The palayok is made of earthenware, a porous ceramic material. This allows steam from cooking to evaporate out of the pores in the earthenware. Juices from the cooking food would not begin to burn until all the water has evaporated, after which the food is thoroughly cooked. Since ceramic does not transfer heat as much as metal, cooking in a palayok entails a longer time and a higher temperature that would normally be using metal cookware.[1]
