何かの参考になればと思い、銅を加熱した時の酸化膜の色の変化を実験しました。
オレンジ→紫→銀→金→赤の順に変化していきます、面白いですね。
オレンジから銀までは200℃で30分ほど加熱した時がやりやすいです。
金から赤の変化は250℃で30分ほど加熱した時がわかりやすいです。
今回使ったオーブンでは250℃が最高でしたが、赤色に変化した後は緑っぽくなっています、300℃でも試してみたいですね。

Not sure if I’ll get a response. When I did this the copper changed back to original color. How do I keep it from changing back?

@PluckyPicky769 Год назад

Will the color still there if you polish it?

@WhenDoesTheVideoActuallyStart 2 года назад

The colour is a result of the growth of the surface oxide layer. If you abrade the surface it will affect the colour.

@BackYardScience2000 3 года назад

Hmmm, it almost looks like they've been switched with anodized pieces. It appears that you can see clamp marks from anodization too. Very skeptical.... 🧐

Do some research. It’s a common thing to color copper using only heat. I do it regularly with a butane torch, the colors this way get even more bright.

@dogodogo5891 2 года назад

doubt he was lying it called resonance some said it was form of transmutation sound crazy right? if u got skeptic why not try for urself u only need bunch of copper and put the on oven

@WhenDoesTheVideoActuallyStart 2 года назад

Anodization is a very similar process to this. Both involve increasing the surface oxide layer. Look up "titanium flame anodization" for more examples.

@@lighttblue . I’m curious , I’ve given electroplating copper onto steel and it keep going pink. One batch, few I got that nice copper brown look. I buffed it and the plate got warm with the Grinder… would heat have a similar effect whilst using a solution (even just brushing it on whilst the surface is still warm/hot ?!?

@Monkeywrench864 Год назад

Are you still working with copper??

@tengucraft Год назад

yes of course!

@Monkeywrench864 Год назад

@@tengucraft I found your video quite interesting. Very well thought out. Probably one of the best as far as testing goes. I too, work with copper. As an artist, I want to achieve the Red color, the problem arises when I want to preserve the color. As no amount of lacquer will do this. It turns Orange.
