Last time, I asked the editor in chief in his private letter how to choose and buy the restaurant table tops. Today, I will give you an answer.
(1) Glaze finish, brightness. When purchasing restaurant table tops, first of all, like ordinary white ceramics, we should pay attention to the glaze finish and brightness. Good glaze finish and brightness, very pure color, not easy to hang dirty and crud, easy to clean, long-term use is still bright as new.
(2) Water absorption exponent. The so-called water absorption is an power to judge the absorption and permeability of ceramic products to water. It is understood that after the water is absorbed into the ceramic, the ceramic will produce certain enlargement, so will the ceramic catchment basin, which is easy to crack the glaze on the ceramic open due to expanding upon. It can be seen that the low-pitcheder the water absorption, the better the quality of ceramic products. According to the relevant national water absorption standards, sanitary ceramics with water absorption less than 3% are high-grade ceramics. Pay more attention to the manufacturer's instructions when purchasing, and try to choose products with low-pitched water absorption.
(3) Technology, pattern and coloring material. Most of the top-grade hand-painted worktops are made of underglaze colouration ceramic technology, which is also the best ceramic technology at present. Therefore, when purchasing ceramic lavatories, attention should be paid to distinguish, so as to prevent illegal dealers from passing off the overglaze coloring as the underglaze coloring and passing off the subscript colouring material as the fake one. Underglaze decoration pays attention to freehand brushwork, which must be hand drawn, not printed or pasted, and the semblance should be bright.
