河北省从去年七八月间以来,搞了不少土法炼铜炉子,共有一两千个之多。平谷县在土法炼铜方面首先创造了一种简单的土坯炼铜炉和土式的坩埚炼铜炉。可是这种炉子的冶炼方法缺点很多,现在逐渐被江宁式的土高炉所取代。 Since July and August last year, Hebei Province has engaged in a lot of indigenous copper smelting furnaces, a total of a thousand or two thousand. Pinggu County, in the indigenous copper smelter first created a simple adobe copper earth furnace and crucible copper smelting furnace. However, this furnace smelting method has many disadvantages, and now gradually replaced by Jiangning-style soil blast furnace.
