翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Firescale ： ウィキペディア英語版 Firescale Firescale, also known as firestain, is a layer of oxides that forms on the surface of metal when heated, as by a blacksmith heating a tool. On mixtures of silver and copper, such as sterling silver, it is a red or purple stain. At high temperatures, oxygen mixes with the copper to form cuprous oxide and then cupric oxide. Attempts to reduce this problem usually involve replacing oxygen with another gas such as hydrogen or ammonia. It may also appear on gold mixtures with a very high copper content. Firescale commonly develops during the soldering process in jewellery manufacture, for example soldering a bale onto a finished pendant. The stain can only be removed by further polishing, or removal of affected metal; or it can be plated over. ==External links== *http://www.silversmithing.com/1fire.htm 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Firescale」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
