通过测量阴极还原所需的毫库仑数来估算在加热的铜上产生的氧化膜的厚度。薄膜厚度与加热时间的关系表明，抛物线定律y2=kt+A仅在短时间内有效，对于磨损表面，A不为零。有色铜上的彩色薄膜可能含有铜和氧化亚铜--显然是在亲密的混合物中--但在强氧化条件下，一层单独的煤烟薄膜(可能是氧化亚铜)会模糊后面的颜色。
The thicknesses of oxide films produced on heated copper have been estimated by measuring the number of millicoulombs needed for their cathodic reduction. The relations between film thickness and time of heating indicate that the parabolic law y2= kt+ A is only valid for short periods and that A is not zero for abraded sur-faces. The color film on tinted copper may con-tain cupric as well as cuprous oxide—apparently in intimate admixture—but under strongly oxidizing conditions, a separate sooty film (presum-ably cupricoxide) obscures the later colors.
