Ceramics, the product of an encounter between clay and fire. After being sifted, crushed and mixed, shaped and calcined, the natural clay is fired at different temperatures to produce different ceramics. There are many different types of porcelain, and different types are used in different ways. For example, do you really know anything about the ceramic tableware that we most often come into contact with?
First of all, let’s talk about what a glaze is. It is a thin glassy layer that covers the surface of ceramics to prevent contamination of the ceramic body, to increase the strength of the surface and to prevent corrosion. When we touch the surface of a ceramic and it feels smooth, we are touching the glaze. Most of the time we are not in contact with the ceramic body, are dealing with the glaze, so the safety of the glaze also becomes the most important consideration. Generally speaking, the glaze of ceramics is non-toxic to the human body. It is made of feldspar, quartz, talc, kaolin, etc., which are mixed and ground into a slurry in a certain proportion and evenly covered on the surface of the body before the ceramics are fired, and then fired together.
Ceramic tableware is usually used in the process, the main lightly, otherwise it is easy to break or cause gaps. Broken ceramic tableware is best taken out separately and put aside, not only because its broken mouth is easy to scratch other tableware, and the gap is also easy to spill glaze, if it is with the food into the body, the harm cannot be ignored. And usually when cleaning ceramic can first scald with hot water, so that you can dissolve the oil stains on top of the tableware, and then wash with water afterwards, no longer greasy feeling.
Ceramic tableware is not only beautiful, but more importantly, it is in direct contact with the human body, so we require its inherent quality and safety to be good.
