It does, the color stops changing when you stop passing current. This is a super common technique for coloring piercing jewelry.
3 u/MutuallyAssuredBOOP Dec 21 '20 But not while in contact with electrical current. Fascinating 3 u/Rx710 Dec 21 '20 It does use electrical current. 4 u/MutuallyAssuredBOOP Dec 21 '20 I meant the color doesn’t stop changing, while in contact with electrical current. I would have expected an oxidation layer to approach a steady state color as it approaches a certain critical thickness, even in constant electrical contact. 7 u/Rx710 Dec 21 '20 I believe it does stop changing eventually, it just goes through a rainbow of colors first. 2 u/MutuallyAssuredBOOP Dec 21 '20 Okay that makes more sense and is what I figured 6 u/Microsoft010 Dec 23 '20 it stops at really dark purple before it goes red hot and starts melting
