[0006]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a method for firing a pottery according to the present invention will be described with reference to the illustrated embodiment. [I] Firing Method FIG. 1 is an overall flow chart showing the firing method of the present embodiment, and FIG. 2 is a diagram showing the mixing ratio of clay and charcoal described below.

As shown in FIG. 1, the firing method of the present embodiment includes (1) a process relating to Ryukyu gray clay (referred to as “Kucha” in the Okinawan dialect) and the like, and (2) Ryukyu limestone (coral) and the like. (3) a step of producing charcoal from old wood, (4) a step of producing tire charcoal from old tires, and (5) a step of blending the above-mentioned clay, charcoal, etc. in various proportions; (6) a step of kneading and shaping the clay or the like after compounding, and (7) a step of firing after drying. Hereinafter, each step will be described in order.

(1) Process relating to Ryukyu gray clay or weathered zone clay or weathered zone soil clay of Ryukyu limestone First, the collected Ryukyu gray clay or weathered zone clay of Ryukyu limestone or weathered zone soil clay of Ryukyu limestone is sufficiently supplied in the sun. (Step S1), finely crushed with a mallet (Step S2), and sieved using a sieve of about 16-14 mesh (Step S3).

Here, the Ryukyu gray clay and its weathered zone clay (referred to as "Jargar" in the Okinawa dialect) are called, for example, the Shimajiri Group Middle Belt Uniform Gray Clay in Okinawa, and are produced in the southern region of Okinawa. The particles are fine and easy to adjust to water, have excellent tackiness, and are easy to mold with plastic clay.
Also, weathered zone soil clay of Ryukyu limestone (Shimajiri Merge, Okinawa)
Is produced in the southern and northern parts of Okinawa and is mainly a collection of calcium carbonate crystals (calcite). When mixed with clay and heated, it has the effect of accelerating hardening together with the compounded substances. Incidentally, general clay (for example, clay easily available on the mainland) may be used. In the case where a large amount of Ryukyu gray clay or the like is crushed in step S2, a crusher is used.

(2) Process relating to Ryukyu limestone Ryukyu limestone is baked and burned in advance (step S1).
0). Then, the burned Ryukyu limestone is finely crushed (step S11), and sieved using, for example, a 22-23 mesh sieve (step S12).

Here, the reason that the Ryukyu limestone was preliminarily baked and burned in step S10 is that, in this way, it is easy to pulverize, to prevent heat shrinkage of the fired body after firing, and to have heat resistance. This is because they have the effect of preventing cracking and accelerating hardening. Ryukyu limestone, like the weathered zone soil clay, is produced in the central and southern parts of Okinawa and throughout northern Japan. It is mainly a collection of calcium carbonate crystals (calcite). It has the effect of promoting it. In addition, instead of Ryukyu limestone, general limestone [for example, mainland (Chichibu region, Saitama Prefecture, etc.)
Which are easily obtainable by the above method] may be used.

(3) Process relating to charcoal Using the "carbonizing furnace" of the patent invention, charcoal is produced by carbonizing old wood, sawdust, coconut shells and the like (step S2).
1) The charcoal is finely crushed (step S22) and sieved (step S23). Here, the size of charcoal sieves varies depending on the type of baked goods, so in the case of a container for storing water (such as a vase), a fine particle size of 2 is used.
Use 2-16 mesh size, for water purification, for ornaments,
In the case of containers for use in humidity control, food storage, etc., a slightly coarse 2-3 mm mesh sieve is passed through. In addition, in the case of a fishing reef described later, a mesh of about 3-10 mm,
3-10m for catch containers (eg octopus pots)
Filter through an m-mesh screen.

