通过直接熔融和搅拌玄武岩、安山岩、科马提岩、橄榄岩、流纹岩和石英闪长岩各50-100 g来制备八种硅酸盐玻璃。这些被称为MPI-DING玻璃，其目的是为地球化学、原位微量分析工作提供参考材料。从各种分析技术的结果表明，个别玻璃碎片是均匀的，相对于主要和微量元素在μ m到mm的规模。在两种科马提质玻璃的小而有限的区域内观察到了由于橄榄石淬冷结晶所引起的不均匀性。为了获得尽可能多的元素的浓度值，在一些实验室用各种批量和微量分析方法对玻璃进行了分析。根据分析数据，计算出60多种元素的初步参考值。大多数元素的分析不确定度估计在1%~ 10%之间。
Eight silicate glasses were prepared by directly fusing and stirring 50-100 g each of basalt, andesite, komatiite, peridotite, rhyolite, and quartz-diorite. These are referred to as MPI-DING glasses and were made for the purpose of providing reference materials for geochemical, in-situ microanalytical work. Results from various analytical techniques indicate that individual glass fragments are well homogenised with respect to major and trace elements at the mu m to mm scale. Heterogeneities due to quench crystallisation of olivine have been observed in small and limited areas of the two komatiitic glasses. In order to obtain concentration values for as many elements as possible, the glasses were analysed by a variety of bulk and microanalytical methods in a number of laboratories. From the analytical data, preliminary reference values for more than sixty elements were calculated. The analytical uncertainties of most elements are estimated to be between 1% and 10%.
