Heat Coloring
(Oxidizing) Steel
Article © MAIL User: The Mad Mailler
What You Will Need
- The Steel or Stainless Steel you wish to color (obviously…)
- A heat source.
-These include Ovens, Acetylene/Oxyacetylene/Propane torches, Kilns, or even Fireplace Embers. - A device to hold the rings.
-This can include a simple wire to string the links on, a firebrick, a pan for ovens, or anything else.. However, these three would be best. - A bucket of water
- An open air space
- Maybe gloves. Not needed though.
Setting Up
Ok, now go outside. Sweep away flammable stuff. Now there’s a few different ways to do this, depending on what tools you have/decided to use.
With a Torch Hung on a Wire.
This is rather simple, pretty much idiot-proof!
1. String the links on the wire.
2. Light up the torch. Now, put the rings in the the flame, and shake the rings every once and awhile to get an even oxide coating.
3. When you like the color, stop and quench in water.
With Your Burning Fireplace Embers.
Get a fire going, until there are embers under the fireplace grate.
1. Thread as many rings on the wire you can fit, make sure it covers less area than the amount of embers in the fireplace.
2. Throw the thing in there…
3. Slow Roast until you like the color.
4. Dunk in water to cool.
With An Oven or Kiln.
This is also easy to do. Set the temperature, Bake, then cool. Just like making a pie.
1. Put the links on a pan or some holding device or your creation.
2. Here comes the *slightly* more complicated part. You need to set the temperature to get the color you want. Note that a conventional oven may not get the higher-temperature colors. Since the metal is a conductor, the heat may be conducted out of the steel than is is conducted into the steel. Here is a chart for the colors:
- Pale Yellow----300°F
- Bright Yellow—350°F
- Straw Yellow---400°F
- Dark Straw Yellow--425°F
- Bronze------------450°F
- Purple------------475°F
- Violet------------500°F
- Dark Blue-------525°F
- Light Blue------550°F
- ”Clear” (Very Light) Blue---575°F
Here is a picture of the colors you will get. I tried to get the spectrum as drawn out as I could, but I couldn't make the purple show much. I ground and shined a broken file on a grinding wheel, so it isn't as shiny as it can be, and the picture also isn't as pretty as it is in real life.

And That’s About It
Have fun with your colorful rings!
