PROBLEM TO BE SOLVED: To have both antibacterial and soilproof characteristics and to attain sustained effect and increased strength by forming photocatalyst layers consisting of transparent titanium oxide on surfaces of constitution members such as glass vessel, window glass, glass lid and top board consisting of ceramic raw material. SOLUTION: On an upper part surface of the glass vessel 1 consisting of ceramic raw material, very little pear-skin treated part 1a is formed by using blast processing, etc. The pear-skin treated part 1a is formed at least in a part of the place where the photocatalyst layer 1b is formed. The photocatalyst layer 1b consists of transparent titanium oxide and is formed on the whole surface of the glass vessel 1 including the pear-skin treated part 1a. The photocatalyst layer 1b is formed by dipping the glass vessel 1 in a treating liquid consisting essentially of a titanium isopropyl alkoxide, drying them, baking at 500 deg.C. In this mixer, both antibacterial and soilproof effects are obtained and, further, sustained effect and increased strength are obtained. |
