I'm so pleased it's not the SE made out of copper with a more aggressive base plate because that would be another razor I would have to buy, there is something about copper and brass that I find very appealing .
It'd start dulling to a darker brown, the green verdigris comes much later as the corrosion intensifies. It's the reason the Statue of Liberty is now green, it'd originally have been bright copper, then dark brown, eventually going green as we know it today.
As stated very clearly above, copper and brass are highly reactive metals and will patina (change in color/appearance).
I have a Charcoal Goods copper razor in antique finish (forced patina). I (actually friend) applied a clear coat and I applied
Renaissance Wax (and will re-apply quarterly). In theory, should be very little color change and no change in the blade gap. I did the same on my Charcoal Goods brass razor.
Copper weights more than stainless and brass which could be an asset is some razor designs. I am guessing there are methods to clean copper (brass or chrome or ? polish). In US currency, the "1 cent penny" is made from copper - I have seen many brown pennies, however, never seen a green penny.
Go to the bank and get a roll of pennies in a paper roll. Take it to your backyard and get it wet for about 5 - 7 days straight, not soaking, just damp. It will have some green ones in a few days. I used a Gillette short comb that is stripped of it's gold this morning and it already has water spots on it. They go away when I polish it though. This razor must have a coating on it.
I believe it's not pure copper that would cause problems but it is made from high grade, highly polished Tellurium Copper.
Just got to throw in the science bit to get the punters going, but who cares as long as it does the job...and it does.
Tellurium is often used to improve the machinability of copper and stainless steel. It’s used to make blasting caps, added to cast iron and used in ceramics. Adding tellurium to lead improves the strength and hardness of the metal and decreases corrosion. Many thermoelectric devices are made with bismuth telluride. Lead telluride is used in far-infrared detectors.
I just save with it !!!!!