(4) Process relating to tire charcoal Using the "carbonizing furnace" of the patent invention, the old tire is carbonized to produce tire charcoal (step S31), and the oil adhering to the tire charcoal is removed (step S31). (Step S32), the tire charcoal after oil removal is finely crushed (step S33), and sieving is performed (step S34). Here, as the oil removing means in step S32, tire charcoal is put into a carbonization furnace (preferably the carbonization furnace of the above-mentioned patent invention), and the oil is removed for about 6 hours.
It is recommended to heat dry at 00 ° C. for about 3 hours, or to wash the charcoal by boiling in sodium hydroxide. Also, as in the case of the above-mentioned charcoal, in the case of a water storage container (such as a vase), a filter having a fine particle size of about 22-16 mesh is used in step S34. In the case of a container for an ornament, humidity control, or the like, a coarse coarse 2-3 mm mesh sieve is passed. Further, in the case of a fishing reef described later, it is about 3-10 mm mesh, and in the case of a fishing vessel (for example, an octopus pot), it is 3-10 mm.
The mesh is sieved.

(5) Mixing process of clay and charcoal The mixing ratio of clay and charcoal is shown in FIG. As shown in FIG.
Based on Ryukyu gray clay (Kucha) or its weathered zone clay (Jagar) or Ryukyu limestone weathered zone soil clay (Shimajiri Merge), in each case 20 to 40% by weight (hereinafter, weight is omitted). The weight of Ryukyu limestone (coral) is 10 to 20%, and any one of charcoal or tire charcoal or mixed charcoal (three types are equivalent) is 20 to 40%.

For example, the mixing ratio (a) shown on the right end of FIG.
In the case of Ryukyu gray clay (kucha), the ratio of one cup (40%), Ryukyu limestone (coral) is 20% (about 1/3 of the cup), charcoal or tire charcoal or mixed charcoal. Full glass (40%). It should be noted that although Kucha and Jagal have almost the same adhesiveness, Shimajiri Merge has poor adhesiveness, so it is better to use it in combination with Kucha and Jagal. Since neither charcoal has tackiness, it is better to use clay with good tackiness.

[0016] In addition, baked goods for the purpose of deodorization (for example,
In the case of particles for water purification, containers for storage, etc.), for example, 40% of kucha, 10% of coral, and 50% of tire charcoal may be mixed. That is, in the case of deodorizing, the strength of the grilled product does not need to be regarded as important and the deodorizing effect is mainly used, so that the proportion of charcoal is increased.

When used as a pot for ikebana,
It is advisable to put the pottery particles in the pot together with the water. In this case, the size of the pottery particles is, for example, about 5 mm to 30 mm, and each of them does not have to have the same size. Further, when a particle having a size of about 5 mm to 10 mm is formed and fired, the same effect as when the particle is reduced can be obtained. That is, as shown in FIGS. 3 (A) and 3 (B), the pottery particles 1 having a diameter of about 30 mm
Penetrate a hole having a diameter of about 10 mm from the direction. In this case, since the surface area inside the particles increases, the particles 1a to 1e substantially having a diameter of about 10 mm (illustration of a shaded portion is omitted) 8
It is possible to obtain the surface area of each piece. In addition, as a result of use, if the effectiveness of the particles is reduced due to clogging,
By firing in a carbonization furnace and regenerating the particles, the same effect as that of a new product can be obtained.

(6) Kneading / Molding Step Water is added in the respective mixing ratios of clay, charcoal and the like shown in FIG. 2 to stir and knead (step S41). On this occasion,
If the pulverized coal is floating, it becomes difficult to stir, so if a small amount of surfactant is added, the pulverized coal smoothly dissolves in water, and the stirring becomes easy. When a small amount of salt is added, the hardening of the clay molding in the next firing step (step S43) can be promoted. Next, the stirred and kneaded clay, charcoal, and the like are formed (step S42). Here, a specific example of the molding method will be described.

[Repeated use of predetermined form frame]
In the case where the predetermined form is repeatedly used by a manual molding method or the like, a gypsum form is suitable, and in the case of repeatedly performing press forming, a mold forming frame and a press machine may be used. [Granular molded body] When a granular molded body is prepared, an extruder or a pressure molding machine is preferably used. [Complex fired material] In the case of a complicated fired material, first, wood,
A predetermined model is formed using straw, sawdust, used paper, used cloth, or the like, and the mixed clay created by the method up to step S41 is pasted on the surface of the model to perform hand pressing. In this case, the lip is made removable using plaster or bentonite,
A separating material is applied to the surface, and the clay is pressed by hand. In the case of manual molding, potter's wheel may be used according to the shape of the fired product.

