We are manufacturers, exporter and suppliers of steel Grey, Black Pearl granite slabs/tiles from India. Also we have with us the best black granites, black galaxy granites.
The technical term is “Thermal Finish”. This is the
process where slabs of ‘certain types’ of granite go
through a machine (it can also be done by hand) where
high temperature torch heads heat up the crystals until
they pop, leaving the granite with a heavy textured
surface. Granite with large crystals are more coarse
than granite with very fine crystals.
This ‘flamed finish’ is VERY porous. This technique is most often used for commercial sidewalks to provide a slip resistant sidewalk, stair case steps or courtyard finish. This type of finish requires additional treatment with sealers to prevent stains. The Flamed Finish may be further treated for leather finish, Antique finish and lappatura finish.
