[実験] 加熱による銅の色変化 Experiment color change copper use oven.

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。

理科の授業の参考にさせていただきました！ありがとうございます

ほう砂無しでも綺麗に色が出るんですね。凄い。

[@dickorange3404]

fascinating experiment!

Amazing job! Beautiful

Thank you

[@firesmurf7984]

They stay in colour or when it started to cooling they turns back to your starter colour?

[@PluckyPicky769]

how was the condition on the back? is it has a line mark because putting on the grill tray?

[@forevermorewinds1555]

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?

銅って不思議

[@AnnaKRaga]

The cooper is loyal and wonderful 🧡

[@pw2026]

Will the color still there if you polish it?

[@WhenDoesTheVideoActuallyStart]

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

[@BackYardScience2000]

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.... 🧐

[@lighttblue]

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]

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]

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

[@mJlReplicanT001]

@@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 ?!?

and now how can change all of them back to original color? 🤔

[@mm-ih8ep]

思ってたのとは異なる結果でした。この電子レンジみたいな器具機械はなんと言うのですか？

[@user-ng4sb5nl2o]

Why do the colors differ in some places ? (6:00)

銅だけでこんなに？？

[@adhityaram.916]

Plz any body say what is the original colour of copper.

[@Monkeywrench864]

Are you still working with copper??

[@tengucraft]

yes of course!

[@Monkeywrench864]

@@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.
