(1). Production process
The production process of ceramic cups includes multiple steps such as material selection, molding, drying, firing and glazing. First, select high-quality pottery clay or porcelain clay, mold it through a mold, and then dry and fire it at high temperature. Finally, glaze it as needed to give it a beautiful appearance and good waterproof performance.
(2). Material composition
• Glaze: Glaze is a protective layer on the surface of ceramic cups, and its main components include silicates, aluminates, etc. After being fired at high temperature, the glaze forms a glass texture, which has waterproof, anti-fouling and beautifying effects.
(1).Hazards of lead and cadmium
During the production of ceramic cups, some inferior glazes may contain heavy metals such as lead and cadmium. Lead and cadmium are harmful to human health. Long-term intake may cause poisoning and affect the health of the nervous system, kidneys and bones.
(2). Harm of inferior glazes
1. Try to choose products from well-known brands and regular channels. These brands usually have strict quality control to ensure that the products meet national and international standards and reduce the risk of harmful substances.
2. Check the product logo When buying a ceramic water cup, pay attention to the product logo and instructions. Regular products usually indicate the material, manufacturer, implementation standards and other information.
3. Choose lead-free and cadmium-free glaze Modern ceramic technology has been able to produce lead-free and cadmium-free environmentally friendly glazes. When purchasing, you can choose products marked "lead-free and cadmium-free" or "environmentally friendly glaze" to reduce the risk of heavy metals.

(1). Treatment before first use Before using a newly purchased ceramic cup for the first time, it is recommended to wash it thoroughly with clean water and boil it in boiling water for a few minutes to remove any harmful substances and odors that may remain.
(2). Avoid long-term storage of acidic or alkaline liquids Acidic or alkaline liquids (such as juice, carbonated drinks, etc.) may accelerate the migration of harmful substances in the glaze. It is recommended to avoid using ceramic cups to hold these liquids for a long time.
(3). Avoid drastic temperature differences Ceramic cups are sensitive to temperature changes, and drastic temperature differences may cause the cup body to crack or the glaze to fall off. When using, avoid placing the ceramic cup directly from a cold environment to a high temperature environment, or vice versa.
(4). Regular inspection and replacement After using it for a period of time, regularly check whether the glaze layer of the ceramic cup is intact. If the glaze layer is found to be cracked or falling off, it is recommended to replace it in time to avoid the migration of harmful substances.
