1. Health and environmental protection standard is one of the most important reference index when purchasing a countertop. Because in the practice of daily life, countertop contacts with food and human body directly, it affects the people’s food sanitation and health directly.

2. Identification of the material appearance from surface texture: in terms of the manufacturing process, quartz stone belongs to artificial stone, but in terms of the texture, excellent quartz stone with strong natural sense is nearly similar to the natural stone, which is one of the important standards in industrial technical standard. The quartz stone produced by outdated manufacturing facilities and technology has an more strong appearance of plastic resin and artificial mark.

①Interior quality
Antibacterial: Nonporous surface and endogenous substance with the high quality of antibiotics help prevent the breeding and spreading of bacteria and enzymes. The imitative quartz stone having not passed the strict international certification standard would have not this function at all.

②Density/penetration resistance: the surface and interior structure of excellent quartz stone are all dense and uniform, so it has low absorption and high penetration resistance; while the bad imitative quartz with a loose and porous interior structure has low penetration resistance and high absorption, which will appear in the using process in daily life.

③Green Guard is an authoritative and unprofitable supervision institution in the world environmental protection certification project. It strictly set standard about the indoor gas emission. Nowadays there are harmful plate products with exceeding formaldehyde doing harm to human health; therefore, it is no doubt that the enforcement of the standard is one of the best safeguards for users.

④Cost performance of useful life: quartz countertop with excellent quality will not faded with time, having a long service life and strong aging resistance, and don't worry about the troubles and inconvenience that table scratches and repeatedly repair and replacement of new face bring about. Its material value, service value, environmental health, convenience of use and aesthetics all have high added value. The prices of imitations are slightly lower, but their colors change quickly due to the oxidation in the process of using, and processing, installation process itself is not professional, so both in appearance and service life will be discounted.

⑤Professionalism of material:  Currently in the market some small-scale countertop processors pass the quartz synthesis applied to the floor or walls as the quartz stone in kitchen countertop, cheating consumers by means of the sham as the genuine to gain illegal profit. It should be noted that the two varieties are similar in appearance, but the cost of raw materials, the plate production process, and usage are completely different, so the choice of the quartz brand becomes really crucial.
