At first glance, take the tableware to the place where there is a light source to see the refracted light on the surface. If the pattern part is the same as the part of the refracted light, it means that it is inferior, and vice versa. At the same time, it is necessary to check whether the shape of the device is regular and the surface has obvious defects; stacking several tableware of the same size and size, if the distance is not uniform, it means that it is inferior.
Second touch, touch the part with the pattern and no pattern by hand. If the two places are as smooth, it means that it is inferior; if there is a pattern part that feels obviously squeaky, the pattern is like a good item on the surface of the tableware.
Three scraping, the outer layer of the tableware is very hard, even if it is scraped hard, it will not damage the glaze. If the glazed pattern of the tableware can be easily scraped off, it is definitely inferior.
