Li2CO3 is the chemical formula for lithium carbonate, which is a white salt used in the production of lithium-ion batteries, ceramic glazes, and psychiatric medications.

CdCO3 is the chemical formula for cadmium carbonate. It is a white, powdery compound used in pigments, ceramic glazes, and as a precursor for cadmium oxide production. Cadmium carbonate is toxic and exposure should be avoided.

Ceramic grade sand is less than 75mm and has a silica content above 97.5%, impurities include <0.55% Al2O3 and <0.2 Fe2O3. It is used in the production of glazes and ceramic materials. http://www.azom.com/details.asp?ArticleID=1114
Ceramic mugs are generally safe. Some glazes used in ceramics can leach metals into liquids used in them: responsible makers test the glazes used on items intended for food use before selling them. It is possible for porous ceramics to harbor bacteria, especially if the glaze is cracked or crazed, but there is little risk if the item is washed before use, and is not used for storage.
There can be. Some pottery (and some glazes) use lead and that can be hazardous.
Lead is used as a coloring element in ceramic glazes, notably in the colors red and yellow. It USED TO be used in pencils but now they are made with graphite.
Chromic acid is used in ceramic glazes and colored glass and it can also be mixed with sulfuric acid and used as an oxidizing agent to clean glassware in labs.
Chase Brown is an artist that uses glaze. The art that he creates is ceramic, he glazes and uses fire to heat his ceramics, this makes every one unique.
Barium carbonate (BaCO3) is a chemical compound composed of one barium atom, one carbon atom, and three oxygen atoms. It is commonly used in the manufacturing of ceramic glazes, cement, and other barium compounds.
Fired properties of glaze include its appearance, texture, adhesion, and durability. Upon firing, glazes can develop various finishes, such as glossy, matte, or satin, affecting the aesthetic of the ceramic piece. The glaze must adhere well to the clay body to prevent flaking or chipping, and it should be durable enough to withstand daily use, including resistance to moisture and thermal shock. Additionally, fired glazes can exhibit variations in color and opacity, influenced by their chemical composition and firing temperature.
