@@moderngoldsmith I seem to remember purple gold is brittle I wonder if you could cast a thin ring shape from the purple and then machine it to tightly fit it to a more formable gold body to protect and trap it a bit like you did here and then engrave/facet it just a bit to draw attention to that deep metallic hue next to a pale metal like brushed white gold.
My wife was a modelist in the lost wax process and she made us a model of wedding band that was poured in green 18k gold. I notice people doing double takes when noticing my "green" wedding band. Your presentation was very informative, I am now one of your follower.
I used to work in a medical parts manufacturer company. I helped build the first fully automated titanium anodizing line in the US. We worked on the recipes for a year and a half. When I left the company, the chemist I worked with gave me samples of the titanium in every color we perfected. That was nearly 20 years ago and I still have the tube with the blanks with me. I loved my work, but I hated the company. It went out of business six months after I left because it was 2009 and they couldn't run a hot dog stand much less a multi million dollar medical implants factory.
@@Tugela60 lol, no. The company was bought by a company that made RV parts and wanted to diversify. Unfortunately medical parts are way more important to keep within spec than a water pump. They kept trying to rush parts through inspection and were sending unacceptable product to our customers, so our customers stopped ordering from us and the shop closed by the end of the year.
The green gold would make lovely vine and leaf accents for rose gold florals. Keep the stronger gold for the structure. It would stand out well in that situation, visual comparison and subtle suggestion.
I had a friend who was an internationally qualified geologist who also designed and made charms and jewellery. He is, unfortunately, long gone. I saw a piece that he made for his lady. It was a small pendant in the shape of a many petalled rosebud the leaves on the stem were green gold whilst the petals were rose gold with stem being of pure gold. To complete the piece he placed a "dew drop" of a small diamond on the edge of the inner edge of the bud. It was a delicate piece valuable in itself but valued especially by the lady involved as it had been designed and made especially for her with love.
I had a Black Hills Gold ring that had a green gold and red gold leaf on it. I had to sell it many years ago to pay off some debts, gone but not forgotten.
Blue gold is an intermetallic similar to purple gold (AuAl2) but is instead either an intermetallic of gold and indium (AuIn2) or gallium (AuGa2). It's a structural color like purple gold so will show when the material is properly heat treated.
the way i have been taught, when alloying with zinc always add it right at the end, give it a quick stir and pour immediately, otherwise the zinc burns off and the alloy balance shifts off
Ahhhh electrum. I made a few simple bands and solder for them out of this a few years ago. It really does look greenish next to rose gold. The alloy is super soft though so I found a hammer finish works best on simple rings.
This brought back memories of my years as a casting jeweler. My favorite color for Electrum (Green gold) is 18K (.751). It’s beautiful. BTW, never use any copper in Electrum. It fades the green. Also, add the zinc last to the mix since it oxidizes quickly.
I was inspired by your knot ring video to make my first soldered piece and of course what better tribute to a Celtic piece than green gold so it happens that’s what I made mine with! So cool to see the process. Thank you for inspiring hobbyists and people just interested in knowing more. Your channel sure is fun and makes the process more accessible. Of course yours is prettier but I sure had fun making mine! Thank you sir.
Unpopular opinion: I think the 16K green gold looks better than the 18K. The 16K looks more green and less yellow to my eyes. That being said, both are beautiful and would make fantastic jewelry 😁 Next purple or blue gold, please 🙏
@@moderngoldsmith Is Cadmium really that bad when alloyed with Gold? Itself it’s relatively inert and gold only makes it more inert. As long as the parts of the ring that touch the skin don’t have Cd, you could use the super-green gold for making small decorations like leaves. Old “Spring Green Gold” recipes look like: 71% Gold 22% Silver 5% Nickel 2% Cadmium
That was an incredibly well done video. More than a video; it was an experience👏🏻 You don't put out videos often, but when you do...very high quality. Thank you 💚
You have to be careful when using zinc in an alloy, because the boiling point of zinc is lower than the melting point of the other metals. The way you did it here, there is a good chance you had a lot of zinc in the air and little to none in the alloy. It is better to melt everything else first, then only add zinc at the end and quickly cool it back down.
My first experience with Green Gold was metal detecting. I found a ring that was marked 10k but looked oddly green and acid tested to higher than that. That's when I learned about Green Gold. Thanks for making this video!
From 1977 through 1985, Royal Canadian Mint Commemorative $100 22 karat gold coins had a composition of 91.67% gold + 8.33% silver. The United States Mint 1976 Bicentennial Gold Metals had a composition of 90% gold + 10% silver. Green gold has the resemblance of a chartreuse hue.
Girl go to the craft store ect and just start making art is relaxing I draw , Kona like a kid , it’s not gonna be hung in a museum but it’s pretty relaxing . Just get sone beats it watever spend donpices iver time if you are short on time
NileRed did this and it was REALLY difficult. Purple gold is super brittle and highly reactive with atmospheric gases, so you need to melt it in an argon atmosphere and bubble the argon through it to remove the hydrogen gas.
So cool! I’d love to see your take on the beige gold that Chanel uses in some of their jewelry. I love the look of gold jewelry but it looks terrible on my skintone so I’ve always stuck to silver/platinum. But I feel like the beige gold would totally suit me.
You could also try making some less common colors like champagne gold, brown gold etc. I remember reading someone mixing in iron in the gold alloy but i don’t know what color
That's very cool, love the subtle variations. A lot of oil painters miss using cadmium yellow - it's a very "true" color. A way to play up the green would be via contrasting it with a complimentary reddish tone like rose gold or a pink gemstone but that is a specific "look."
I'd love to see that green gold inlay in white gold. Or even purple gold. Nile Red made purple gold. It was beautiful. I love the green gold too, very beautiful and unique.
Thanks for your reply. I met you at the Atlanta Jewelry Show when you were with Joel McFadden. We spoke about your rude awakening to the southern accent. 😉
do you get a perfect alloy without stirring or mixing? or is that why you slosh the liquid alloy around before casting? does the atoms auto mix themselves?
That ring looks so good!!! I never knew green gold was a thing, but now that I do, I want some. 😆 Subscribed. Awesome video and amazing ring! Nice job!
You messed up smelting. You’re supposed to bring each mineral to their bowling point separately at the same time then mix them just enough for it to be fully settled. This is so you don’t overhear the metals at much lower boiling points temperatures.
You’re not wrong, but from my understanding “electrum” specifically refers to when gold and silver are found naturally together in the earth, not alloyed together. Hence green gold is a more appropriate title for what I did.
When you were fitting the green gold into the channel of the ring, I totally thought you were making a spinner! Awesome video, I loved the gradient you got with all the ingots lined up.
@@robbiekop7I have indeed witnessed historical documents depicting Lord Percy holding a blob of pure green in the presence of Edmund Blackadder and his manservant Baldrick.

