PROBLEM TO BE SOLVED: To uniformly coat the both sides of an inequilateral corner tile with glaze by installing a movable rail vertically movable at a part in which a rail of a glaze position of a stationary rail is cut off in the length direction of the rail and a lifting and lowering apparatus for lifting and lowering the movable rail from the same height as that of the stationary rail ahead and behind the part toward its upper position. SOLUTION: In glazing a substrate (a) of an inequilateral corner tile, when a piston rod 17 of an air cylinder 16 is advanced, a movable rail 14 has a top position. When a rolling wheel 12 having traveled on a stationary rail 4 reaches the end of the rail, one side of a groove 13 of the rolling wheel 12 travels on an end part 14a of the movable rail 14 and the rolling wheel 12 reaches a horizontal part of the movable rail 14. Since the rolling wheel 12 is raised when passing on the movable rail 14 and a placing member 10 is inclined forward downward, the rolling wheel travels on a glazing position X while placing the substrate (a) of the inequilateral corner tile on the placing member 10 with laying its long side forward. Consequently both sides of the inequilateral corner tile is distributed at 45 degrees based on a horizontal plane and both the sides are uniformly glazed.
