Some Aspects Concerning The Chemical Analysis Of Raw Materials Used In Glass And Ceramic Industries (In Polish)

The difficulties of sample preparation and checking of natural raw materials have been presented. As examples the problems connected with the analysis of kaolin and sand have been described. The sampling of specimens, the proper method of sample dissolution depending on the mineralogical form of impurities, sensitivity and precision of determinations have been discussed.In case of determinations in many laboratories and method of samples preparation precision and sensitivity of the method of determination have to be the same.
