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.

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.

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.

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.

My consideration before watching the entire video: "I don't understand... gold leaf is many times thinner than a human hair, but if you weight it to be 20g, it surely must be 20g worth of material. If you don't get 20g of gold, that is another story, but that is due to its purity, not thickness..." Conclusion after watching the full video: " Yeah, I agree with you, that was indeed 20g of rubbish material, probably some electroplated metal"

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.

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.

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

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.

As a gold leaf specialist: That is not real gold - mostly alloy of copper, zinc, brass/bronze, and aluminum - depending on the supplier, but still called gold leaf. The real gold leaf is 10-12K white [alloyed with silver], 16K pale, 18K Lemon gold leaf [75% gold with alloys copper for red], 21-22K Moon Gold [alloyed with Palladium], or 22,23,23.75 & 24K [99%+ pure]. 24K gold leaf is purer and so soft - extremely delicate & has to be mostly handled with special brushes as it sticks to fingertips when pure. Nothing pounds as thin/malleable as gold, except maybe palladium or silver, but pure silver leaf is thicker and easier to handle but will tarnish faster once it is touched - can turn dark just like copper when oxidized.

If you wipe the gold leafing with nail polish remover with acetone or solidify it into the acrylic using methacrylate monomer then file it they will turn copper. So yes a fun fact is that Soaking and wiping gold leaf with acetone will expose the copper ❤ I have to be very careful when applying it or I will make the nails look copper and not gold. I have always wondered how they “paint” the copper gold.

That's not pure gold leaf. That's what guilders call composition gold; an alloy that looks golden, but is probably some kind of bronze or brass. Real gold leaf comes in purities of 12 to 24 ct, depending on color, and while it IS incredibly thin (about 100 atoms worth of thickness), the foil IS as pure as that carat indicates. 1 leaf of 80 x 80 mm contains gold in a value of maybe 1 buck. Real gold leaf you cannot hold in your hand; it curls up into nothingness under the influence of your skin oils. And, yes, copper can be drawn out almost as thin as gold. But composition gold is way thicker than gold leaf, no reason to go through the elaborate process of beating that is used to make gold leaf. That's why you can handle composition gold with your hands.

Copper and silver are also available in leaf form. Amazingly I just found out they make platinum and palladium leaf too. The scrunched up pieces like that are called schabin. There's also lead leaf too, I know that from an episode of Mythbusters. "Imitation leaf gives the appearance of solid gold despite the fact that it does not contain any gold at all. It is composed of some combination of copper, zinc, and brass and is much less expensive than gold leaf which is its primary drawing factor."

Dan, one of these days I would love to come and visit you and work for a month chasing that ore vein on the surface of the Blue Chip mine like you said you wanted to do. You could probably extract 50-100 tons of ore from the surface during that time. Most of it would be poor quality because it would be from the surface, but you said you wanted to expose that vein along the surface. Who knows, maybe you could have a 2-4 week long event where folks pay a small fee to come and camp at the mine site and then help clear off the area you want during the day as well as help collect ore for you while they get a few pieces for themselves along with learning the ropes of hardrock mining from the surface. You could invite guest speakers to give talks about the best way to stake claims, do research looking for potential new claims in areas, and exactly how to check for gold in quartz that you can't see gold on the surface of, etc. etc. etc. I would absolutely pay to go to an event like that. Also, I was wondering why you don't follow the logging companies and check along the new roads they cut as they log an area looking for quartz and sulfide deposits?

You can "cold weld" clean metal in space because there is no oxygen to create an oxide crust. When two similar metals come into contact under such conditions, they'll immediately weld. No heat needed. Also, aluminum oxide is that "slag" you have to scoop out of aluminum melts. Once that slag is cooled you can grind it down and glue to to paper to make sandpaper. Aluminum oxide ranks a 9 on the Mohs scale of mineral hardness, just below diamond.

I have one of those. It was given to me by my girlfriends grand daughter. That is the real value of it to me. It's not worth what she paid for it, but I wouldn't take a thousand dollars for it. It was very interesting to find out the actual content. Thank you. As always great video.

Gold is a unique substance as you only need 1/8000 MILLIMETER to produce a coating! So you can melt theoritically 8000 leafs just to produce 1mm which is virtually nothing. It is the main reason its preferred in computer chips as the plating can be so thin yet effective. Bags like this mainly have the gold plating the rest junk thus weighing 20 g.

I have been gilding for over 35 yrs. I save all my scews (scraps) to melt at some point. Composition gold leaf(Dutch) is not gold at all. Its #2 or 2 1/2 in colour and is either 85% copper and 15 % zinc or 88% copper and 12 % zinc. Some leaf companies may add other small amounts of trace metals but thats the normal mixture. So Dutch gold leaf has no gold at all. Also bronzing powder is not gold either. Its brass copper and zinc and other minerals to make other colours. Imagine if gold bronzing powder was real gold, a lb of powder would cost a fortune so its all cheap metals. Aluminum powder and copper are mostly what they say they are. So far I have had one very large gold ring made with my scews and saving for another.

As I e been told by chemists. Gold is the only metal that can be drawer as thin as a hair. Gold leaf as on electronic fingers is plated gold as I understand.

The dead giveaway on that gold foil was the color it turned as soon as the flame touched It and it tarnished like copper or brass. Gold wouldn’t change color, just get brighter until it glows haha

Yeah I was told that that Gold flake was fake and I was just a scam a long time ago. I think the reason somebody took testing acid to it and it dissolved the whole vile. They said they literally had no gold to show for her after the test. I wish I could find that video. 😊👍
