PURPOSE:To prevent the temporal loss of the matte state of a matte glass bottle havng minute protrusions on the surface, caused by the sweat and grease of fingers, etc., by making the height of each protrusion high, and the areal density of the protrusions low. CONSTITUTION:A matte surface 3 is formed by forming minute protrusions 2 on the surface of a glass bottle 1 by the corrosion process with an agent such as hydrofluoric acid, ammonium fluoride, etc., or sand-blasting, glassbead-blasting, etc. In the above process, the height of each protrusion is made high, and the areal density of the protrusions is made low, e.g. by carrying out the matte processing under the condition to increase the etching roughness. The volume of the groove between the protrusions is made by this process to a level to prevent the plane connection of the tips of the protrusions 2 with sweat, etc. even if the sweat, etc. of finger, etc. is attached to the groove. The matte surface 3 is printed with a lustering paint 5, etc. to obtain the objective glass bottle.
