Just a little ceramic information to share as a potter. Vitrified simply means the clay has become glass like by being fired to its proper maturing temperature. Usually ceramic tile means it is a lower temperature clay like earthenware or terra cotta. Porcelain is fired to the highest temperature and is more vitrified if you will. This usually means it is less porous to to absorb water and harder. Low fired ceramics with glazes much darker or lighter than the clay body will show chips easier. Rectified has to do with making the edges precise enough to fit smoothly together for less grout lines. So porcelain cost more to produce but it is more sturdy. All clay tiles should be vitrified.

Do you mean marble versus porcelaine tile?

Hi, I love the look of marbles as kitchen counter tops but am hesitant because of the problems with staining. There are lots of vitrifed glazed floor tiles which give beautiful marble look. Is it advisable to use them as kitchen counter tops? Since they come in 4x2 ft size, the number of joints will be less. Will they be chemically safe around food? Thanks in advance
