc so it's really a brass alloy. It's specifically made to imitate gold.
Thanks for the GLOTD! Wow! Once again I wish I knew what you have forgotten 😂.
thx for the lessons :) untill the next one ✌🤟
So lead dissolves copper does it need to be a specific type of Lead like lead with a zinc coating or does it not matter
this is so amazing i love it guys a very good process 👌👌👍
great as always!
Cupels usually have to be heated to . turn red hot all over, then allow some oxygen flow or air flow over the cuppel......to oxidize the base metals like copper & lead absorption into the cupel. Not easy can take an hour to do this under super hot temps Glowing the cupels to a red color is not easy..I believe the copper mixed in with the gold is making harder to cupel. Great experiment Dan
That is not what my smelting text book says. Nor the manufacturer of kiln.
@@Danhurd Ok, Dan, my mabor cupel is rated up to 2,300 F , you dont have to reach 2,300 F....I melt gold at 1,943 F to 1,950 F depending what other metals are in it like copper 1,990 F , when my cupels turn red glowing is when it works for me, then I allow some air to flow into my kiln and see the absorption take place in the cupel. It takes me 40 to 60 minutes to make it work. Everyone's kiln & torch is usually different, sizes & manufactures. Ok, I seen you cupel in the past, but I dont think you had that amount of copper . The copper makes it harder Dan......ok, I'll edit my comment so theirs no confusion. I also learn from you over the years, so glad your health improved my friend ....Dan 🌝
Peanut butter in the background are the real show stoppers, lol. I didn't realize how much science goes into all this. Thank you for showing us it's very interesting.
GREAT CONTENT, DAN !
(AND YOUR DAD IS A CUTIE)🥰
Congratulations on 1M subscribers Dan.
Fun class today Dan.
Dan,
I was a picture framer for 40 plus years and you to do gold leafing with real gold leaf.
The other leaf was what was called Dutch metal or fake gold.
It worked well on frames and did a pretty good job of imitating the real thing.
That's most likely what you have there, not gold leaf.
When I applied gold leaf to a very smooth surface on a frame, it could be burnished to a really beautiful finish
because it was genuine gold.
A book of genuine gold leaf 22 /23 usually 25 sheets, can run over 40 to 60$ U.S. in todays market
It has a bit of copper or silver to change the color.
fake leaf Dutch metal) can run up to 60$ U.S. Dollars depending on the mix.
Thanks for the great demo,(I mean it, no sarcasm)
Cheers,
Rik Spector
Good job brother! 👍✌

Hello Dan, I enjoy all of your Videos and I want to ask you if Platinum and Palladium Oxidize?
Thankyou Dan !
This gives me an answer to something I've often wondered about before when I've seen those little bottles. Thanks Dan and Dan's dad!
Hey Dan love the videos the blow torch cylinders will get colder when burning causing drop in pressure and heat and if it's winter it will affect pressure too hope this is helpful Dan
Great video Dan funny seeing u in the snow while I sit on my balcony here in Australia 40 degrees or in America 104 degrees 😅
Hay Dan . It doesn't really apply here, but if you ever want to refine Cu from Pb and Sn is present, you can separate the Cu by adding Sulfur at 650f and mixing. If no Sn is present, you can add a mixture of sulfur and iorn pyrite at 900f and mix. You can also use red phosphorus at 750f and dropping .
nice to see dad looking so good
Glad to hear the technical term “Iffy” being used outside of the UK
That XRF machine is amazing! It would be cool if you had the funds to buy one so you could easily tell what ore you're looking at out in the field but I bet it's far too expensive.
Depends on how you define expensive vs almost invaluable as a tool . I've seen a handheld advertised for around $40k .
I love watching you with your Dad. I never knew my father but my grandfather was amazing and started me prospecting and looking for gems the first gem I found was a 3000 pound quartz Boulder I saw just a inch sticking out of the ground and then kept digging and digging and digging and then my grandfather hired a crew and once structure dug out a giant Crain lifted it out of the ground and on the side of the lake one of the straps broke and it cracked it into twenty pieces but they were still large pieces I keep a 300lb piece in my living room it was one of my happiest memories of him. Sadly he was killed the following year. But I love seeing you guys together it's magical please make as. Many videos as possible with him also have him talk about some of. The adventures he had with you as a kid would love to hear his account
Thanks Dan.
6:40 ish... Dan's Dad carelessly exposes that he is part of the wizarding world and that smelting cannot be done by muggles.
Can you burn gold if it gets too hot for too long?
Fun watching you and your dad having a good time together.
