When choosing items of sanitary ceramics, a sink, toilet bowl or bidet, the majority of buyers stop in confusion before two mysterious definitions of "sanfarfor" and "sanfayans".What are the differences? Which of the materials is more practical and durable? And why plumbing, marked with the word "sanfayans", is cheaper than manufactured from sanfarfor.

By the appearance of the product of these materials is difficult to distinguish, and under the force except that specialists. Faience, as well as porcelain - types of ceramics. The difference between them is not great. The main differences - in the recipe and production technology.

White clay - the basis of sanitary ceramics

The faience and porcelain is made from the same white clay. But the additional components they have different. Sanitary is obtained from pure kaolin with a small addition of quartz. And in the manufacture of sanitary ceramics, clay is mixed with quartz and feldspar. The material is more durable and less porous. Although it can not be said that the sanitary ware is fragile. It also has a high hardness, although slightly inferior to the Sanfarfor.

But products made of sanitary faience are more elegant. Toilet bowls having exquisite shapes and sophisticated architecture, as a rule, are faience. Porcelain plumbing is laconic and simpler.

The firing technology has a value of

Burn products from sanitary porcelain and faience also in different ways. The process of firing a sanitary faience passes in one stage, but has several steps. The time and temperature for this material are the principal categories.

Degrees in the furnace increase to a thousandth mark gradually. Then the product is kept, as slowly lowering the temperature. If there is a sharp jump, organic compounds will burn. As a result, the object will lose the specified shape, color and strength, and also hidden defects may appear.

The firing of items from the sanitary porcelain takes place in two stages, thereby reducing the porosity of the product and obtaining greater strength.

Frosting."Reinforcement" of clay

Sanitary ware from sanitary faience, as well as sanitary-ceramics, is covered by mandatory glaze and dirt-repellent composition. Because clay has the ability to absorb moisture and absorb odors. And for items of sanitary engineering this is unacceptable. Thanks to the glazing of the product from the sanitary ceramics, they obtain excellent performance characteristics.

The composition of the glaze from one manufacturer and for the sanitary ceramics, and for sanitary ware, as a rule, is identical. That is why it is so difficult to distinguish products from these materials.

Question of the price

Traditionally sanitary ware plumbing is cheaper than sanfarforovaya. This is due to the simpler composition of the material and the less costly production process. However, this does not mean that the toilet bowls or shells of faience are worse. If they are inferior in some respects to products made of porcelain, it is insignificant. And when operating, the difference is unlikely to be noticeable.

In addition, the price of faience plumbing of one manufacturer can several times exceed the cost of another porcelain. However, this is already a matter of brand awareness and company philosophy, not materials at all.
