The Science Behind Vitrified Tiles: How They Are Made

There are various types of tiles available in the market, like granite, stone, vitrified, and ceramic. Out of these, vitrified tiles are the most preferred type of tiles by homeowners and designers alike. Vitrified tiles are made through a very interesting process.

In this blog, we will explain the manufacturing process of vitrified tiles. Before visiting a tile company in Morbi, take a moment to read this blog and learn how vitrified tiles are made.

Manufacturing Process of Vitrified Tiles

Let us understand how vitrified tiles are made.

Mixing

First, the raw materials, such as silica, quartz, feldspar, and refined clay, are carefully selected. These ingredients are then ground into a fine powder and mixed with water to form a slurry, which ensures a consistent blend. These materials are what give vitrified tiles their strength and glass-like properties.

Spray Drying

The slurry then goes through a spray drying process where hot air evaporates the excess moisture. This converts the slurry into fine, free-flowing granules with a uniform size and controlled moisture content. This process makes them ideal for pressing into tile form.

Pressing & Shaping

The granules are then made into flat tile shapes by transferring to large hydraulic presses that apply extremely high pressure on them. This pressing ensures a dense, air-free tile body that is strong and durable.

Drying

The freshly pressed tiles are passed through dryers, where controlled heat removes any remaining moisture and stabilises the tiles to prevent any cracks or warping from happening later.

High-Temperature Firing (Vitrification)

The dried tiles are then fired in kilns at very high temperatures (between 1200°C and 1300°C). During the firing process, the raw materials melt and undergo a process called vitrification, where they fuse to form a glass-like crystalline structure.

Polishing & Finishing

The tiles undergo surface treatment once they are cooled. This varies depending on the finish desired. For example, polished vitrified tiles (PVT) are machine-polished to achieve a mirror-like shine, whereas a matte finish is left natural or treated lightly by the vitrified tiles manufacturer.
