Curious about what is porcelain tiles made of? Porcelain tiles are crafted from a blend of fine clay and natural minerals like quartz, silica, and feldspar, all fired at high temperatures to create a durable, low-porosity material.

These tiles are known for their strength, aesthetic appeal, and versatility in both indoor and outdoor spaces. In this article, we'll delve into the detailed process of how porcelain tiles are made, from the raw materials used to the final finishing touches.

Join us as we explore the fascinating world of porcelain tiles and their many benefits for your outdoor space.

What Are Porcelain Tiles Made of?

Porcelain tiles are crafted from a refined blend of natural materials that undergo a meticulous manufacturing process to achieve their renowned durability and aesthetic appeal. Let's break down the core components and the journey they undergo to become the stunning tiles we love:

The Raw Materials

The primary ingredient in porcelain tiles is a fine, high-quality clay, often mixed with other natural minerals such as quartz, silica, and feldspar. According to our research, these materials are selected for their properties that contribute to the tile's strength and durability.

This combination and manufacturing process means that even though porcelain contains natural elements, natural stone and porcelain are different in terms of flooring.

Mixing And Grinding

The first step in the production process involves blending these raw materials with water to form a mixture known as slip. This mixture is then ground in a ball mill to a fine, consistent texture. In our experience, the inclusion of tiny beads helps to break down the particles, ensuring a uniform blend.

Forming And Drying

The slip is then dried to remove excess moisture, resulting in a powdered form. This powder is pressed into moulds under high pressure to form the tile shape. The high pressure increases the density of the tiles, enhancing their strength and reducing porosity.

Adding Colours And Designs

Once the tiles have taken shape, colours and designs can be added. This is an optional step but is crucial for creating the diverse range of porcelain tiles available.

The designs are applied using advanced printing techniques, allowing for intricate patterns that can mimic natural stone, wood, or other materials.

The pressed tiles are then fired in a kiln at temperatures reaching up to 1200°C (about 2200°F). This high-temperature firing process vitrifies the tiles, giving them their characteristic hardness, durability, and low water absorption rate (less than 0.5%).

After putting it to the test, we've found that this is what makes our porcelain paving ideal for both indoor and outdoor use, as they can withstand heavy traffic and various weather conditions. So, if you're wondering are outdoor porcelain tiles slippery, then you can rest assured that they're perfect for outdoor use even in rainy weather.

This firing also makes them highly durable. Because of their longevity, you won't need to replace them for many years, making porcelain sustainability a fantastic option.

Polishing And Finishing

After firing, the tiles may undergo polishing to achieve a glossy finish, or they can be left matte, depending on the desired look. Some tiles are also glazed to add an extra layer of protection and to enhance their aesthetic appeal.


Porcelain tiles are a remarkable blend of fine clay and minerals like quartz, silica, and feldspar, fired at high temperatures to create a durable, low-porosity product.

They offer a perfect combination of strength, aesthetic variety, and versatility, making them ideal for both indoor and outdoor use. Understanding what porcelain tiles are made of reveals the advanced craftsmanship and technology behind their production.

From their robust nature to their elegant designs, porcelain tiles are a valuable addition to any space. Ready to transform your outdoor area? Explore our range at Ovaeda and find the perfect porcelain tiles for your project today!
