The answer to this question really depends on where the block will be used. Currently, more than 80% of the tiles used for floors are porcelain tiles, while most of the tiles used for walls, backsplashes and countertops are ceramic tiles. External surfaces, such as patios, are usually paving stones or porcelain tiles.
The reasons have to do with the durability in the case of porcelain tiles. Although the options of price, color and design have a lot to do with the ceramic tiles selected for walls, backsplashes and countertops.
Ceramic tiles have existed for thousands of years. This is a testament to its durability and versatility. The body of the tile (called bisque) is made of clay and other minerals. When combined, these raw materials give the soup its strength and stability.
The quality of the tile has to do with the quality of the manufacturer, the density of the clay and the resistance to breakage of the tile. Porcelain is simply a thinner type of clay and makes a harder tile body.
Porcelain tiles have a lower rate of water absorption than ceramic tiles because porcelain tiles are very dense. When baked at 1800 degrees, a surface color is created on the porcelain tiles. But when it is baked at 2200 degrees, the color passes through the entire body of the tile.
Then, if they splinter, it will not appear as much as on a tile with only a surface coloration. Porcelain can be used outdoors, even in areas where the temperature is below the freezing point. They are considered “resistant to freezing” (not freezing proof). This makes the porcelain suitable for patios, since the elements do not damage it.
Many tiles have a glaze applied to the surface. Unglazed tiles have a greater resistance to sliding than enameled tiles and, therefore, are recommended for areas subject to water. The advantages of mosaics are that you get an unlimited range of colors and a greater resistance to stains. Unglazed tiles provide better wear and greater slip resistance.
It is possible to find tiles that have abrasive sand on their surface, which substantially reduces the possibility of sliding. These cards are very suitable for both public and outdoor areas. There is another test process for enamel only. This is called Mohs test and determines the hardness (scratch resistance) of the enamel.
As you can see, there are many quality levels that determine the different price levels. In general, you get what you pay for and China tiles are well known as the cheapest. However, there is always the possibility that you are misinformed about the block you are buying. It is important to deal with the providers that will give you the correct story and will have your best interest in mind when suggesting blocks for your home.
