Heat Anodizing/Coloring Stainless Steel or Titanium

Please do not burn your house down. Propane and butane will work on thinner metals just fine. Something more dense like this knob required something hotter.

It is a common misconception to use the term "anodizing" for creating heat colors. "Anodizing, " by definition, requires electricity. What happens in this video is "oxidizing." ;)

Kids, when playing with fire, move flammable material away from your work area. Especially your compressed bottles of highly flammable gas 🤓

Get a decent sized box of fine copper shavings, heat that thoroughly to the temp required, then bury the part you want blued in it. Also connect the part to something that spins at the speed you want, will make your life so much easier if you want to manually torch the thing.

Just had to comment again, I'm glad you change the title of this one.
A suggestion though would be as I stated previously if you do not seal that color in using an apoxie the color will begin to rub off on your hands and fade.

Looks good. I wanted to see more purple show through. The purple was obvious to see earlier in the heat process. As he worked his way down with the heat the top of the shift knob was still getting hotter since heat rises. Gradually heating the entire shift knob would allow you to decide the outcome of color...more purple means less heat more blue would require more heat. 👌

I was swapping out bezel inserts on a watch I'm modding and got to thinking about how cool the bezel would look heat blued. Going to give it a go after I get my spring cleaning and painting out of the way. Thanks for the vid.

This is oxidizing... to anodize you would use a corrosive solution and electricity to "eat" (cause corrosion) into the material to the desired color and then to seal "lock" the molecules in place (hot/cold/both depending on the material). The largest difference in these two is that oxidizing (what you did) will "rub" away far more easily then the later.
One other suggestion (other then labeling this video correctly) is that when you are doing a video time-laps why not show a timer of actual time spent?

Great job I know this is an old video but you did good. You should be a pro at blueing metal by now.

[challengefarm]

Nice video thanks bro. But dang boy you were next to a ticking bomb with all that fire material right next to the knob lol.

The condensation at the start is because the chemical products of propane combustion are CO2 & H2O. The flame itself is cooling on the steel before it heats up above 100 centigrade and depositing liquid water on the part.

Looks so cool, such a cool concept. Would be a awesome DIY burnt exhaust tips

I wonder what shift knob manufacturer use to massive produce those coloring


especially the neo purplish + blue color looks very vibrant

[iTzxNooBs]

Keep up the work. I know it may seem like its slow but your content gets better and better! I wanna have a garage like you in 10 years! haha

Cool surrounding area with the gas cylinders and the aerosol can👍... This guy is so concentrated in the heat coloring of the knob that his mind is completely out of the safety zone 😄

Around 4:30 I thought you’re trying to torch blue the propane capsule with your mapp torch!

[Ayrtoneverrr]

You can touch it with bare hands as soon you switch off the torch. It will have a light brown to flat dark earth finish 🤣
Great video 👍

[GmonTM]

I want to do this with my stainless steel fidget spinner. Would look so cool!

[umtum]

Is it possible to flatten titanium if you heat it up like this? Like if I wanted to make the top of your item you’re heating to make it flat, is that possible?

[mattia]

Nice video, do you know if i can do this on my stainless steel motorcycle exhuast? Will the color remain?

[Sikeslikescars]

4:23 come on man…. Just begging for that bottle to explode 😂 glad you didn’t kill yourself in the making of this. Stay safe!
