There's a 99% chance I make myself some titanium chopsticks now lol. Thanks for the super interesting video! I've never heard a better explanation of how the oxide layer works!
The vibrance of the color increases exponentially as the surface finish improves. Taking the time to polish to a mirror-finish with a jewelers rouge or very fine grits + metal polish is worth it. I've had good results using a small buffing wheel on a Dremel tool. Most lathes don't spin fast enough to effectively hand-sand a small diameter part.
Cool project, though none of it would fit this channel, would be to make a gearbox to increase the speed, a planetary gearbox would probably be the best design for a lathe. The smaller bearings on the output would be better suited for higher speed, lower torque applications anyways. Basically, adapt the larger lathe to do the work a jeweler's lathe would; which would expand the amount of work you can do with a single lathe, when it would normally take two. Another set of cool projects, though more complex, but would add to the decorative bits of projects, would be adapting a standard lathe to a rose engine, straight line engine, geometric lathe, and other forms of jeweling. Which could work on both the original lathe, and the adaptation that makes it a jeweler's lathe; again, making one tool do the work of many, using removable attachments, which is money and space efficient.
Maybe neutral the headstock and chuck up a straight die grinder. Might have to modify the collet but you will get your 30,000 rpms. Just use flapper drums and a buffing wheel in a drill.
I never found those Dremel polishing wheels useful. They just don't seem to do anything but throw around whatever compound or paste you're polishing with.
If you want to use the heating method, putting it in some brass or other metal shavings can help distribute the heat and get very even colors... (looking at you, Clickspring, with your rendered-looking, perfectly uniformly heat-blued screws)
I've done this with both titanium and niobium. Niobium, in my experience, produces more vivid colors than titanium. The anodizing process is supposed to also work with zirconium, hafnium, tantalum, and vanadium. I'll be giving it a try as soon as I can get proper samples of these metals.
I have a pair of metal chop sticks which come apart into two pieces that you thread together, which makes them much more practical to carry around. So there's your next level challenge, adding thread cutting and tapping into the mix :)
as a PVD surface engineer, I should say that color is not a result of "thin film reflection". the thickness of the fill must match the wavelength or half wavelength which means at least 200 nanometers but the thickness of the film you formed here is only tens of nanometers, not more. it is due to another physical effect that is out of the scope of this content.
Fire Hazard: Be very careful with the Ti shavings, these can be set on fire with a lighter and they BURN very hefty. Do not use water to put out a burning Titanium shavings, it will only make it rage even more.

So grateful for this deep dive into the physics. Tidbits like how bubbles and oil surfaces work, that the reflectivity of the titanium matters, etc were all gems. Thank you!!
Iridescence also depends on the light source. Compact fluorescents and LED lamps have gaps in their spectra, so some of the iridescent colours won't show. It depends on the mix of phosphors in the light. A good rule of thumb is that the cheaper the light the fewer wavelengths emitted. They'll all have at least one red wavelength, one green wavelength and one blue wavelength, and they'll all emit those with a balance such that a white object will look white. But with the cheaper ones a yellow object (for example) may look a lot darker than it looks in daylight because that particular wavelength is not emitted by the lamp. So if you're using iridescent chopsticks, eat _al fresco_ for the best effect.
Try using some nail polish to make patterns on the titanium and use electrolysis. Your pattern will be left unoxidized so make sure to anodize it to a complimentary color. Also working your way from low grit sandpaper to high grit will change how you perceive the colors. The green will become much more vibrant this way. Just some tips from a knife lover. ❤
That's true! lots of things will do this, which I probably should've made more clear. I got some really nice colors from copper when I was working on my magnetron years ago. Got some rainbow rings where the plasma concentrates.
@@thethoughtemporium Copper has an even more interesting phenomenon, in that it will form certain colors in the reducing atmosphere of the flame of a torch, which will then immediately vanish or change when oxygen gets to it. It would be interesting to see an explanation of that. Is it a thin film of some form of unstable copper carbonate that immediately burns off to carbon dioxide, or is it some other interesting chemical reaction? I want to know!

That was a super cool video! I did not expect to be learning about why bubbles and oil do the same thing and how all of these scenarios are connected through the way light works. Damn that was a good watch
I work at a company that makes high end optical assemblies, we have are own thin films department and are own machine shop. This video is right up my alley which is always rare!
These are beautiful. I swear I always thought the titanium colours were just some sort of paint. Fantastic to find out the reality. I remember first seeing rainbow titanium as earrings in a shop when I was a kid and was fascinated ever since.
Tophat 1024 I would think the stickyness would be a good thing, since it would have to stick to the grooves of a diffraction grating to get the optical effects. The only problem I can think of is the expansion gallium experiences when it solidifies

Beware carbide is brittle and has a 3 to 5 thousands radius on the cutting edge. This typically means you need to take at least a 5 thousands cut. Anything below is doing really funky work hardening.

