quality level of ceramics; The first step when buying them
You must have heard from tile and ceramic sellers that this product is first class and has a higher price than others. The story is that all tiles and ceramics are divided into different grades in factories and after leaving the production line, based on various factors and their final condition. In general, tiles and ceramics are divided into grades one to four after being produced in the factory and then sold to the market. Now the question is, on what basis is ceramic grade recognized in factories? In the following, we will introduce you to the grading of ceramic tiles.
Detection of first-class ceramic tiles
After the tiles and ceramics were removed from the production line; If there are no defects in their appearance and the glaze surface and their edges are healthy; They are placed in the first grade level. This type of products because they have very high quality; They will be more expensive.
Detection of second grade ceramic tiles
If defects are seen after the production of ceramic tiles; They are placed at the second grade level. The diagnosis of the ceramic grade at this stage is determined based on the following defects.
- If there is only one spot on the glazed edges of the products after they are taken out and the surface is not covered with glaze; The desired product is placed at the second grade level. It should also be noted that the dimensions of this edge should be at most 2 to 3 mm.
- If one or two moles are observed at a distance of 2 cm from the glazed surface of the product and their diameter is about half a millimeter; They are divided at the second grade level.
Identifying grade three ceramic tiles
As the grade of tiles and ceramics increases; It means that more important defects have been seen in their appearance. To recognize the grading of ceramic tiles at level three, there must be a spot on their glazed surface. Pay attention that this mole must have a diameter of 3 mm so that ceramic tiles can be placed on this level.
Detection of grade four ceramic tiles
As you have seen; Determining the grade of ceramic has special conditions and is based on certain factors. But in the meantime, it is a bit more complicated to distinguish fourth-grade ceramic tiles compared to other grades. Since this type of tiles have a higher grade; More flaws should be expected. The things we mention below; If they are present on the produced tiles and ceramics; They are placed in the fourth degree.
- If there is a gap of 3 x 5 mm in one of the corners of the tile or ceramic.
- If there is a chip or a mole on the tile or ceramic.
- If the gap in the corner of the tile or ceramic is 2 x 2 and the mole on its glazed surface is at most half a millimeter in diameter.
- If there is an unglazed spot measuring 3 x 10 mm on the edges of the product.
- If the product has two unglazed points measuring 2 x 5 mm.
- If the tile or ceramic has 2 or 3 moles of half a millimeter.
Even though the grade of ceramic tiles at level four is determined using these characteristics, it is better to know that the quality of this category of products is random. That is, you may see better quality when buying a fourth-grade product, but you may see low quality when you buy another fourth-grade product.
Determining the grade of ceramic tiles from the carton
It is also possible to distinguish the grade of ceramics and tiles in other ways. You can determine the quality of these products to a large extent based on the type of carton. Usually, white cartons with the words “This product is not covered by Iran’s 25 Standard Law” written on them; The tiles and ceramics are grade four. Large factories and productions that operate in the field of tile and ceramic production; They must include the grade of the products on their cartons or packaging so that buyers can choose the desired product more easily.

Ceramic and tile grading is usually done in factories, but by using a series of appropriate solutions, you can determine the grading of ceramic and tile. The simple tests we introduce below; The most important solutions are to determine the grade of tiles and ceramics.
- Place tiles or ceramics together; if the seam between them is the same from top to bottom; The desired product is of very high quality.
- The second solution; is to stack the ceramics from the glazed side. After doing this, press one of the edges with your finger. If the ceramics were not loose; It can be said that they are of high quality.
- The third solution; It is a contraction and expansion test. To perform this test, first place the ceramic in the refrigerator for a few hours and then immediately put it in boiling water. If the ceramic glaze survives this work; Know that you have purchased a quality product.
