Abstract

In order to provide a food container that is a ceramic product that can fully utilize the inherent properties of germanium, the present invention uses a base material for manufacturing ceramics containing germanium components in which the proportion to the total weight is 10 to 50% by weight. The present invention relates to a method for producing a food container using a glaze containing germanium components in which the proportion to the total weight is 30 to 70% by weight. The food containers obtained according to such methods exhibit the advantages due to the inherent properties of germanium, such as warmth, heavy metal removal and toxic degradability, especially since glaze contains large amounts of germanium. Even though it is well washed, it shows excellent efficacy in terms of environmental protection.

Description

[Name of invention]

Manufacturing method of food container using glaze mainly containing germanium

Detailed description of the invention

[Field of Invention]

The present invention relates to a method of manufacturing porcelain, and in particular, to a food container that is completed by applying a glaze containing germanium as a main component to the outside of the food container manufactured using a ceramic material (earth used as a material for producing ceramics). It relates to a manufacturing method.

[Background of invention]

Widely used as food containers include aluminum containers and stainless containers. Such containers have the advantage of being easy to purchase materials, relatively simple to manufacture and relatively high in mass productivity. Nevertheless, the phenomena of returning to the pottery containers that prevailed in the past are becoming deeper. Underlying such a regression phenomenon, there is a reason why, despite difficulties in purchasing a material and manufacturing process, advantages due to the inherent properties of such a ceramic container cannot be ignored.

However, such regression is not intended to restore the past, but efforts are being made to develop products that are appropriately improved based on modern technological advances and considering modern lifestyles and dietary cultures.

Germanium (Ge) contained in the food container can provide a very hygienic food container by neutralizing the heavy metals contained in the food and accelerate the process of decomposition and removal of toxic or other contaminants. In addition, the food container manufactured using a base material containing such germanium (Ge) component is excellent in heat retention, so that food can be preserved for a long time, and exhibits excellent efficacy in cooking such as baking of food.

The specification of 1989 patent application No. 8419 describes a method for producing a food container using a ceramic porcelain-containing base containing such germanium (Ge). The methods described in the specification of such patent applications include at least 66% silicic anhydride, at least 10% aluminum oxide, at least 2.8% iron oxide, at least 3.7% potassium oxide, at least 2.8% calcium oxide, at least 3.3% sodium oxide and other small quantities. 50:50 heat-resistant clay powder mainly composed of pink clay or sandy clay is mixed with ganban stone composed of elemental or unavoidable impurities and mixed powder containing about 10% by weight of germanium (Ge) -containing clay powder. A food container is prepared by using porcelain-produced base material mixed with a ratio of about 80% and glaze composed of about 80% of wort rock powder, about 10% of silica and about 10% of limestone. Component analysis values of general elvan are as shown in Table 1.

Therefore, the porcelain manufacturing base used in the method described in the above patent application 8419 will contain less than about 5% of germanium (Ge), and the glaze will contain less than 0.5% of germanium (Ge). It is difficult to expect that the effects of the inherent properties of germanium (Ge) will be fully exhibited in the food containers prepared using the base and glaze containing such a small amount of germanium (Ge).

[Overview of invention]

The present invention is intended to produce a food container that is fully exhibited the efficacy of the inherent properties of germanium (Ge).

To this end, in the present invention, not only the preforms of food containers are manufactured by using porcelain manufacturing materials containing a sufficient amount of germanium (Ge), but also by applying a glaze containing germanium (Ge) as a main component on the surface of such preforms. A method of preparing a food container is proposed. More specifically, in the present invention, silicic anhydride (SiO), aluminum oxide (AlO), iron oxide (FeO, FeO), magnesium oxide (MgO), sodium oxide (NaO), potassium oxide (KO) and manganese oxide (MnO) Based on the primary mixture containing calcium oxide (CaO) and phosphoric anhydride (PO), the powder of ore containing germanium (Ge) as a main component is mixed at a ratio of about 10 to 50% by weight of the total weight. Make. Using such porcelain-making bases, the food container is molded and dried in a known manner, followed by first baking. In addition, the glaze is made by mixing germanium (Ge) in a proportion of about 30 to 70% by weight of the total weight with respect to the first mixture containing feldspar, silicic anhydride, limestone, talc, white earth, barium and zinc. As described above, the glaze is applied to the surface of the molded food container, and the chaebol is roasted in a known manner.

The glaze application and chaebol roasting process as described above may be repeated as necessary.

The food containers thus obtained contain not only a sufficient amount of germanium (Ge), but also particularly, the glaze contains a larger amount of germanium (Ge), and thus the inherent properties of germanium (Ge) described above. Advantages due to the nature of can be exhibited intact.

In particular, since the glaze containing a large amount of germanium (Ge) is used, it is not only excellent in heat retention, heavy metal removal ability, and harmful substance decomposition ability than conventional ceramic products, but also does not need to use detergent when washing food containers after use. It is an advantage that the back is washed clean. Such cleaning benefits eliminate or reduce the need for detergents and thus provide an additional benefit of excellent efficacy in terms of environmental conservation.

EXAMPLE

Now, an embodiment of a method for preparing a ceramic manufacturing device and glaze and preparing a food container according to the present invention will be described.

First, as shown in Table 2, a base for manufacturing ceramics is prepared, and also as shown in Table 3, a glaze is prepared.

[Example 1]

The porcelain-making base material prepared as described above was kneaded to form a plate having a diameter of about 20 cm (8 inches). Such dish moldings were carved using a carving knife and then dried in a drying chamber. Appropriately dried dish moldings were baked by first roasting at a temperature of about 900 ° C. for about 6 to 8 hours. Appropriate coloring and painting were performed on the fired dish moldings. Thereafter, the glaze prepared as described above was applied to the surface of the dish molding, and then the chaebol was roasted for about 11 to 13 hours at a temperature of about 1270 ° C to 1320 ° C to complete the dish. The finished product weighed 1000g. The materials required were 370g germanium powder, 250g white clay, 95g clay, 200g pottery stone and 85g silicic acid anhydride.

[Example 2]

Rice porcelain was prepared using the same porcelain manufacturing base and glaze as in Example 1 described above, and undergoing the same manufacturing process. The finished product of the cooked rice was 400g in weight. The materials required were 210g of germanium powder, 50g of clay, 40g of clay, 80g of pottery stone and 20g of silicic acid.

Dish and rice prepared as described above was excellent in warmth, heavy metal removal ability and harmful decomposition ability than any conventional ceramic products, it was well washed even without using detergent.

Food containers that can be manufactured using porcelain manufacturing bases and glazes according to the present invention can manufacture most of the kitchen containers as well as grounding or rice bowls, the base of the porcelain manufacturing bases and glazes to be used in the manufacture of each container The component content can be appropriately adjusted in consideration of the properties particularly required according to the use of each container.
