What is meant by unglazed?
Most earthenware and natural clay cooking utensils are coated with a glaze. This is a shiny coating applied to the surface to provide decoration and to seal the piece making it less susceptible to stains. But commercial glazes often contain pigments or chemical impurities that do touch the food. Other non-stick coatings, such as Teflon , have been found to contain trace amounts of the chemicals use in their manufacture. Many are concerned about the long-term effects of these substances on humans. Traditional hard-fired unglazed clay, like the VitaClay pot, have no such coatings. Unglazed clay has been used for thousands of years all over the world as cooking vessels. The slightly porous natural clay enables additional steaming not possible in metal, glass, or glazed ceramic pots. The VitaClay line of slow cookers brings the healthy benefits of this ancient cooking to the modern kitchen with 21st century features.
