Abstract
A moisture control construction material is enhanced in decorativeness and improved in stain-resistance by glazing the surfaces thereof. The material is prepared by mixing soil material and clay, molding the mixture to a body, applying glate on the body and firing the body. The body may be performed biscuit firing before glazing. The moisture-absorbing-and-desorbing-performance thereof in each 8-hour cycle is more than 80 g/m2. The body has prosity of 20-25%. More than 40% of pores of the body have a radius of less than 0.1 μm.
