Give reason: Water kept in porcelain container will not get cooled if it is glazed.

Description : Give reason: Water kept in porcelain container will not get cooled if it is glazed.

Last Answer : Glazing plugs the pores present in porcelain articles. If pores are present, water oozes from these pores and gets evaporated. This has a cooling effect on the water inside, As the pores are plugged, water does not get evaporated hence no cooling.
