Ceramic cup classification introduction and benefits

Cup products, as food contact containers that are used frequently in daily life, are commercially available in different materials for consumers to choose from; different materials reflect different product characteristics. Common cup products are mostly made of ceramics.

Pottery and porcelain are actually two different things, although we are accustomed to associate them together; pottery has a higher water absorption rate than porcelain; the texture of pottery is relatively loose and softer than porcelain; pottery and porcelain formed at high temperatures Cups, bad substances and impurities in the soil embryo no longer exist at high temperatures. The formed cups are thick, smooth and clean.

Ceramic materials are roughly divided into 4 categories:

Bone china:

The basic process is a kind of porcelain that uses animal bone charcoal, clay, feldspar and quartz as basic raw materials and is fired twice through high-temperature biscuit firing and low-temperature glaze firing. The two basic characteristics of bone china are the essential basis for distinguishing bone china from other porcelain. Feature 1: The bone char content is 36% or above (national standard); Feature 2: It is made through secondary firing (bisque firing, glaze firing).

According to the bone china standards set by the United Kingdom, it contains 30% tricalcium phosphate from animal bones, and the finished product is translucent, so it can be called bone china. The American standard is at least set at 25%.

porcelain:

Adding fire to the pottery-making temperature will turn pottery into porcelain. The difference between pottery and porcelain lies in the difference in raw material soil and temperature. Pottery is fired at a temperature of 800-1000 degrees, while porcelain is made of kaolin fired at a temperature of 1300-1400 degrees.

There is also a kind of jade porcelain, which is made from mineral rocks and carefully developed through modern nanotechnology. It has a delicate and white texture, jade-like skin, high purity and smoothness, extraordinary transparency and gloss, and extraordinary look and feel. Different from traditional ceramics, in a general sense, jade porcelain refers to mineral porcelain, also known as mineral powder porcelain.

enamel:

Many friends must have felt nostalgic after seeing this product. In fact, enamel is an inorganic glass enamel painted on the surface of a metal base. Enamel coating on the metal surface can prevent the metal from rusting, prevent the metal from forming an oxide layer on the surface when heated, and prevent the metal from being corroded by various liquids.

Enamel products are not only safe and non-toxic, easy to wash and clean, but also combine the strength of metal with the gorgeous appearance of enamel and resistance to chemical corrosion. It can be widely used as eating utensils and washing utensils used in daily life, and under certain conditions, the enamel coating on the metal body shows excellent properties such as high hardness, high temperature resistance, wear resistance and insulation, making it Enamel products have a wider range of uses.

ceramics:

Ceramics are made of clay as the main raw material and various natural minerals

Materials and various products obtained by crushing, kneading, shaping and calcining.

People call items made of clay and fired at high temperatures in special kilns called ceramics. The main raw materials for them are silicate minerals (such as clay, quartz, etc.) obtained from nature. Ceramics is the general term for pottery and porcelain. The traditional concept of ceramics refers to all artificial industrial products using inorganic non-metallic minerals such as clay as raw materials.

Ceramic cups have the following benefits:

(1) Thick and feels, relatively stable

One of the characteristics of melamine is that it is relatively light, while stainless steel is slightly heavier. However, due to material problems, the cup is relatively slippery.

(2) Smooth surface and easy to clean

Melamine is prone to deformation and discoloration when used and maintained improperly. After the surface is worn, it is easy to color and difficult to clean; stainless steel is also easy to color and difficult to clean tea stains.

(3) safer

Ceramics do not release harmful substances when high temperatures occur; it has no effect on food or water itself, making it safer to use.

(4) Better thermal insulation performance

Melamine is generally not recommended for containing high-temperature foods or drinks such as water. Stainless steel is relatively safer in terms of safety, but ordinary cups (notcup and kitchen) It is easy to cool down after filling hot drinks; the heat preservation performance of ceramic cups is superior, and if it is a bone china cup, the heat preservation performance is better.
