Abstract

PROBLEM TO BE SOLVED: To provide a glazing jog which allows glazing without the remaining of the traces of fingers at a foot and the adhesion of the stripes of the glaze falling from the fingers near to the foot. SOLUTION: The glazing jig 10 comprises a doughnut-shaped plate 12 made of a synthetic resin, such as polyvinyl chloride, and is provided with a circular through- hole 14 having the diameter size smaller than the diameter size of the foot 22 of a green ware body 20 at its central part and a flat supporting surface 28 with which the foot 22 is brought into approximately tight contact between the outer peripheral marginal part 16 of the doughnut-shaped plate 12 and this through-hole 14. If the jig is formed in such a manner, the supporting surface 18 of the glazing jig 10 is wetted with the glaze 24 and the foot 22 is brought into contact therewith in this state, by which the moisture absorption of the glaze 24 by the foot 22 is induced and the green ware body 20 is held. The green ware body 20 is immersed into a glaze slurry in this state, by which even a beginner is enabled to easily glaze the foot 22, etc., without leaving the traces of the fingers. Since the outer peripheral marginal part 16 of the glazing jig 10 projects outer than the foot 22, the fall of the glaze 24 to the green ware body 20 from the glazing jig 10 and the adhesion of the stripes, etc., are suppressed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glazing jig used for immersing a ceramic body in glazing slurry for glazing.

[0002]

2. Description of the Related Art As a means for glazing a ceramic body, there is a method in which the body is gripped by hand and immersed in glaze slurry. In the case of a ceramic having a ring-shaped beach (projection) at the bottom, for example, as shown in FIG.
Usually, it is held by 4 and immersed in the glaze slurry.

[0003]

However, in such a conventional glazing method, the quality is impaired due to a trace of a finger remaining on the beach or a streak of glaze flowing down from the finger near the beach. There was fear. In particular, in the case of ceramics such as inner iron products such as cups and teacups and single-molded products which are tall and have a small diameter of the beach portion, the beach portion is difficult to grasp, and thus the above problem becomes remarkable.

[0004] The present invention has been made in view of the above circumstances, and its purpose is to leave traces of fingers on the beach or to have streaks of glaze flowing down from the fingers near the beach. It is an object of the present invention to provide a glazing jig that can be glazed without any problem.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a glazing treatment which is used when a ceramic body having an annular beach at the bottom is immersed in a glaze and glazed. A through hole smaller than the beach is formed, and the outer peripheral edge is located outside the beach in a state where the through hole is located inside the beach; Is mainly composed of a plate-like member having a flat support surface which is substantially adhered, and the base is held by being brought into close contact with the beach portion in a state where the support surface is wet with glaze. .

[0006]

According to such a glaze jig, the beach is brought into close contact with the support surface being wet with the glaze, so that the water of the glaze is absorbed by the beach and the ceramic body is held. Therefore, by immersing the base material in the glaze slurry in this state, even beginners can easily apply glaze without leaving finger marks on the beach etc., and the outer edge of the glaze jig protrudes outside the beach As a result, the glaze is prevented from flowing down from the glazing jig onto the ceramic body and forming streaks. Further, since no finger mark remains, only an extremely narrow range at the tip of the beach can be set as an unglazed area, and the quality is further improved. The glaze is also satisfactorily applied to the inner peripheral portion of the beach due to the presence of the through hole.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The glaze jig of the present invention is suitably used for glazing a ceramic body having a tall and small diameter of a beach, such as an inner iron product or a single molded product. Of course, it can also be used for glazing of ceramics with a relatively large diameter at the beach, such as outer iron products.

The plate-like member is formed of, for example, a donut-like plate made of a synthetic resin such as vinyl chloride having a thickness of about 10 mm, and the outer peripheral shape of the plate-like member and the shape of the through hole are not necessarily circular. No need to be. The size of the through hole is
It is desirable that the size be slightly smaller than the diameter of the beach so that the glaze can easily enter, and it is desirable to prepare a plurality of types in accordance with the diameter of the beach of the ceramic to be applied. However, it is a matter of course that the same glazing jig may be used for glazing a plurality of types of ceramics having a relatively small diameter of the beach portion. By setting, it is also possible to use a single glazing jig for all types of ceramic glazing.

By providing a handle portion integrally with the plate-like member, or by providing a handle member on the back surface of the plate-like member, that is, on the surface opposite to the support surface, the operator does not need to put his hand in the glaze slurry. It is possible to perform glaze work. Of course, the glaze work can be automatically performed by moving the glaze jig with a robot or the like.

An embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view of a glaze jig 10 to which the present invention is applied, FIG. 2 is a view showing an example of use of the glaze jig 10,
3 is a sectional view taken along line AA of FIG. 2, and FIG. 4 is an enlarged view of a part of FIG. In FIG. 1, a glazing jig 10 is composed of a doughnut-shaped plate 12 made of a synthetic resin such as vinyl chloride having a thickness of about 10 mm and a base 20 described later in the center (see FIGS. 2 and 3). A flat support having a circular through hole 14 having a diameter slightly smaller than that of the beach portion 22, and the beach portion 22 being substantially in close contact between the outer peripheral edge portion 16 of the donut plate 12 and the through hole 14. It has a surface 18. The donut-shaped plate 12 corresponds to the plate-like member.

As shown in FIGS. 2 and 3, the base 20 is made of a ceramic material such as a tall and small-diameter cup, and has a cylindrical hollow container 21 having a bottom and a protrusion protruding from the bottom of the hollow container 21. And an annular beach 22 provided. The glazing jig 10 has the support surface 18 wet with the glaze 24 while the through hole 14 is located inside the beach 22 and the outer peripheral edge 16 is located outside the beach 22. By being brought into close contact with the portion 22, the water of the glaze 24 is absorbed by the beach portion 22, and the substrate 20 is held. Glazing jig 10
The substrate 20 held by the above is glazed by holding the glazing jig 10 and immersing it in the glaze slurry.

As shown in FIG. 4, the beach 2
2 has a semi-circular cross section at the tip, the contact area of the glaze jig 10 with respect to the support surface 18 is extremely small, and there is no finger mark. It is limited to a narrow range, and the range (width dimension) in which glaze 24 is removed to eliminate surface irregularities after glaze can be reduced.

As described above, according to this embodiment, the support surface 18 of the glazing jig 10 is brought into close contact with the beach 22 in a state of being wet with the glaze 24, so that the water of the glaze 24 is absorbed by the beach 22. By holding the ceramic body 20 and immersing the body 20 in the glaze slurry in this state, even a beginner can easily perform glaze without leaving a finger mark on the beach 22 or the like. Since the part 16 protrudes outward from the beach part 22, the glaze jig 10 is
The glaze 24 is prevented from flowing down and forming streaks or the like. Also, since no finger marks remain, only the very narrow area at the tip of the beach 22 can be set as the area where the glaze 24 is not applied.
The quality is further improved. Note that the presence of the through-holes 14 also allows the inner peripheral portion of the beach portion 22 to be satisfactorily glazed.

The present invention can be modified in various other ways without departing from the gist thereof.
