Quickly identify the authenticity of quartz stone

One: soak test with hydrochloric acid or the like. In order to maximize profits, some quartz stone manufacturers will add calcium carbonate in the production of quartz stone raw materials. The calcium carbonate capacity reacts with the acid. If such a countertop is purchased, the countertop is easily changed in the later use. Therefore, when purchasing, you can take a sample and put it in dilute hydrochloric acid or other acidic liquid to soak. If the product contains calcium carbonate, it will react with the acid and appear bubbles.

Second: test the staining. The surface and internal structure of high-quality quartz stone plate are also fine and uniform, with low water absorption and strong resistance to permeation; while inferior quartz stone is often limited to the appearance of similar, but the internal structure is loose and porous, weak in penetration resistance, and water absorption. Strong in soiling. When purchasing, you can pour the soy sauce on the quartz stone plate to see if it will bleed. The inferior quartz stone countertop will bleed for 1 day, but the quality will not.

Three: Check the wear resistance with a knife. The main component of quartz stone plate is silica, which has high hardness. The quartz stone on the market generally has a quartz content of more than 90%. Therefore, the possibility of occurrence of breakage is very small and relatively wear-resistant. Inferior quartz stone quartz sand is of poor quality, high impurity content, low surface hardness, and easy to scratch. When purchasing, you can try to draw a stroke on the board with a knife or the like.

Four: Check the heat resistance with fire. The quality of the resin used in inferior quartz stone is poor, the content is high, and the heat resistance is also reduced. Therefore, you can use this, burn a sample with a lighter, etc., and then see if there are burn marks left on it.
