<p>PCT No. PCT/GB93/02132 Sec. 371 Date Aug. 2, 1995 Sec. 102(e) Date Aug. 2, 1995 PCT Filed Oct. 15, 1993 PCT Pub. No. WO94/08917 PCT Pub. Date Apr. 28, 1994A method of treating earthenware bodies to enhance resistance to freezing and to assist the application of decals and the like thereto comprises treating the bodies with a liquid medium containing a water-repellent material such as silicone. In a subsequent drying step, the bulk of the liquid medium is removed while leaving the water-repellent material deposited in the pores of the earthenware body. In this way, subsequent entry of water and freezing and cracking is resisted. It has also been discovered that the treatment also enchances the ability of the earthenware surface to receive decals and the like without the need for glazing and an additional firing step.</p> |