(7) Firing Step After the mixed clay containing charcoal is formed by the means described in step S42, if the mixed clay containing charcoal becomes semi-dry, various decoration, finger drawing and engraving are performed using a predetermined tool. , Carving lines. When the model is used, after the charcoal-containing mixed clay is dried, the gypsum and bentonite are removed, and the wood, straw, etc. are left as they are and the clay molding is used together with the carbonization furnace (carbonization furnace) of the patent invention. ) Is performed as described below. Charcoal-containing ware is burnt at high temperatures, so charcoal is ashed.
Do it only once.

After the completion of the dry distillation firing, carbides such as the wood and straw are removed. After removing the wood and the like, painting is performed on the fired material using a paint or a natural plant with a brush or brush. For example, the painting, the font, and the like are engraved on the molded body so as to be engraved, and after firing, the engraved grooves are colored. That is, the picture or character is prevented from rising from the fired body. Also, if the picture or font is to be embossed, it must be embossed in a molded body. If the same picture or font is to be used repeatedly, it is molded into a plaster mold or metal mold and used repeatedly.

Next, the firing process will be described in detail. The carbonization furnace of the patent invention has an inner furnace inside the outer furnace, and is disposed in the inner furnace when the clay molded body is dried. In the case of this arrangement, the inner and outer furnaces are hermetically sealed by using a loading mounting plate and a carry-in shelf at predetermined intervals. The heating means of the carbonization furnace may be a heavy oil heating method or a kerosene heating method, but the temperature can be easily adjusted by the electric heating method.

After placing the clay molded body in the carbonization furnace, FIG.
As shown in (2), the temperature is gradually increased, and the outer furnace is heated at a heating temperature of about 500 to 800 ° C. After a lapse of 2 to 3 hours, moisture is discharged from the clay molded body, and after a lapse of about 4 hours, carbonization of organic substances contained in the clay starts, and hardening of the clay, limestone and carbon starts. At this time, aluminum, iron, magnesium, alkali metal and alkaline earth metal contained in the clay are combined with aluminum, calcium, magnesium, zinc, copper and iron contained in carbon, lime and tire charcoal and heated. It is believed that the substrate shrinks and the pores shrink, causing the particles to approach and stick together to strengthen.

Before the lime is vitrified, carbonization and hardening of the organic substance are completed in about 5 to 8 hours. The organic matter in the clay is carbonized into a porous state, and in addition to the porosity of charcoal and the like, the effect of the porous ware is further increased, that is, countless microorganisms (organic matter) contained in the clay are also converted into countless pores by thermal decomposition. Thus, the effect of increasing the adsorptivity and surface area of the whole baked product can be enhanced.

When the internal temperature of the inner furnace is about 200 ° C., the carbonization and hardening of the organic matter in the mixed clay containing charcoal are completed. When heating is further continued and the inside of the inner furnace is raised to about 400 to 600 ° C. in an oxygen-free atmosphere, carbon dioxide discharged from limestone is activated to activate the charcoal, and the charcoal is activated.
Produces more porous charcoal. In addition, since it heats in an oxygen-free atmosphere, charcoal does not ash.

[II] Effects of the Embodiment The charcoal-containing baked goods are manufactured through the steps described above, and water is added to the charcoal-containing ware to increase the alkalinity. That is, in addition to the alkaline substances of charcoal and tire charcoal, limestone is an alkaline substance, and the alkaline substance of water can be strengthened by these alkaline substances.

Further, since the concentration of hydroxide ions can be increased by the alkaline substance, a bactericidal action can be provided, and it becomes difficult for bacteria to inhabit the water. In addition, microorganisms inhabit the pores of the porous porcelain and decompose organic substances such as acetaldehyde, which causes bad odors when the concentration of ethylene gas or carbon dioxide, which is a hormone that promotes absorption by plants and flowers, increases. Control and prevent corruption. Further, the water in the container (pot) containing charcoal is hardly rotten by preventing oxidation and supplying minerals with the alkaline water.

