Description

  The present invention relates to a ceramic tableware having a lacquer surface on the surface or inner surface that comes into contact with food.

  In ceramics, containers whose surface is formed into a lacquer surface are known. Specifically, in Patent Document 1 (Japanese Patent Application Laid-Open No. 2000-139661), there is a ceramic ware having a lacquered lacquer, which is obtained by repeatedly thinning raw lacquer with turpentine oil on the surface of an unglazed ceramic ware and applying and drying it several times. It is disclosed.

  Moreover, in patent document 2 (Unexamined-Japanese-Patent No. 2002-355155), in a lacquer ware, as a means to negatively ionize food and drink when using a lacquer ware, a fine powder of tourmaline is kneaded and applied to a lacquer paint. Is disclosed.

JP 2000-139661 A. JP 2002-355155 A.

  In order to express the luster of the lacquer ware on the surface of the ceramic, when it is simply formed by applying and drying lacquer on the ceramic body, there is a problem with adhesion, unlike the wooden material of lacquer ware, it is easy to peel off and durable There is a problem.

  Further, simply mixing fine powders of useful minerals to enjoy the negative ion effect has a problem with the enjoyability, and it cannot be said that the aesthetic effect of the lacquer ware is excellent.

  Accordingly, the present invention proposes a new ceramic tableware that can further enjoy the effects of useful minerals such as the negative ion effect, in addition to the further aesthetic effects of lacquerware in ceramic tableware.

  The ceramic tableware according to the present invention is a base layer portion formed by applying and baking lacquer on the unglazed surface of a ceramic tableware body fired by applying a desired glaze to the other surface with the food contact surface unglazed. And on the surface side of the base layer portion, a smooth surface and a granular useful mineral that can be visually recognized are mixed in the lacquer layer, and an upper layer portion in which a part of the useful mineral is exposed on the surface is provided. It is characterized by.

  Thus, in the ceramic tableware, the inner surface is formed on a lacquer ware surface if it is a container, and the upper surface is formed on a lacquer ware surface if it is a dish. Since the upper layer part which is a lacquer layer is laminated and adhered firmly on the lacquer surface (base layer part), the lacquer ware layer part is firmly integrated. In addition, the surface of the lacquer ware exhibits a unique decoration effect due to the pattern (the action as an absorption polarizer, the reflected light of the mineral and the minute uneven surface) of the exposed surface of the useful mineral (particles).

  Further, in the ceramic tableware according to the present invention (Claim 2), the useful mineral (particles) of the upper layer part may be all or several kinds of grains selected from tourmaline, columbite, feldspar, xenotime, black silica, vital atom. It consists of a mixture of the body, the useful mineral has a pyroelectric effect depending on the temperature, a weak current flows due to humidity (moisture contact), negative ions are released, and the food contained in the tableware is purified, Moreover, the diversity of patterns by the difference in the material of a granule is obtained.

  Further, the ceramic tableware according to the present invention (Claim 3) is obtained by further mixing fine powder of charcoal in the upper layer portion, and the fine mineral powder intervenes between the particles of the useful mineral, so that the useful mineral The unevenness of the surface of the useful mineral adhesion layer is made shallow and the formation of a smooth surface is facilitated by filling the space between the particles of useful minerals with fine coal powder without uneven distribution of the particles. .

  The present invention is as described above, and in ceramic tableware, it has sufficient durability, has an aesthetic effect due to a lacquer surface with a pattern in which particles of various useful minerals are scattered, and further, with useful minerals, The tableware which can also enjoy the desired effect (pattern diversity, a negative ion effect, antibacterial purification action) was able to be provided.

  Next, an embodiment of the present invention will be described. The tableware shown in the embodiment is formed by laminating a base layer portion 2 and an upper layer portion 3 formed of lacquer as a main material on a predetermined surface (unglazed surface) of a tableware body 1.

  The tableware body 1 forms an unglazed body (pottery or porcelain) 11 having a desired tableware shape in a container shape or a dish shape. In this unglazed body 11, the inner surface is a container and the upper surface is a dish. A surface other than the abutment surface is hung and subjected to main baking, and if necessary, painting (with a lower picture, with an upper picture) is provided, and a surface portion (hanging portion) 13 having a desired wrinkle pattern 12 is provided. It is a thing.

  The base layer 2 is coated with a slightly thin raw lacquer on the unglazed surface of the tableware body 1 (non-glazed application surface in the unglazed body 11), and the lacquer solution is infiltrated into the fine holes of the unglazed surface and baked (about 200 ° C.). And then polished with paper to form a moderately smooth surface (including slight irregularities and fluffing).

  The upper layer portion 3 is formed by layering an undercoat layer 31, a mixed layer 32, and a finishing layer 33. The undercoat layer 31 is coated with a thin black lacquer (other color lacquer may be used) and dried. Smoothing (paper polishing) is performed.

  The mixed layer 32 is applied with a slightly thick black lacquer (other color lacquer may be used) on the upper surface of the undercoat layer 31 to form an adhesion layer 321, and tourmaline, columbite, feldspar, xenotime, black silica, vital atom, all Alternatively, particles (useful minerals) 322 mixed by selecting several types and fine charcoal powder (Bincho charcoal, bamboo charcoal, etc.) 323 are mixed and dispersed and adhered to the adhesion layer 321.

  Moreover, it replaces with the said means, the granule 322 and the charcoal fine powder 323 may be mixed with the lacquer liquid, and this mixed lacquer liquid may be applied to adhere the granule 323 and the charcoal fine powder 323 of useful minerals. .

  Furthermore, the surface of the mixed layer 32 becomes an uneven surface due to the adhesion of the granules 322, but the lacquer is applied to make the adhesion of the deposits (particles 322 and fine carbon powder 323) robust, and after drying, polishing is performed. By repeating this several times, lacquer, granules 322, and fine carbon powder 323 are integrated, and the polished surface of the granules 322 is exposed.

  The finishing layer 33 is applied with fresh lacquer (black lacquer or colored lacquer), dried, polished after drying, further coated with fresh lacquer, oil-dried after drying, and further applied with oil-grown and polished powder of fresh lacquer. Glossy by polishing.

  Therefore, in ceramics with a glaze finish on the outside, the lacquer ware finish is applied to the food contact area, and a light and shade pattern (substantially different from the surface exposure of granules (useful minerals) and the coating thickness of the lacquer layer on the upper layer of the surface ( It is possible to provide a tableware with a novel design that has never been seen before, and the natural purification from useful minerals and the food purification effect by far-infrared radiation (far-infrared radiation, Negative ion emission, antibacterial action, deodorization action).
