  •   Comment Thanks a lot for your sharp eye, Basile. Personally, I thought the vignetting is just barely acceptable. I may edit the photo tonight, create a derivative, redirect the nomination to it and so try to rescue this nomination. If the nominator agrees, I'll do it that way.

  • Thanks for your message, Basile. You are right, the original is always the very best for perfect optimization. In a JPG you have a lot more work to do to get at least some improvement, as in this case. Best, -- Radomianin (talk) 13:10, 14 July 2023 (UTC)[reply]
  • I've never heard of a copper bleaching process. And he must be mad if he is using bleach with bare hands. I hope someone can explain. Charlesjsharp (talk) 08:51, 15 July 2023 (UTC)[reply]
  • Bleaching is a word that is used about other processes when brightening or removing stains is involved (Wiktionary), not just when you use the chemical commonly known as "bleach". Example: "The sun had bleached the wallpaper, leaving distinct rectangles where the pictures on the wall had been." Some chemical processes when you remove oxidation prior to polishing, are also known as bleaching. This might sound confusing since most people only know about household copper polish, which contains both a "bleaching"/reduction/"de-oxidation" and a polishing agent. If you want to just remove the oxide from copper, vinegar or lemon juice in water will do just fine. The process works much faster if the metal is hot. You can see the water steaming from the copper in the photo. (In Swedish we goldsmiths call the process vitkokning which literary translates to "white-boiling") I guess he might go about polishing the tub with fine sand after he is done with the bleaching, making the copper shiny again (there is a tub with what looks like sand behind him). --Cart (talk) 11:57, 15 July 2023 (UTC)[reply]
