What is the deferent of Porcelain and fully vitrified tiles?
There are no porcelain tiles.Porcelain is an expensive matter,used in dignified quality table ware,not for tiles.
Vitrified tiles are most used for flooring,although they hold other uses.In these tiles,the body is "once fired" at extremely high temperature.This causes the materials to flux and fuse to build a vitreous surface.
Porcelain tiles are stoneware tiles with a dampen absorption rate of smaller amount than 0.5 percent that are used to cover floors and walls. They can either be unglazed or glazed.
Vitrified tile is a tile which have been processed within such a way that it have very greatly low porosity (and water absorption) which trade name it stain resistant and very strong.
Vitrified tiles are unglazed tiles. Their polish is achieve by very thorny materials and they are very exceedingly strong and durable, whereas porcelano tiles are glazed tiles and their durability is as good as the durability of the polish applied over them. And glaze are not unyielding and scratch resistant as the vitrified tiles.
Answers: Are u asking the difference between procelain and vitrified tiles.
If yes, then
Porcelain tiles enjoy a glaze(layering) of a glassy things over them. This makes them as strong as the polish material and protects from scratch. These are less expensive and smaller quantity durable then the vitrified tiles.
Vitrified tiles are prepared by creation of 'glass phase inside the tiles'. In other words, they enjoy glassy stuff inside next. This gives after more strength and durability. They are expensive also.
