- The Istebna sandstones are one of the main stone materials used for centuries in the construction industry in Kraków and the surrounding area. It was supported not only by their decorative properties and technical parameters, but also the proximity of the outcrops. The results of research on changes in the physical and mechanical properties of samples taken from the Czasław and Sobolów deposits are presented. They represent two structural varieties, subjected to fatigue by cyclic processes of freezing and thermal shock. Such a treatment of the samples was aimed at recreating the natural conditions in which the stone elements are subjected to the destructive effects of atmospheric phenomena associated with temperature changes during winter and summer periods. Data on the weather conditions in Kraków for the period 1951-2020 were used to assess the effect of climate on the intensity of the impact of the two above factors and, additionally, the destructive effect of rock salt, used for de-icing road surfaces. An attempt was also made to forecast the expected rate of destruction of the Istebna sandstones, based on the analysis of climate change.
