翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Q-pit ： ウィキペディア英語版 Q-pit Q-pits are kiln sites which were dug for the production of white coal prior to the Industrial Revolution when white coal was largely superseded by the use of coke. ==Purpose== The white coal produced in Q-pits was largely used in the smelting of lead from about 1550 to 1750, when a process was discovered that used coal. The large sections of white coal had previously been mixed with charcoal to give the right temperature, as charcoal alone was too hot and would have volatilised the lead.〔Rackham, Oliver (2007). ''The New Naturalist Series. Woodlands''. London : Collins. ISBN 978-0-00-720244-7. p. 205.〕 Some evidence exists to suggest that some had a secondary use in the charking of coal into coke.〔〔"to chark" is defined as: to reduce by strong heat, as to produce charcoal or coke.〕 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「Q-pit」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.