I love green gold!!! 😊 If you mix a tiny bit of metallic cadmium you get extreme greens. Just watched. Good video!!! Worked as a jeweler for a long time. I've seen cadmium green gold that was MUCH greener.
Great video, I was always interested in how the cadmium alloy looks compared to the regular one. You could make that gold alloy color triangle to show all the possible combos. I also wonder if it’s possible to make blue gold that is not too brittle for a ring
My mother got some jewellery made from yellow and green gold in Iran in the 1960s. She was told they use some cobalt in the alloy but I have no idea how much exactly. When we visited Iran in 2015, it was out of fashion but still could be found after some asking around in the gold soukh (market) in Teheran.
Have you heard of blue gold and black gold? Yes it's a thing. Maybe try one of them or both at once 👍 I really like the look of making Rings. I also love gold that I find like in my profile picture 💯👌💚💛❤️
ooh! well hot dang, finally someone giving us visuals for the cadmium recipe. myself I got some cadmium lying around for this reason. lso theres a gold recipe using potassium but considering potassium is stored in oil, it seems scary to light it on fire..
If you beat the 16 karat green gold you can make it much stronger and good for jewelry. 24k gold can be used in jewelry, the key is proper beating of it to toughen it up.
Green and pink gold is why I loved Black Hills pieces in the 90s. I have a few pieces from my teen years, including my high school class ring! I chose the fanciest one in the book, I'm sure! 😂 it is beautiful, though.
Beautiful work! So, what's up with the green gold that Black Hills Gold uses? Is it plated to make it a darker shade of green, I'm guessing. Keep up the great work!
Try making violet gold by alloying with aluminum, or blue gold by alloying with indium. Even crazier make auride salts by alloying with alkali metals ❤
I'm glad you addressed the elephant in the room when it comes to green gold, it really only is green to goldsmiths who spend too much time looking at a very thin range of yellow-white lol. I can't help but wonder if microstructural patterns in a gold alloy could produce a "magic" green, much like our purple gold.
"Cadmium (Cd) additions of up to 4wt% have also been used for the production of 18 carat green alloys. 75Au-23Cu-2Cd results in a light green alloy, and 75Au-15Ag-6Cu-4Cd is the composition of a dark green alloy"
Love this, I always wanted one of those puzzle rings, you know the four interlocking rings, but each ring is a different metal. Yellow Gold, Rose Gold, Silver, and this Green Gold(electrum?) would be great.

Came here for this
When using zinc you should melt the other metals first then add the zinc.
Make a purple gold ring combined with this green color! I am sure the contrast of purple and green will be more vivid and expressive!
Mind blown! Between the contrasting bands and then adding the engraving, absolutely incredible.
Level achieved❤👏

Black Hills gold jewelry has been producing a green gold variant since 1870.
The title reminds me of Blackadder "purest green" episode in which percy makes some "green gold" which isnt gold at all😂.
I had no idea this episode even existed until I was doing research for this video. So happy I found that gem, it's hilarious.

Aluminium and gold, makes purple gold
