Contactless dilatometry was used for the thermal analysis of a set of glass cullet samples collected in the surroundings (including the forest, gardens, etc.) of the Janštejn glass factory. The collected set of samples covered the time period of approximately one century. The glass composition was measured by X-ray fluorescence spectroscopy. A method of verifying the correctness of the contactless dilatometry results based on the Priven 2000 evaluation of thermal properties was proposed and verified.
