Oxidation: Metal Turning Another Color

A group of oxidized metal objects. A copper water basin, its surface having oxidized from bright orange-gold to deep brown, with greenish patina appearing in the recesses, while raised areas and frequently handled spots retain a brighter color; an iron candlestick, its surface covered in a deep gray, almost black, oxidized layer, not rust; a pewter teaspoon, its color a soft matte gray. These color changes are unevenly distributed, varying according to the object's shape, manner of use, and exposure to air. None of them have been polished back to their original state. They are placed on a dark wooden board, with a rough earthen wall in the background. Light comes from the side. Avoid: polishing metal to its bright original color, using artificially aged uniform coatings, making the oxidation distribution even, including chrome and stainless steel.

一組表面氧化的金屬器物。一只銅製的水盂,表面已經從明亮的橘金氧化成深褐,凹處出現青綠色的銅綠,凸起與常被手握的地方仍保留較亮的顏色;一個鐵製的燭台,表面是深灰近黑的氧化層,不是鏽;一把錫製的茶匙,顏色是柔和的霧灰。這些顏色的變化都是不均勻的,依照物件的形狀、使用的方式與接觸空氣的程度而分佈。沒有任何一件被拋光回原本的樣子。它們放在深色的木板上,背景是粗糙的土壁。光從側面來。避免:把金屬拋光成明亮的原色、使用人工做舊的均勻塗裝、讓氧化的分佈均勻、加入鍍鉻與不鏽鋼。
