Real smooth with a minimal porosity. Distinguished by mirror finish, with a darker tone of the stone than in other surface treatments, with no presence of scratch.
By means of abrasion with rotary heads for decreasing devastation, that polishes stone gradually in order to reach the minimum porosity level or closed pore finish.
Because of the closed pore, it is the easiest to clean finish, and the least absorbing liquids, so it is more difficult to get stained by external aggressions such as water, oil, acids, etc. It is very tough, but the absence of porosity and texture makes it the least anti-slip finish.
