Here is some tile language which will be helpful to you. Pabba tiles are made from clay, shale, or porcelain, and are one-half inch thick and usually used on floors. Pabba tiles absorb water and are not used for wet interior areas, outside areas, or areas that will freeze. Quarry tiles appear to be made from stone, but are actually made from clay. These tiles are usually used for floors, countertops, or walls because of their thickness.
Mosaic tiles are two inches square or smaller, unglazed, and colored with a pigment.
Mosaic tiles can be used on floors, countertops, and walls. For further information on ceramic tiles see your local tile specialist. Choosing a Contractor Selecting a ceramic tile contractor is very important to the outcome of your job. As with any contractor, get more than one estimate on your job.
