Section snippets Properties of starting kaolin. Kaolin used in this work was collected from deposit Vrbica, Arandjelovac basin, Serbia. The kaolin (~ 150 kg) was dried at 105 °C until constant mass, milled 10 min in a ball mill, (capacity of 50 kg) and homogenized. Chemical composition was determined using Xray fluorescence spectroscopy on an Oxford ED 2000 instrument.
