A Brief History of Porcelain

Choosing a Quality Porcelain Tile - Tile Showcase (1)

The word “porcelain” may bring to mind fine, white china or delicate pottery that is nearly translucent. This is because the word porcelain originally meant a type of clay that was made of kaolin or that had a high kaolin content.

Porcelain tiles have been around for thousands of years. They date back to 4,000BC in Egypt and were produced for hundreds of years in China, with the 15th century seeing a lot of advancements in how the tiles were made. These tiles were called porcelain because they contained kaolin.

Eventually, porcelain tiles became synonymous with hard, long wearing tiles that often had color going through the tile. Unlike ceramic tile, which always has a glaze, porcelain was thought to be a harder, less porous, and more durable material. Because this described many types of tile, though, and it was difficult for consumers to tell just how porous or durable a tile was, a third party was established to create a standard.

Today, the Porcelain Tile Certification Agency tests tiles to determine if they are actually porcelain, which they have defined as a ceramic (clay based) tile with a water absorption rate of less than 0.5%. The tiles may be made of compressed clay dust or extruded clay, and most are fired to very high temperatures to achieve their durability and low absorption rate. This process is often referred to as vitrification, and the resulting tiles are considered “vitrified”. During this process, the tile is brought to higher and higher temperatures to drive out moisture, and transform the elements of the tile so that they flow together and fill the spaces between the clay. This is what gives a tile a low-absorption rate, and renders it stain resistant. If a tile is not certified by the PTCA, it cannot truly be considered porcelain, even if a retailer calls it that.

Visual Inspection: Carefully examine the tiles for any visible defects or imperfections. Check for pinholes, color inconsistencies, cracks, or irregularities in the surface. Premium quality tiles should exhibit a flawless appearance, while standard quality tiles may have minor flaws.

What is the best thickness for porcelain tile? ›

Tile Thickness

The vast majority of porcelain tiles are 6mm to 10mm thick and a tile in this range will serve most purposes. Wall tiles typically range from 6 to 10mm thick. Mosaics and decorative wall products also range from 6 to 10mm thick to make combining them easier.

How can you tell if porcelain tile is glazed? ›

Which is better, glazed or polished porcelain tiles? ›

Because glazed tiles are more beautiful and more transparent than polished tiles, the price is also slightly more expensive. The wear resistance and hardness of polished tiles are relatively high, while the surface of glazed tiles is transparent and bright, in contrast, the wear resistance is poor.

How to identify premium quality tiles? ›

Premium Quality Tiles are 100% perfect. There are no manufacturing defects in them and they are pretty much engineered correctly without any defects.

Is there a difference between cheap and expensive tiles? ›

Expensive tiles often offer a wider range of designs, textures, and finishes. Premium options may include unique patterns, sophisticated glazes, and high-end aesthetic features.

Why are some porcelain tiles so cheap? ›

As expected, a higher MOHS rating typically commands a higher price. A tile could be less costly if its clay body is brittle or not tinted to match its glaze. Through-body and color-body porcelains tend to be pricier than glazed porcelains since the clay is colored to harmonize with the surface glaze.

How to check porcelain tiles? ›

ANSWER - The general rule of thumb for whether a ceramic tile is a porcelain type of ceramic tile or another ceramic tile body type is that the porcelain tile body cannot have an absorption rate greater than 1/2 of 1% (0.5%). If the tile body readily absorbs water then it certainly isn't porcelain.

Why are porcelain tiles different prices? ›

Tile Design

However, there are a number of factors that can affect the price of porcelain tiles such as the manufacturer, the country of origin, the depth/quality of the printing process, etc. But the thing that affects tile pricing the most is the design.
