Patent number: 3953623Abstract: Disclosed is a method of selectively coating a surface of a porous earthenware article. The article is heated only on the surface to be coated to which is applied powdered coating material. The coated article is post heated above the melting of the coating material but below the pre-heating temperature in order to produce a smooth coating. By heating below the preheating temperature, bubbles are prevented which may have accured because of the porous nature of the earthenware article. Also disclosed is a suction means for preventing coating material from being applied to undesirable portions of the article.Type: GrantFiled: May 28, 1974Date of Patent: April 27, 1976Inventor: Johannes Cornelis Das
