Ceramic does not leach chemicals into food like plastics can.
Ceramic is non porous and is not permeable to water, air or other fluids.
Ceramic is also non toxic and made of natural materials including minerals and clay does not contain added chemicals or plastic or vinyl.
The ceramic material is safe for both food and drinks and is even safer than stainless steel.
Stainless steel can possibly leak metals such as chromium and nickel into food but ceramic cannot leach any of those into food or drinks as ceramic does not contain any of those chemicals.
Ceramic cookware is also safe to use if it is properly glazed, using materials authorized for food contact use, and the glazing is intact,”.
Stoneware and porcelain are also considered to be the best for food safe types of clay, as they are fired at high temperatures that make them less porous and less likely to leach chemicals.
Earthenware is more porous and is more likely to leach chemicals.
