The so-called safety of ceramic coffee mugs mainly refers to the dissolution of lead and cadmium. Generally speaking, in order to make the surface of the ceramic mug look good, the surface is usually decorated with colorful patterns. Lead and cadmium are mainly introduced in these colors.
Liling Saida ceramic coffee cups are strictly tested, and their lead and cadmium dissolution is in line with national mandatory standards, so they are safe and reliable.The main bai components of the glaze are du silicon, aluminum, potassium, sodium, calcium, magnesium, and iron. The lowest firing temperature is also above 1000 degrees Celsius，The dissolution of lead and cadmium is lower than the requirement of GB12651-2003 “Allowable limit of lead and cadmium dissolution of ceramic products in contact with food”.
Also, there is a misunderstanding here. Some people may have seen that there are some heavy metal salts in ceramic glaze or color materials, which are considered toxic. In fact, heavy metals are not used in daily ceramics! It is the heavy metal salt. Through high temperature reaction, the form is very stable, and it is impossible to dissolve during use. You can see the method to detect the dissolution of lead and cadmium, which is to soak in 4% glacial acetic acid for 24 hours, and then use atomic absorption. Measured by the instrument, the dissolution volume cannot exceed 7 parts per million of the liquid volume. Who would use porcelain like this? So this toxic is basically a false proposition.
Ceramic products such as ceramic cups and ceramic tableware used in our lives are fired in a furnace with a temperature of over 1280 degrees, which is completely non-absorbent and resistant to high temperature and corrosion. If it is poisonous, what kind of poison can withstand the test of 1280 degrees? Another thing in our daily life is that there are no high-temperature objects poured into a ceramic cup or bowl. The maximum is 100 degrees of boiling water and 23 Baidu hot oil. Compared with ceramic cups and bowls, it is really easy.
The first choice for coffee mugs should be ceramic coffee mugs. Among cups of all materials, ceramic mugs are the healthiest.
