为了确定总矿物质含量，例如在完整皮革分析的框架内，可以通过计算或单独确定无机物质。其原理包括皮革碳化，然后用硫酸处理，并在开放式坩埚中灰化。该方法适用于所有类型的皮革。

To determine the total mineral content, for example within the framework of a complete leather analysis, the inorganic substances can be ascertained by calculation or determined separately. The principle consists of the carbonization of the leather followed by treatment with sulphuric acid and ashing in an open crucible. The method is applicable to all types of leather.
