Ceramic and vitrified/porcelain tiles come under the category of ceramic tiles whereas vitrified tiles are known non-porous ceramic tiles.
Classification of tiles
The classifications of tiles are mostly based on their method of manufacturing, water absorption qualities, choice of application, area of usage, strength, etc. The most commonly used tiles are ceramic and vitrified tiles or porcelain tiles. The classification criteria are the percentage of water absorption which is around 4-5% in ceramic tiles where as it is below 0.5 % for vitrified tiles.

Reference IS CODE = IS 15622 – 2017
| Water absorption | 3% -6% |
| Breaking strength | Minimum – 1000 N |
| Modulus of rupture | 20 to 30 N/mm2 |
| Scratch hardness (Moh scale) | 4 minimum |
These types of tiles are not preferred in high traffic areas and outdoors due to their low density and high water-absorbing qualities.
Ceramic tile manufacturing process
Ceramic tiles are manufactured from natural clay, sand, and water. The ingredients are ground and mixed with water in the right proportions to form a paste. The mix is pressed or extruded to form a tile and passed through a drying process for imparting the strength. The pattern, design, or textures are digitally printed on the surface and sprayed with a glaze powder before passing through the kiln for the firing process.
In the first stage, the tiles are subjected to medium temperatures for removing the water content, and in the next stage, the kiln temperature is raised to 1000-1200 degrees. In high temperature, the glaze fuses and forms a transparent layer on the tile surface. Further, the tiles are subjected to a curing process before exposure to ambient temperature to avoid breakage.
Type of ceramic tiles
Ceramic tiles are classified into wall tiles and floor tiles. They are available in glazed and un-glazed varieties. Ceramic wall tiles are normally less durable than vitrified tile which is designed specifically for flooring. Most wall tile is glazed with a semi-gloss or matt surface. The glazed surface has a very low slip resistance and becomes slippery when wet. Therefore, glazed wall tile is much more suited for wall or counter-top applications rather than floors. Floor tiles are available in anti-skid and matt finishes which are used for flooring, bathrooms, and wet areas.

Disadvantages of Ceramic tiles
Easy to care for and available in hundreds of styles, nonetheless there are disadvantages that should be taken into consideration when a homeowner is choosing ceramic installation for the home. On getting clarity on the drawbacks we can make an easy choice.
Tile joints
Ceramic tiles are stain-resistant and water-resistant. But Grout lines are suspectable to moisture if not sealed properly. Care should be taken in choosing the sealant and sealing of grout lines. The tile joints have to be periodically sealed to restrict moisture entry and increase the tile life.
For installation, we need skilled workers to maintain the level and alignment. A proper laying is the most important factor deciding the tile life.
Ceramic tiles got a wide variety of colours and shades and the shades’ textures and style and choice of interiors tend to change with time. Once a ceramic tile is installed, replacing it will be a messy and costly option. Replacing a broken tile needs highly skilled workers and tools or else chance of breakage of nearby tiles will happen.