Anodizer here. Hydrofluoric acid will also remove a blemished ano, an etch it so it’s ready to ano again. It gives it a matte look, sanding gives it a nice shiny look
great video! one small correction: at 10:20ish you say "one color adds together to be constructive and all the rest are destructive" it's actually the other way around. soap bubbles and oxide layers are always a mixture of gold, cyan, magenta, and the shades between them from the destructive interference of one specific wavelength of light. if it was constructive interference with one wavelength that made the biggest difference, it would go through various colors of the rainbow, but it goes through all combinations of colors aside from one wavelength. the phenomenon is called pearlescence if anybody wants to look it up. you can imagine this the same way that they do that cool colored shadow demonstration at science shows and museums, where they have three colored spotlights pointed at the same spot so you have cyan, yellow, and magenta shadows from your body blocking out one of the red/green/blue spotlights, and the other two lights combining on the canvas. (blue and green for cyan, red and blue for magenta, red and green for yellow)
Hi, just wanna say thanks for the videos. I am currently studying photography and your videos really explore in detail lesser known science which for me always gives me amazing ideas for incorporating your science into my art.
After being a subscriber for a while everybody knows it's not just a simple video And that's why I keep watching your channel. Good work keep them coming 👍
I used to put patterns on metal I would heat it up a little and start a color shift, then I would mask with tape and cut out patterns and sand the part with the tape mask on. Then remove the tape and heat a little longer. Stuff that has not been sanded will continue to shift color while the sanded area will start new color shifts. This give you the ability to make any custom pattern possible!
Great video. You must have missed This old Tony's taper power feed mod - he has a tee-piece made out of steel rod that he uses to snag the handles on his crosslide, then drives it with a reversible cordless drill. Takes all the ache out of repeated winding, and allows pretty smooth and steady feed.
10:05 given that blue appears at thicker oxide layers, it could be that what's happening isn't that blue is getting a boost by constructive interference, but rather that a color close to orange is getting destructively interfered, meaning that you see its complementary color: blue. I'm not sure though, I'm basing this on the fact that for a color to get interfered, the thickness of the film has to be some multiple of the wavelength (or half the wavelength I think) of that color.
@1:58. Make an insert for your tool post that is a skate bearing on a stick and slowly feed it into your stock until you cant indicate and/or see wobble. Then tighten. Works great for centering things in a chuck too because it only applies pressure to the side that is out of center the most.
Well I’m into science and I just started watching your channel,You should have much more subscribers and this is very entertaining because of lockdown so yeah I might just binge watch you.
I have done this with my steel chopstick. Works exactly the same way. I thought you would talk more about the valence electrons variability in Titanium/ d block elements.
This is very interesting. I work at a factory where we make shocks for cars. And in the center is a steel rod which we harden and temper in high heat. After tempering a lot of our steel rods look exactly like your titanium ones.

May i ask if Its possible to make an difractiom metal? Can you cast gallium on a difraction grating and then get the rainbow effects on an metal?
Probably not with gallium as it has a very high surface tension and is extremly sticky when molten.
Tophat 1024 I would think the stickyness would be a good thing, since it would have to stick to the grooves of a diffraction grating to get the optical effects. The only problem I can think of is the expansion gallium experiences when it solidifies

one small correction: at 10:20ish you say "one color adds together to be constructive and all the rest are destructive"
it's actually the other way around. soap bubbles and oxide layers are always a mixture of gold, cyan, magenta, and the shades between them from the destructive interference of one specific wavelength of light.
if it was constructive interference with one wavelength that made the biggest difference, it would go through various colors of the rainbow, but it goes through all combinations of colors aside from one wavelength.
the phenomenon is called pearlescence if anybody wants to look it up.

Then remove the tape and heat a little longer. Stuff that has not been sanded will continue to shift color while the sanded area will start new color shifts. This give you the ability to make any custom pattern possible!

This is really cool, and that was a great explanation of how the color changes
Great video. You must have missed This old Tony's taper power feed mod - he has a tee-piece made out of steel rod that he uses to snag the handles on his crosslide, then drives it with a reversible cordless drill. Takes all the ache out of repeated winding, and allows pretty smooth and steady feed.
Didn't even notice the title, legit thought this was JUST about chopsticks. My mind is blown... Most underrated science channel on UA-cam.
10:05 given that blue appears at thicker oxide layers, it could be that what's happening isn't that blue is getting a boost by constructive interference, but rather that a color close to orange is getting destructively interfered, meaning that you see its complementary color: blue. I'm not sure though, I'm basing this on the fact that for a color to get interfered, the thickness of the film has to be some multiple of the wavelength (or half the wavelength I think) of that color.
First video of yours I've seen. Great content. Thank you!
Popped over from Alec Steele's channel, after seeing your comment. Instant sub. Keep on being awesome and learning new things!
@1:58. Make an insert for your tool post that is a skate bearing on a stick and slowly feed it into your stock until you cant indicate and/or see wobble. Then tighten. Works great for centering things in a chuck too because it only applies pressure to the side that is out of center the most.
Wonderful video! Beautiful chopsticks! I learned a lot :)
YAY, Love you videos, I like the long ones, but this shorter one was a nice intro for newer viewers! I have sent to many friends!
Well I’m into science and I just started watching your channel,You should have much more subscribers and this is very entertaining because of lockdown so yeah I might just binge watch you.
Thankyou for delving into that information-pit... wonderful vid.
Now I can tell the knife community the science behind the anodized colors they desire 👍👍. Thanks
Fantastic video! Very impressed with this channel. Actually learning new things
Unexpectedly thoughtful and educational. Thanks.
I have done this with my steel chopstick. Works exactly the same way. I thought you would talk more about the valence electrons variability in Titanium/ d block elements.
This is very interesting. I work at a factory where we make shocks for cars. And in the center is a steel rod which we harden and temper in high heat. After tempering a lot of our steel rods look exactly like your titanium ones.
This video goes to 11... You're scholar, an educator and a gentleman! ;-) Thanks!
