Description

METHOD FOR MANUFACTURING HUMAN BONE POTTERY

Technical Field

[1] The present invention relates to a method for manufacturing a human bone pottery; and, more particularly, to a method for manufacturing a pottery, the method comprising forming a ware by mixing raw materials for a pottery with human bone and biscuit firing the ware and then coating the ware with a glaze to which the human bone is added in preparation.

[2]

Background Art

[3] Every human being is born, grows, works, gets older and finally goes back to the nature, and among all the creatures under the sun, it is the human being who endows the biggest meaning to death. Even if there are differences in procedures or methods according to regions or cultures, all the peoples have been holding the funeral ceremonies of their own.

[4] According to culture, climate and custom of a people, the funerals have been performed in various ways such as platform burial, aerial sepulture, water burial, cremation and interment. Recently, crementation is one of the funerals used most widely in the world.

[5] A conventional method of cremation is performed by burning a dead body and putting the human bone into a certain vessel and preserving the vessel in a charnel house. In this method, it is hard to collect and preserve the human bone, and the charnel house cannot be popular as human bone visually makes an ill impression, and also it is hard to preserve human bone in a state of powder for a long time.

[6] In other conventional methods, human bone is made into a diamond or a precious stone to be carried with or to be stored, or contained in an urn or a case which is made of materials including pottery, or a glass which human bone is sealed in is made into a mortuary tablet after recording a picture or a personal history therein.

[7] The method of preserving the human bone inside of glass has a problem that, in case of a transparent glass, human bone can be seen through the transparent glass, causing repugnance, and in case of keeping the human bone inside of an opaque glass, it is hard to design the picture or the personal history for the glass. Also, the value for preserving the human bone eternally is depreciated. So in most cases, a mortuary tablet is made.

[8] In case of human bone case, even a tight sealing lets some air remain therein and humidity flow therein. This results in putrefaction and accordingly bad smell. In case of processing human bone into a precious stone, it has problems that the cost is high and the original form of the human bone is deteriorated during the process of manufacturing the precious stone. In addition, people other than descendants in the direct line do not carry it due to the difference in their taste, or it is hard to tell predecessor to which the bone belongs after a long preservation term.

[9] Fig. 1 is a flowchart illustrating a conventional procedure of manufacturing a pottery. Referring to Fig. 1, raw materials are elutriated at step SlOO and dried after removing humidity and impurities at step Sl 10. And, a ware is formed at step S 120, an engobe is coated on the ware at step S 130 and various patterns are engraved on the ware at step S 140.

[10] After that, the ware is dried after putting inlaying materials in the patterns and performing a planarization at step S 150. After that, a biscuit firing is performed at step S 160, and after applying a glaze to the ware, a glaze firing is performed at step S 170.

[11] A pottery can be preserved to remain unchanged forever. And if a pottery is manufactured using the above, it is easy to tell who's the predecessor the human bone belongs to, as a picture or a personal history of the predecessor can be designed and recorded thereon. Also, people do not get bored of preserving the pottery for a long term as the pottery is manufactured as a work of art. One can substitute the pottery for a mortuary tablet or an ancestral tablet made of paper by retaining the human bone inside of the pottery without deforming the bone, and maintaining the pottery by side.

Mode for the Invention

[25] Before describing the embodiments of the present invention, the terms and words used in the specification and claims must not be interpreted in their usual or dictionary sense, but are to be interpreted as broadly as is consistent with the technical thoughts of the invention disclosed herein based upon the principle that the inventor can define the concepts of the terms properly in order to explain the invention in the best way.

[26] Accordingly, the embodiments described in the present specification and the construction shown in the drawings are nothing but one preferred embodiment of the present invention, and it does not cover all the technical ideas of the invention. Thus, it should be understood that various changes and modifications may be made at the time of filing the present application.

[27] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[28] Fig. 2 is a flow chart illustrating a process of manufacturing a human bone pottery in accordance with a first embodiment of the present invention. Referring to Fig. 2, the procedures up to step S260 of Fig. 2 are the same as the procedures up to step S 160 of Fig. 1, that is the biscuit firing procedure. After step S260, a glaze is prepared at step S270 and human bone at a powder state is added to the glaze at step S275 and agitated at step S280 to make a mixture thereof. It is followed by glazing and glaze firing at step S285. The mixture ratio of the glaze and human bone is 90-96% of base glaze and 4-10% of human bone powder.

[29] Fig. 3 is a flow chart illustrating a process of manufacturing a human bone pottery in accordance with a second embodiment of the present invention. Referring to Fig. 3, the procedures up to S320 are the same as the procedures up to the step S 120 of Fig. 1, that is a ware forming procedure. After step S360, the human bone powder is inserted into the ware through an air inlet at step S330, and afterwards, an engobe is coated over the ware at step S340 and various patterns are engraved on the ware at step S350.

[30] After that, the ware is dried after putting inlaying materials in the patterns and performing a planarization at step S360. Afterwards, a biscuit firing is performed at step S370 and a pottery is made by applying a glaze to the ware and glaze firing the ware at step S380.

[31] The ware is formed to have an empty space in its thick part such as a handle or a trunk of a turtle-shaped ware, so as to reduce weight thereof. At this time, an air inlet is made to prevent a crack or inflation due to air expansion during a fire burning process.

