Abstract

PURPOSE:To completely remove the carbon which adheres to crystallized glass without affecting other parts by performing ultrasonic wave cleaning in the aqueous solution in which abrasive material and surface active agent are contained after sintering. CONSTITUTION:The crystallized glass 3 on which the carbon 4 adheres is contained in the surface active agent aqueous solution 5 in which the abrasive material 6 is contained and is ultrasonically cleaned. This cleaning permits the abrasive material 6 to oscillate by ultrasonic energy. The carbon 4 is separated from the surface of the crystallized glass 3 by this oscillation energy and is liberated in the surface active agent aqueous solution 5. The liberated carbon 4 is covered by the surface active agent and is prevented from re-adhering to the crystallized glass 3.
