  In the case of a pot for cooking cooked pottery, it is required to decorate the inner surface on which the convex portion is formed by changing the color of the convex portion, the pattern on the inner surface, the pattern, etc. The formation of convex portions by pressing has a drawback that the inner surface cannot be decorated by changing the color, pattern, pattern, etc. of the convex portions.

  Moreover, in the said patent document 1, since the press machine provided with the upper mold | type was used for forming a convex part, whenever the shape of a convex part, a magnitude | size, height, or the space | interval between convex parts changes, There is a problem that it is not possible to easily adapt to the design change because the upper mold must be prepared and replaced for each.

  Accordingly, the present invention provides a ceramic cooking device for cooking and cooking, which is capable of decorating the embossed surface on which food is piled up, and can easily cope with a change in the design of the embossed surface. A method is provided.

  The method for manufacturing a ceramic device for cooking according to the present invention comprises a method of forming a plurality of convex portions colored with a predetermined height and interval on a surface on which a food material of a ceramic device is placed by a transfer paper on which a paint is printed in multiple layers. It is characterized by firing after being transferred into a shape. Moreover, you may form a pattern by the colored convex part.

  The ceramic cooking device for cooking according to the present invention is such that a plurality of convex portions are arranged in a mesh shape by transfer with a transfer paper in which paints are printed in multiple layers at predetermined heights and intervals on the inner surface of the ceramic cooking device. Features. Moreover, you may form a pattern by the colored convex part.

  The ceramic is selected from known ceramics containing one or more components such as aluminum oxide, silicon oxide, iron oxide, magnesium oxide, calcium oxide, titanium oxide, zirconium oxide, silicon carbide, and silicon nitride.

  The shape and size of the ceramic vessel is appropriately designed according to the type and size of food such as meat, fish and vegetables to be cooked, and the type of heating method such as a microwave oven, oven and gas stove. It is preferable that the vessel has a shape in which fat, juice, and the like coming out of the food by heating do not spill out of the vessel, for example, a concave cross section, or a groove is formed around the vessel.

  The convex portion formed on the inner surface of the vessel on which the food is placed is appropriately selected from a triangular shape, a quadrangular shape, a polygonal shape, a circular shape, an elliptical shape, or the like. As for a convex part, it is desirable that a diameter is 1.5-2.0 mm, height is 0.3-0.5 mm, and a space | interval is 1.0-1.5 mm.

  The transfer paper used to form the projections is the same as the transfer paper for ceramics that is usually used, and the water-soluble glue applied to the surface of the mount and the pigment by repeating screen printing several times on the top of the glue. A paste-like paint kneaded with oil and frit is rubbed with a squeegee to thickly print an ink-like paint paint and a cover coat layer of synthetic resin such as acrylic covering the top of the dried paint paint Do it.

As the color substrate that is the main component of the paint, oxides such as ZnO, Fe ₂ O ₃ , CoO, Al ₂ O ₃ , Cr ₂ O ₃ , and solid solutions of these oxalates are mainly used. A borosilicate glass mainly composed of B ₂ O ₃ , SiO ₂ , and PbO is used.

  The pattern can be transferred in various shapes and colors. For example, various shapes and colors such as a shape of an animal, a picture of a plant such as a flower, and a picture of a fish are possible.

  When the transfer paper is immersed in water, the water-soluble paste dissolves and the acrylic is peeled off from the mount. Since the acrylic paint that has been printed on is attached to this acrylic, if the acrylic paint layer is attached to the inner surface of the ceramic and baked, the acrylic will evaporate and burn, and the painted paint will be baked on the inner surface of the ceramic. After being transferred, a plurality of convex portions are formed.

  The pattern printed on the transfer paper forms a convex portion and a pattern having a clear color tone.

  In the present invention, a convex portion can be formed by transfer on an embossed surface on which food is placed, and coloring is also possible, and further, it can be decorated with a pattern. Therefore, when the design of the embossed surface is changed, it is possible to easily cope with the change of the design of the transfer paper by screen printing. As a result, it becomes possible to manufacture ceramic devices having various designs.

  In the present invention, the convex portions can be formed by a large number of transfer papers having a constant pattern by screen printing, so that the convex portions can have a constant dimension, and as a result, a constant ceramic device can be produced. Dimension is stable and product accuracy is stable.

  The present invention has a step (gap) lower than the convex portion between the convex portion and the convex portion by forming the convex portion. Easy to burn, easy to peel off.

(A) is a perspective view which shows an example of the ceramic-made container of this invention, (b) is a fragmentary sectional view of (a). It is a top view which shows the Example which formed the pattern in the ceramics container of this invention.

  Embodiments of the present invention will be described with reference to the drawings.

  In this example, a large number of white protrusions are formed on the inner surface of a black ceramic container. The background may be left between the convex portions without coloring the ceramic.

  In FIG. 1, on a water-soluble glue layer applied to a mount, paste-like paint prepared by kneading a white pigment and frit with oil was rubbed with a squeegee and lined up at regular intervals vertically and horizontally by screen printing. Print a large number of dots. Dots are printed in layers, and the height is adjusted according to the printing thickness. After drying the paint, a synthetic resin cover coat layer is laminated on the upper surface of the paint. The convex portions have a diameter of about 2 mm, a height of about 0.3 mm, and a spacing between the convex portions of about 1 mm.

  The transfer paper thus obtained is immersed in water to dissolve the water-soluble glue, and the cover coat layer with the paint is peeled off from the mount.

  The paint layer is attached to the inner surface of the ceramic device 1, fired at 800 ° C. to 820 ° C., the cover coat layer is evaporated and burned, the paint is baked and transferred, and a plurality of convex portions 2 are formed.

  Although the fish was placed on the ceramic container of this example and baked on a gas stove, it was hardly burnt. Also, the burnt portion could be easily removed.

  In the present embodiment, as shown in FIG. 2, a large number of convex portions 2 are formed on the inner surface of the ceramic device 1 and a pattern 4 is formed. Grooves 3 are formed in the surroundings so that fat, juice, etc. from the ingredients do not spill out of the vessel.

  When the pattern 4 is colored on the convex part 2, a color plate is formed on the convex part 2 forming the pattern 4 in the same manner as the convex part 2 forming the whole, and the number of color plates is superimposed on the convex part. The pattern is formed by.

  For example, when the pattern has seven colors such as red, blue, yellow, and green, the convex portions are formed with seven colors according to the color of the pattern, so seven plates are made for each color, and seven plates are printed one by one. By doing so, the pattern 4 is formed simultaneously with the whole convex part 2.

  As another forming method, after the transfer paper with the pattern 4 is baked on the ceramic container 1, the convex portion 2 of the same color as in Example 1 or the convex portion colored by the same process as the above-described step by the transfer paper 2 can also be formed.

  By decorating ceramics with a pattern, it was possible to create a good-looking vessel.
