- The investigation was carried out on stone slabs sawn and flamed from three commercial types of igneous rocks: the “Sunny Desert” granite, “Twilight” basalt and “Imperial Red” granite. With the following method of laser profilometry, 510 surface profiles were recorded, each of them containing 1280 measuring points. The parameters of roughness and waviness were calculated for each stone surface with a horizontal measurement accuracy of 1 mmandaverticaloneof10mm. The data of laser profiling were correlated with petrographic observations in order to identify the rock components that are most exposed to damage while preparing the stone slabs. The results indicate that the thermally treated slabs have their surface roughness distinctly higher and their waviness higher even several times than the slabs obtained by sawing. Among the three flamed slabs, the highest roughness is revealed by the medium-crystalline “Sunny Desert” granite, while in case of the cut ones - by the unequally crystalline “‘Imperial Red” granite. The waviness of the surfaces obtained by slab cutting and flaming is comparable in both investigated granite types. The “Twilight” basalt, which shows the porphyritic-aphanitic texture and the directional arrangement of its mineral components, reveals the lowest values of all the parameters analysed.
