SLUBBING
Is a process that works thermically on the surface of the materials, making it scabra.
The flame works at high temperature by vesting the surface to treat, which undergoes to a termal shock around 600°c.
This effect, combined with the immediate water cooling of the surface causes an expansion phenomenon and thermal gap. of quartz and silicon, highlighting the material’s natural color and texture. The treated surfaces therefore seem vetrified, becoming more resistant to atmospheric agents. The flame treatment is applicable to all granites and several marbles.
