The chizlakite: a proteus among rocks
The chizlakite is a slightly less resistant rock than tonalite. It is a magmatic rock composed of light and dark green particles, typically intersected by white, shimmering veins. Because the rock is indiginous only to Cezlak, it is also humorously referred to as a proteus among stones.
Where does the name chizlakite come from?
In 1939 Professor Vasilij V. Nikitin named the rock after the town Cazlak, which got its name after a farmer called Cezlak. In 1891, with the permission of the Windischgrätz family, who spent most of their time in Oplotnica Mansion and Trebnik Manor, Cezlak cleared the slope and started with breaking stone. Ever since then, the quarry has been operating to this day and is one of the best preserved handicrafts, however they no longer acquire chizlakite, only tonalite.
