"Im not usually into jewellery" Nile casually making himself grillz a few months ago

Fun fact: in the semi-conductor industry, this alloy is known as “purple plague” because it’s extremely detrimental to parts. Basically, if gold and aluminum contacts touch at high temp, some purple alloy naturally forms. This alloy is both brittle and a poor conductor, leading to electrical or mechanical failure. It was a big issue for a while, and Al and Au are some of the most common contact materials in chips. So yeah, fun facts for ya. Edit: Wow, this blew up, haha. Glad to start some cool conversations and learning!

As someone who uses sandpaper a lot, I can almost guarantee that the gold that you lost simply just got stuck in the sandpaper. Soft metal is very good at clogging sandpaper grit and with as much sanding as you claimed to have done, I'm genuinely surprised you didn't lose more than you did lol

Imagine being a medieval king and some alchemist walks up to you, pulls out a bunch of bubbling, color changing liquids and transmutes your gold into purple gold jewelry. It would blow your mind.

I love how the chemistry in this video isn’t complicated, it’s just Nile learning that casting metal is complex.

I showed this video to my godfather who owns a large jewelry company and he told me he had tried to make this about 5 years ago and this was some of the finest work he had ever seen

Jewelry companies hate this man, he's showing us the secrets and the methods so we don't gotta pay for overpriced rocks

The fact you just keep going and never gave up, for such a simple yet satisfying outcome, I absolutely love it

One month on, Singaporean here and I just happened to stopped by Lee Hwa for some jewllery shopping. Asked the staff about purple gold and would you know it, the staff informed that this video was shared all over the company internally. Staff shared that Lee Hwa actually experienced a spike in international sales right after this video dropped, so they have Nile to thank for!

The beaker drop had me in shambles until I realized it was just a bamboozle

45:40 yeah this is why jewellers usually use a long thin strip of gold, bend it around a ring sizer, cut it to size and solder together the edges

The solid substance made of more gold than aluminum is truly lavender. If light reflects the thing, it is fuchsia. The jewel looks so beautiful! Even more beautiful without holes!

Nile: "I have no idea where all the gold went!" Also Nile: sanding, grinding, hammering

Whats crazy is you've advanced a field. no one makes cast purple gold jewelry because of the complications. You are now one of the best in the world at that specific task and made it look like a college students term project.

Working in a foundry for many years as a master foundryman we went through a lot of different methods to prevent oxidation on all metals (precious and non precious metals) we ended with using liquid argon on top of the molten metal bath and it worked amazingly. Food for thought!

Gold and Indium Alloy (Au-In): Gold and indium alloys can also produce a purple color. These alloys are formed through coating techniques such as electrodeposition or immersion in liquid indium. Although they are lesser known, they offer a distinctive purple gold-like coloration with better corrosion resistance compared to aluminum alloy

The part with the Aqua Regia is exactly how George de Hevesy hid 2 Nobel Prize medals during WWII. To the soldiers who looked around his lab for valuable things, it just looked like a beaker of orange chemicals. After the war, he precipitated the gold back out and the Nobel Committee recast the medals from that gold.

i am a jeweler and goldsmith apprentice and seeing you drop the beaker "full of gold" game me heart palpitations and i almost started crying in Italian

It is a very beautiful color. More subtle and toned down than natural gold, a color that never struck me, yet this is as nice as white & rose gold. Awesome vid.
