GLASS PRODUCT DECORATED WITH JAPANESE LACQUER

PROBLEM TO BE SOLVED: To obtain a glass product extremely rich in decorability, having an elegant decoration, free from the peeling of a decorated part containing a Japanese lacquer, and thereby capable of being supplied for practical use as a general table ware by processing the surface of a glass ware into an opaque processed glass ware, drawing a desired pattern at the arbitrary site of the processed glass ware with a silane coating containing the Japanese lacquer with hands or forming a desired transparent pattern by a screen printing method. SOLUTION: This glass product decorated with a Japanese lacquer is obtained by blasting the surface of a glass ware with sand to form a fine uneven surface, or treating the surface of the glass ware with hydrogen fluoride to roughen the surface of the glass ware, and subsequently subjecting an arbitrary part of the formed opaque glass ware to a hand drawing treatment using a brush, etc., or a screen printing treatment using a silk screen type device under the use of a coating comprising 100 pts. of a red Japanese lacquer and 1-5 pts. of a silane coupling agent having a chemical structure (X is an inorganic group; R is an organic group).
