The absorption rate is how porous a material is. The more absorbent a material is the more likely it is to stain as well as how much cracking damage it suffers during freezing conditions. There are four different levels of absorption when it comes to natural tiles. Non-vitreous is the highest absorption and should not be used in any environment that can become damp. Semi-vitreous are less absorbent but will require more maintenance the more liquid is exposed to them. Vitreous is the standard level of absorption and is considered most appropriate to be placed in areas with low to mid indoor or outdoor traffic. Impervious is the most resistant when it comes to the absorptions of liquids and are the easiest to maintain and clean.
Always take care to wear hand and eye protection as well as suitable clothing and remove and power sockets or electrical equipment that is likely to get wet in the process. When marking a cut line on a natural stone tile you may prefer to use a crayon as opposed to a pencil which is likely to not make a significant mark on the tile. Take care to go extra slow when reaching the end of your cut as if you go too fast and force the tile through it is likely to break rendering it difficult to use. If you are cutting a particularly large tile try to get someone to help you steady the tile as you cut since the weight of either piece of tile can start to pull the whole piece apart - encouraging a snap - as you advance through the tile.
One reason for this is because stone is a very strong material that is more difficult to cut than a wood board or even a ceramic tile which would be scored and snapped. In addition to this you may need to prepare the surface of the sub-floor upon which your tiles will be laid if it is uneven or cracked. This can be done in most cases with a good quality self-leveling compound available from all respectable tile and flooring specialists. When preparing natural stone tiles for laying be sure to spend time inspecting them both for chips and surface scratches. Typically natural stone tiles will arrive with a light wax coating to protect them from potential damage in transit.
