Hi: The whole point of stainless is that it's hard to oxidize, at
least at room temperature. Luckily it will oxidize easily when
heated to a red-orange heat. Just let it cool in air. The
resulting scale is quite tough, though it can rust in the right
conditions. Should not be a problem if the ring is worn
Hi Philip, Steve and I tried several way to develop heat scale on
stainless and found the color to be uneven and the surface rough.
And as tenacious as that scale is unfortunately I don't see it as
tough enough for rings.
