JPH0710595A - Biologically active molding - Google Patents

Abstract

PURPOSE:To improve the contact efficiency of water and pearl and facilitate the elution of the biologically active components in the pearl into the water by consisting the biologically active molding of a porous glaze burnt layer mixed with pearl powder and a base material having a specific shape. CONSTITUTION:The pearl powder is mixed with glaze, such as lead glaze, frit glaze, bristol glaze and porcelain glaze. The mixing ratios are usually so set that the solid component of the glaze: the pearl powder attains 80:20 to 5:95 by weight. The pearl powder may be previously subjected to a heating treatment at about 400 to 1100 deg.C before mixing. The mixture is applied on a base material consisting of pottery body, metal, pottery, enamel or the like molded to a specific shape and is then burnt, by which the glaze firing layer is formed. Combustible powders, such as wooden flour and plastic powder, are added into the glaze at this time. Cracking is caused in the glaze firing layer at the time of cooling after burning by utilizing a difference in coefft. of thermal expansion between the base material and the glaze. The glaze burnt layer is formed porous by a method of obtaining the glaze burnt layer of the matte tone by firing at a temp. below the m.p. of the glaze, etc.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a molded article having biological activity.

[0002]

2. Description of the Related Art Conventionally, pearls have a biological activity, but it has been found that such a biological activity of pearls is enhanced by heating, and ceramics using glaze mixed with pearls are provided. (Japanese Patent Publication No. 4-68250).
When water is added to such a ceramic, bioactive components mainly composed of calcium are eluted from the pearls contained in the glaze firing layer, and this water has a health promoting action on plants and animals, a growth promoting action, a pest preventing action, It comes to have various bioactive effects such as a freshness-retaining effect.

[0003]

However, in the conventional ceramics, the pearls are confined in the glass layer which is the glaze firing layer, so that the elution of the bioactive ingredient from the pearls is hindered and the pearls are dissolved in water. It was necessary to keep the water and the ceramics in contact with each other for an extremely long time in order to give an activating effect.

Means for Solving the Problems As a means for solving the above-mentioned conventional problems, the present invention comprises a bioactive substance comprising a porous glaze firing layer mixed with pearl powder and a base material formed into a predetermined shape. A molded article is provided.

The glaze used in the present invention includes all kinds of glazes such as lead yu, frit yu, bristol yu, and porcelain yu.

The substrate used in the present invention includes
There are ceramic bases, metals, ceramics, enamels, etc. The base material is previously formed into a predetermined shape such as a container shape, a plate shape, or a pellet shape.

In the present invention, pearl powder is mixed with the glaze, and the mixing ratio is usually 80:20 to 5:95 by weight ratio of solid glaze solid: pearl powder. Also, before mixing the pearl powder into the glaze, 400-1100 ° C
The heat treatment may be carried out at a temperature in the range of a certain degree.

To apply the above-mentioned glaze to the above-mentioned base material, a general method such as dipping, pouring, spraying, sprinkling, screening, coating, volatilization, etc. is applied. Glazing may be performed on the entire surface or only a part of the substrate. The glaze is applied to the base material and then fired to form a glaze firing layer. In order to make the glaze firing layer porous, wood powder in the glaze, flammable powder such as plastic powder is added. Method, a method of causing cracks in the glaze firing layer at the time of cooling after firing by utilizing the difference in thermal expansion coefficient between the base material and the glaze, a mud-like glaze firing layer by firing at a temperature below the melting point of the glaze There are ways to get it.

[0009]

In the bioactive layer of the present invention, since the pearl powder mixed glaze firing layer formed on the substrate is porous, for example, when water is brought into contact with the bioactive layer, water is mixed in the glaze firing layer. The contact efficiency with the pearls is greatly improved, and the bioactive components in the pearls are easily dissolved in water.

【Example】

[Example 1] Bristol glaze was poured over the entire surface of a pottery base molded into a container shape, baked at 1190 ° C, and after cooling, a frit glaze containing 30% by weight of pearl powder was partially applied with a brush. If the frit glaze is glazed and then fired at a temperature of 850 ° C. which is lower than the melting point of the frit glaze, a mud-like glaze firing layer composed of the frit glaze containing the pearl powder is formed on the surface of the pottery. If you put water in the above container and breed seafood (shellfish) in it, you will not get sick and will grow faster. In addition, when beverages such as sake, tea, and coffee are put in the above-mentioned container and the beverage is drunk, the taste becomes mild and the taste is improved.

Example 2 A frit glaze containing 35% by weight of pearl powder is partially applied by spraying on the surface of an enamel container. The frit glaze is different from the coefficient of thermal expansion of the enamel container. After glazing, it is baked at 975 ° C. and cooled. During the cooling, fine cracks are generated in the pearl powder-added frit glaze baked layer due to the difference in coefficient of thermal expansion between the enamel layer and the pearl powder-added frit glaze baked layer. If you put water in such an enamel container and let it stand for 30 minutes before drinking it, it will be very effective for disease prevention and health promotion. In addition, the enamel container has the same beverage taste improving effect as the container of Example 1.

[Example 3] Bristol glaze prepared by mixing 15% by weight of wood powder and 30% by weight of pearl powder was poured onto a vase-shaped pottery base and baked at 1190 ° C. During firing, the wood flour is burned and a combustion gas produces a porous glaze firing layer. When water is placed in the above vase to arrange flowers, the freshness of the flowers is maintained and the retention of flowers is greatly improved.

[0013]

Therefore, according to the present invention, a molded product having useful biological activities such as health promoting action, growth promoting action, pest preventing action, freshness keeping action, taste improving action, etc. can be obtained.
