peer agreement (net): +1etched Explanation: Se for uma corrosão por ácido, etched é uma boa opção. (ClauWolf, você pode falar O que é atacado? Com o quê?) etched Etch (v.t.) 1. To produce, as figures or designs, on mental, glass, or the like, by means of lines or strokes eaten in or corroded by means of some strong acid. Note: The plate is first covered with varnish, or some other ground capable of resisting the acid, and this is then scored or scratched with a needle, or similar instrument, so as to form the drawing; the plate is then covered with acid, which corrodes the metal in the lines thus laid bare. 2. To subject to etching; to draw upon and bite with acid, as a plate of metal. I was etching a plate at the beginning of 1875. --Hamerton. 3. To sketch; to delineate. [R.] |
