How to Determine the Quality of Ceramic Tiles

How do you determine the quality of ceramic tiles?

  1. Size Variation
  2. Warpage
  3. Wear Resistance and Water Absorption


When thinking about purchasing the best ceramic tiles in the Philippines, you should always inspect what you’re buying and know some information about its brand before you start purchasing. It’s important to the right qualities of ceramic tiles and a few details of the manufacturing process, in order to know how well the tiles were made. Here are a few things to look out for in order to determine the quality of ceramic tiles.


Size Variation

Size Variation

The best tiles ceramic tiles in the Philippines will always be consistent with every single tile’s dimensions. Poor craft can be easily spotted with inconsistent or uneven tile joint dimensions. These irregularities are due to discrepancies with a single or multiple steps in the process of creating the tile.

Commonly, anomalies may occur during the firing process; when the tiles are being fired at the kiln, the bisques may have a tendency to shrink. This shrinkage may result in uneven tiles dimensions. That is why it is of utmost importance to keep the atmosphere of the kiln controlled.

A solution to these irregularities and inconsistencies is to make use of rectified tiles. These rectified tiles may involve a few extra steps in the creation of the tiles. The extra steps are cutting and grinding; which happens after firing the tiles in the kiln. Many floor tiles for sale with even edges may have gone through this extra step. You’ll notice this right away if you observe that the edges are straighter which make for an aesthetically satisfying and pleasant tile.




Warpage is one of the things you need to look out for. This is the curvature of the tile’s face, it could either be convex or concave in shape. Of course, you would want your tiles to be perfectly leveled with one another. Warpages on your floor tiles for sale can be assessed with a depth gauge. What a depth gauge does is measure lippage or unevenness between the two tiles.

High quality tiles, such as the FC Tile’s 60×60 L6333, every process, from the first to the last, are done seamlessly. Tiles of poor craftsmanship that have a problem with warpage mean that something has gone wrong in the firing and cooling process of the ceramic tiles. Though most ceramic tiles will show signs of some warpage, it wouldn’t be as dramatic if done expertly.

The warpage is measured in two different ways: Edge warpage and diagonal warpage. The former is measured at the center of a tile’s edge while the latter is measured at the center most part of the tile. What you’ll be addressing when measuring warpage is the percentage of the tile’s linear dimensions.

Along with warpage, lippage is another cause of inferior craftsmanship. Lippage refers to when a tile’s edge is higher than the adjacent tile. This gives off an unsatisfying appearance of uneven tiles and a ragged finish.

This may be a potential health hazard to individuals, especially when walking bare-footed. Not only does this cause discomfort, but lippage often impedes water flow and puts people at risk by slipping.


Wear Resistance and Water Absorption

Wear Resistance And Water Absorption

When it comes to making resilient and hardy tiles, the first step to creating tiles needs to be done with precision. This is the gathering and batching of the raw materials. The combination of raw materials used will ultimately affect the density of the finished products; subsequently, this also influences the water absorption rate of the tiles.

The choice of raw materials will be used to determine the overall degree of hardness of the tile. Ceramic tiles are made from clay of different mineral content and varying properties in order to get the ideal combination of hardiness and design. Subjecting the mixture of clay to high temperatures tests the tile’s measurement of hardiness.

From a rating of 1 being the softest and 10 being the hardest, values from 4 to 6 are perfect for residential applications while tiles with a value of 7 and above are more suited for commercial applications, typically in areas subjected to heavy traffic. The final hardness of the tiles will be determined by the mixture of mineral content found in the tiles.

There are some defects that may occur in the tile that compromises its overall structure, leading to poor wear resistance and water absorption. Crazing is a defect in a tile where thin cracks form at the surface of the tile. This is caused by the expansion and contraction of the glaze and the bisque.

Another cause of crazing could also stem from the firing process. In the kiln, the tiles could be subjected to thermal shock; this happens when there is a sudden change in temperature during the firing process. When temperatures are brought up too soon or cooled down quickly.
