Difference between Ceramic Vitrified GVT PGVT full body double charge and soluble salt tiles
The manufactured tiles are broadly divided into categories as per their water absorption property.

Water absorption properties are played during manufacturing of tile, the clay use for manufacturing ceramic and vitrified tiles are same.

In order to understand how tiles are classified, better to visit below thread which describe the manufacturing process of tile in detail.
Ceramic and Vitrified Tile Manufacturing Process - Civil4M

First we will understand the basic difference between ceramic tiles and vitrified tiles.

Ceramic Tiles - This tiles have high water absorption property and low strength due to high porosity in it. We can make almost any kind of design on it either by printing with digital or rotary drum type printer. We can use this tile on wall as well as on floors.

Vitrified Tiles - it have less water absorption due to moulding the green tile at high pressures which results into more dense structure and less voids in the tile leading to less water absorption value.
Vitrified tiles have quartz and feldspar on it which after heating forms a glass like hard layer on it and need polishing.

Vitrified tiles are also called as porcelain tiles.

Vitrified tiles are further classified in many categories as per their front finish application methodology such as
Soluble Salt
Double Charge
Full Body
Glaze Vitrified (GVT)
Polish Glaze Vitrified (PGVT)

and you may here many names of it and all are given as per their topping / finish layer application.

Soluble Salt Tiles - A single color layer of soluble salts is applied on its surface which penetrates its color inside the body of tile up to great extend (3 to 4mm). Over a period of time the color goes dull. as its a single color tile the making more designs are not possible in it so technology moved further to make more designs and Double charge tiles are came into picture.

Double Charge Tiles - In double charge tiles, if you had seen tile manufacturing process article you might understand more better, how they are manufactured. To produce a double charged tile during manufacturing at pressing machine assembly first a body powder / clay is filled in the mould and then on top of it combination of two powder/ mineral / pigment is filled in design shap and the tile is press again in pressing machine. so it becomes a double charged which have design imprints till the depth of top layer of it. as its again cant make much combination so designing and variety is restricted in this type too, to overcome the issue a glaze vitrified tiles are came into picture.

Full Body - As per the demands of people around the world which says, at high traffic areas when tiles get chip out we sees the brown or white body of tile which makes ugly impression so is there any solution for it. To overcome the issue designer made a new technology called full body tiles in which a color pigment is added in the body of tile which make it look like same color that of top. So when tile gets damaged it wont look odd and can serve further more period without replacement. The problem in the full body tile is, we can only produce a darker color tiles with this technology due to color property of clay and also it adds additional cost.

Glaze Vitrified (GVT)- This is same like ceramic tiles but have more strength and lessor water absorption in it. the current market demand and architects requirement for making homes more beautiful took GVT in limelight. it is coated with glaze and same way like ceramic digital printing is done on top of it as per the requirement (You can have your photo printed tiles)

Polish Glaze Vitrified tiles (PGVT) - its a same like GVT with polish on top of it to make it more shiner.


So when you say a tile - there is always a ceramic or vitrified tile. the selection of which type vitrified tile to be use is purely depends on type of work and its durability requirement.


You can fix wall tiles on floor but can't fix floor tiles on wall. (if you want to fix floor tiles on wall, kindly do use adhesive for fixing it)

Vitrified tiles (floor tiles) have lesser voids on its back also do have very less water absorption in it, fixing it with cement paste does not ensure the bonding of it to wall.
