What is travertine (2)

A travertine quarry is the place where this stone is extracted from. Most quarries are huge and look like deep, enormous holes. The travertine is broken into blocks which are then transported to factories for further cutting and processing. After the blocks are cut into slabs, paving tiles, mosaics etc., they are given different types of finishes.

What is the difference between first class, commercial or type A travertine?

Travertine's class or category is usually determined by the percentage of holes inside the stone: the fewer the orifices, the higher the quality. Travertine slabs with a high percentage of holes fall into the commercial category. Tiles with the fewest number of holes are considered class A. There is something else that must be taken into account. Some travertine slabs are filled and honed, so their holes have been covered with a special filler. The difference between first class and commercial travertine is determined be the quantity of filler used to fill the stone's orifices. 
A honed travertine tile which has a lot of filled orifices is of lower quality than one which has undertaken a minimum filling.
The filler used has the same colour as the travertine so it is very hard to notice it, which means that even in the case of a commercial quality travertine, the aspect of the stone is quite pleasant. Obviously, the difference in quality generates a difference in pricing.
