[0004]
[Problems to be solved by the invention]
The Amagi anti-firestone produced at the foot of the Amagi Mountains in the Izu region of Shizuoka Prefecture is a closed cell in which obsidian, which is a rough stone, is heated at an ultra-high temperature of 13,000 to 15000 ° C and rapidly cools down. The main component is 73 to 77% of silicic acid and 13 to 15% of alumina, and the two components become a fusion bond due to high heat and do not separate.
And since anti-firestone is heated at high temperature, far infrared rays are emitted in a larger amount than other stones.
[0005]
Due to the far-infrared emission characteristics, water molecules are made finer, and harmful gases such as CO, CO ₂ , and SO ₂ are not taken in, and contaminants mixed in the water are removed. It becomes weakly alkaline and has a purifying action.
[0006]
In addition, the vibration of far infrared rays weak energy of electromagnetic waves contained in the sunlight of 4 to 14 microns cuts the polymerization of long water, and the water in the body also increases the specific gravity by the polymerization and the adhesion to the cell membrane is good. In addition, penetration into each cell membrane is also improved, and it is effective not only for promoting health but also for treating chronic diseases, and activates cells of the human body, further strengthening and activating cell diseases.
In addition, far infrared rays have antibacterial, deodorizing and antifungal functions, and silicates (silica) have antibacterial, antibacterial, antifungal and deodorizing actions. There is no water.
[0007]
In view of the above, the present invention has a water purifying effect by using anti-fire stone from Amagi, and also has a bactericidal, antibacterial, antifungal, and deodorant properties, and has a blackish candy-like tone. It is an object of the present invention to provide a glaze for ceramics exhibiting the above, and to provide an elementary fired product using an anti-fire stone having a water purification action and a bactericidal property, an antibacterial property, an antifungal property and a deodorant property.
[0008]
[Means for Solving the Problems]
To achieve the above object, the glaze using the anti-firestone of the present invention according to the first aspect of the present invention is an anti-firestone powder containing 50% of an anti-firestone powder crushed to 30 microns and excluding iron, and an anti-firestone which is crushed to 1 to 5 microns. It is characterized by comprising a liquid material in which water is mixed with 47% of powder and 3% of synthetic paste.
[0009]
By using the above glaze, 50% of the powder of the anti-firestone excluding iron and 47% of the powder of the anti-firestone containing iron, out of the 47% of the powder of the anti-firestone containing iron, Is contained only about 7%, so the color of the glaze does not turn black, it becomes a blackish candy color, and the glazed porcelain does not melt out even if fired at a temperature of 1300 ° C or more. Instead, it has a celestial appearance.
Also, by using the anti-firestone, the powder of the anti-firestone can achieve a heavenly tone without mixing several kinds of raw materials as in a general glaze.
[0010]
In addition, since the powder of the anti-firestone from which iron has been removed is finely pulverized to 30 microns, it can be easily removed with a magnet when removing iron in the powder.
In addition, anti-firestone emits far-infrared rays in a larger amount than other stones and also contains a lot of silicic acid. Therefore, water-purifying action, sterilization, antibacterial, antifungal, deodorant, etc. action by the properties of far-infrared radiation and silicic acid If a glazed teacup, tableware, or the like is used, the action of the composition will make the contents mellow and sufficiently enhance the physiological activity in the body, which is beneficial for health.
[0011]
Next, the fired fired product using the anti-firestone of the present invention is formed by mixing 20 to 30% of powder of anti-firestone crushed to 1 to 5 microns with clay and firing at a temperature of about 1300 ° C. It is characterized by comprising.
[0012]
By making the above-mentioned fired element, the fired article has an action of purifying water, sterilizing, antibacterial, fungicide, deodorizing and the like due to the properties of the far-infrared radiation and the properties of silicic acid. Therefore, if the unfired shaped article is formed into a sewage treatment tank or a diffuser pipe of a water tank, water purification is promoted.
In addition, if the unbaked product is molded into a teacup, it has far-infrared radiation characteristics and silicic acid characteristics, and the taste of the contents is also mild.
Also, since 20-30% of the powder of anti-firestone crushed to 1 to 5 microns is mixed with clay, it does not lose its shape even when baked at a temperature of about 1300 ° C., and the strength of the product is large. .
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