[Experiment 1: Prevention of rot] Water (tap water, well water, etc.) was placed in the conventional pottery container and the charcoal-containing pottery container of the present embodiment, respectively, and experiments were conducted using plants and flowers. As a result, conventional containers have been used for 15 days to 2
On the other hand, the odor was generated on the 0th day, but in the case of the charcoal-containing grilled product of this embodiment, almost no odor was felt even after about 3 months, and the odor started to be emitted after 4 to 5 months. In other words, the charcoal-grilled ware has about seven times longer plant and flower life than the conventional ware.

[Experiment 2 ... Growth promotion] When water (tap water, well water, etc.) was put in a charcoal-containing pottery container and a conventional pottery container, and the Japanese radish was cultivated in water at the same time, it grew to about 10 cm, but it contained charcoal. It was confirmed that pottery grew two days earlier.

[Experiment 3: Prevention of rot] The commercially available square bread in the charcoal-baked container (jar) of this embodiment and the square bread in a plastic container at room temperature As a result of comparison, the bread put in the charcoal ware pot did not produce mold for more than one year, whereas the plastic container produced mold and rot in 1 week to 10 days.

[Experiment 4 Deodorizing Effect] Using the roasted particles (particle size: about 10 to 30 mm) of the present embodiment, waste oil,
When livestock sewage and the like were filtered and purified, the deodorizing effect was remarkable. For the purpose of deodorizing, it was more effective to use the charcoal-containing particles containing tire charcoal than to use the charcoal-containing particles containing charcoal.

[Experiment 5: Effects on the Living Environment such as Deodorization and Humidity Control] When a pot is placed as an ornament in a house, it is better to put charcoal-containing pottery particles in the pot. That is, for example, if a large number of pottery particles are put in a pottery pot in a house rather than putting the pottery pot alone in a house for viewing, the pottery particles will be in a spread state, so the surface area will increase, and the adsorption power will increase. (Deodorization), has the effect of humidity control, and can improve the living environment. In addition, there is a means for adsorbing a bad smell or the like by using pulverized coal obtained when pulverized charcoal, but this means may cause the pulverized coal to be scattered. Also, even if the pulverized coal is wrapped in a sandbag or nonwoven fabric and placed under the floor or in a room, it may be scattered little by little, which is not preferable for the living environment.

[Experiment 6: Prevention of Rot of Ikebana Water] When the flowers were alive in a state where the pottery particles according to the present embodiment were placed in the ikebana pot, it was found that the water did not easily rot and lasted a long time. Even if the above-mentioned pottery particles were put into (general ceramics) and a flower was activated, the effect that water did not easily rot was obtained.

[Experiment 7: Application to Fishing Reefs and Fishery Tools] It was confirmed by experiments that agglomerates tended to grow in a relatively short period of time when a lump of charcoal-containing baked goods was left in freshwater or seawater. Applications include, for example, fishing reefs. A small fish settles in a reef submerged under the sea, and a large fish gathers following this small fish. Fishermen will set up artificial reefs to catch this large fish. However, since conventional fishing reefs are made of cement, it is difficult for algae, shells, and the like to adhere thereto.

Therefore, if a fishing reef is made of the charcoal-containing grilled food of the present invention and submerged in seawater or freshwater, algae, shellfish and the like can be attached in a short period of time. May be used for octopus pots, shrimp nests, and eel fishing. For example, a conventional octopus pot was made of ordinary unglazed pottery, but if it did not take 3 to 4 years, algae and shells would not adhere to the octopus pot, and it would take 3 to 4 years before the octopus was caught by the octopus pot. I often had to wait. However, if the octopus pot is made of the charcoal-baked food of the present invention, the algae will adhere in 5 to 6 months, so that the catch (octopus landing) can be increased in a much shorter time than in the conventional octopus pot. .
