Vitrified Tile Body & Design – How They Are Made

Vitrified Tile Body & Design – Complete Manufacturing Guide

Vitrified tiles are one of the strongest and most popular tiles used today.
They are widely used in homes, offices, malls, hotels, and commercial projects because of their high strength, low water absorption, and premium designs.

But many people ask:
👉 How is vitrified tile body made?
👉 How do vitrified tile designs come on the surface?

Let’s understand the full process step by step, in simple language.

⭐ 1. What Is a Vitrified Tile Body?

A vitrified tile body is a dense, glass-like tile body made from a special mix of minerals.
During manufacturing, the tile body becomes non-porous, which means it absorbs almost no water.

That’s why vitrified tiles are:
✔ Very strong
✔ Long-lasting
✔ Water-resistant
✔ Suitable for floors and heavy-use areas

🏭 2. Raw Materials Used in Vitrified Tiles

Vitrified tiles are made using refined materials such as:

China clay

Silica

Quartz

Feldspar

Other minerals

These materials help create a hard and compact tile body.

⚙️ 3. Vitrified Tile Body Manufacturing Process (Step by Step)

🔹 Step 1: Raw Material Mixing

All raw materials are mixed with water to create a fine slurry.
This slurry is filtered to remove impurities.

🔹 Step 2: Spray Drying

The slurry is passed through a spray dryer, where water evaporates.
The result is fine, uniform powder, which forms the tile body.

🔹 Step 3: High-Pressure Pressing

The powder is pressed in moulds under very high pressure.
This creates the tile’s exact size, thickness, and density.

High pressure is the main reason vitrified tiles are so strong.

🔹 Step 4: Drying

The pressed tiles are dried to remove leftover moisture.
This step prevents cracks during firing.

🎨 4. How Designs Are Created on Vitrified Tiles

Modern vitrified tiles use advanced digital printing technology.

🔹 Step 5: Surface Preparation

The tile surface is prepared depending on tile type:

Polished

Matt

Satin

Carving / texture

🔹 Step 6: Digital Printing

High-resolution inkjet printers print designs directly on the tile surface.

Popular designs include:

Marble look

Stone look

Wooden look

Onyx designs

Concrete & cement looks

These printers use special ceramic inks that fuse permanently with the tile.

🔹 Step 7: Protective Coating

A protective layer is added to improve:
✔ Scratch resistance
✔ Stain resistance
✔ Design durability

🔥 5. Kiln Firing (The Vitrification Process)

Tiles are fired in a kiln at 1200–1250°C.

During this process:
✔ Minerals melt and fuse
✔ Tile body becomes glass-like
✔ Water absorption drops below 0.5%
✔ Design becomes permanent
✔ Tile gains maximum strength

This high-temperature firing is called vitrification.

🧪 6. Polishing & Surface Finishing (Optional)

Some vitrified tiles go through polishing machines to create:

High-gloss finish

Mirror-like surface

Others are finished as:

Matt

Satin

Carving / textured

📦 7. Quality Checking & Packing

Each tile is tested for:

Size accuracy

Flatness

Shade consistency

Surface defects

Strength

Tiles are then sorted by shade, packed, and dispatched.

🧱 Types of Vitrified Tiles Based on Body & Design

Double Charged Vitrified Tiles

Soluble Salt Tiles

GVT (Glazed Vitrified Tiles)

PGVT (Polished Glazed Vitrified Tiles)

Each type offers different design depth, strength, and finish.

🆚 Vitrified Body vs Ceramic Body (Quick Comparison)

Vitrified tiles are made using advanced technology, refined raw materials, and high-temperature firing.
Their body is extremely strong, and their designs are created using digital printing, making them both durable and beautiful.

That’s why vitrified tiles are the first choice for modern flooring and large projects.

✨ Vitrified tiles = Strong body + Premium design + Long life

Understanding the body and design process helps you choose the right vitrified tile for the right place.