[32] In other words, in case of forming a thick ware such as a Virgin Mary statue or a

Buddha statue, it is essential to make inside thereof hollow and prepare an air inlet to the inside. In the present invention, the human bone powder is inserted through the air inlet into the hollow space of a pottery, which is made during a ware forming process corresponding to a condition of process from the ware forming process through the glazing process

[33] Fig. 4 is a flow chart illustrating a process of manufacturing a human bone pottery in accordance with a third embodiment of the present invention. Referring to Fig. 4, after elutriating raw materials at step S400, human bone powder is mixed with clay, a raw material of a pottery and alumina at step S410 and is made into a ware of a shape in accordance with a user's taste at step S420. The mixture ratio of the human bone powder and the raw materials of a pottery is human bone powder 25% : clay 65% : alumina 10%.

[34] And an engobe is coated over the ware at step S430 and various patterns are engraved on the ware at step S440.

[35] After that, the ware is dried after putting inlaying materials in the patterns and performing a planarizing process at step S450 and then a biscuit firing at step S460 are performed. And a pottery is made by glaze firing the ware after coating a glaze over the ware at step S470.

[36] As an article in a shape of an urn or a plate is not thick enough to form a hollow space inside thereof for human bone to be contained. For a method which forms a ware which is required by a user after coating the ware which is formed by mixing the human bone powder and the raw material for a pottery at a base, the thickest part, considering that there exists a problem of cracking when there exist impurities during a manufacturing process of a pottery or when air is included, the human bone powder should be one body with the raw material by repeating the process of elutriating raw materials. Even there exists a weak point that the process is complicated but there are strong points in that it is possible to form according to the specification of a user and that the original form of the human bone can be preserved.

[37] Fig. 5 is a flow chart illustrating a process of manufacturing a human bone pottery in accordance with a fourth embodiment of the present invention. Referring to Fig. 5, after elutriating raw materials at step S500, human bone powder is mixed with clay which is the raw material of a pottery and alumina at step S510 and is made into a ware of a shape in accordance with a user's taste at step S520. The mixture ratio of the human bone powder and the raw material of a pottery is human bone powder 25% : clay 65% : alumina 10%.

[38] And an engobe is coated over the ware at step S530 and various patterns are engraved on the ware at step S540. After that, the ware is dried after putting inlaying materials in the patterns and performing a planarizing process at step S550 and then a biscuit firing is performed at step S560.

[39] After a glaze is prepared at step S570, a human bone powder is added to the glaze at step S580, and after agitation for mixing raw materials with the glaze at step 590, the glaze is applied to the ware and a glaze firing is performed at step S600. The mixture ratio of the glaze and human bone is 90-96% of the base glaze and 4-10% of the human bone powder.

[40] Referring to the processes in accordance with the above embodiments, since calcium exists in a liquid state at a temperature above its boiling point which is obtained during a firing process, a ware should be formed to have a space for containing human bone so that the calcium in a liquid state would not overflow during the firing process.

[41] Human bone is composed of two thirds of inorganic compounds and one third of organic compounds, and the inorganic compounds are composed of 85% of calcium phosphates, 10% of calcium carbonates and other inorganic matters. Calcium phosphate is a salt of phosphoric acid and calcium and known as phosphate of lime. It is produced as a main component of apatite in nature and can be extensively found in bones of a vertebrate or in soil. It is used as an additive in lye, enamel, or a frosted glass, or used in tooth pastes or in pharmaceuticals. Calcium carbonate is a main component of a limestone, a marble, a chalkstone, a shell of an oyster or a coral, and used as an additive in various items such as ceramic and glass. When carbon dioxide is omitted during heating process, a white or light gray calcium oxide (CaO), which is called lime or quicklime, remains. [42] Calcium has an atomic number 20, an atomic weight 40.08, a melting point

842-848⁰C, a boiling point 1,487⁰C, a specific gravity 155 (2O⁰C) and carbon has an atomic number 6, an atomic weight 12.011, a melting point 3,55O⁰C, a boiling point 4,827⁰C. Since a temperature for a first firing is about 98O⁰C and a temperature for a second firing is about 1,24O⁰C, only calcium from calcium phosphate melts with the phosphoric acid volatilized and only calcium of calcium carbonate melts, resulting in a mixture of carbon and calcium.

[43] And, a portion of a small quantity of inorganic matters also remains after a firing process. As the temperature returning to a room temperature, the inorganic matters remain in an oxidized form or with the elements mixed. Therefore, calcium, carbon and other inorganic matters which are the main components of human bone canbe left overwithout degeneration or deformation.

[44] Considering that mixture ratio of raw materials of Bone China compound hard ceramics is bone ashes 6, chinastone (granite) 4, and kaolin 3.5, it makes no problem that a human bone powder is added to the raw material of a pottery. There are only usual problems in a process of manufacturing a pottery, like a crack which results from bubbles generated while heating.

[45] Human bone can be procured from a cremation which is a recent trend in funeral.

And it is possible utilizing human bones from a tomb made in former days, as there exist remnant human bones in many cases. Also, in case of a burial, a portion of fingernails, toenails and body hair which is a portion of a body can be used to manufacture a soul tablet.

[46] Fingernails, toenails and body hair have collagen as a main component, and collagen is a protein. Fingernails, toenails and body hair have collagen in common with skin tissue; and, collagen of fingernails, toenails and body hair is different from that of skin tissue in that a process of hardening causes the specific gravity of collagen to be reduced, whereby giving fingernail, toenail and body hair a relatively higher inorganic matter content than skin tissue. As a result, there is only complexity in manufacturing process that a small quantity of the inorganic matters remained after a first heatingmust be utilized.

[47] While the present invention has been described with respect to certain preferred embodiments, it will be apparent to those skilled in the art that various changes and modifications may be made without departing from the scope of the invention as defined in the following claims.
