This characteristic of the damage incurred to sandstone applied in nineteenth-century shrines in Tychy emphasises the particular susceptibility of the non-compact and even crumbling sandstone to changes produced by anthropogenic processes. The conducted examination comprised a foundation for conservation intent on reducing the rate of the damage to the objects and the restoration of their original appearance by means of supplementing the gaps with mineral masses. The studies took into consideration the textural varieties and colour of sandstones as well as their physical and mechanical properties. At the same time, the discussed material is easy to use in normal atmospheric conditions, and does not cause harm to the environment and the health of the conservators.
