Description

Jewelry containing biological samples and method for manufacturing the same

[0001] The present invention relates to jewelry including a biological sample and a method for manufacturing the same, and more particularly, to jewelry including a biological sample such as human hair, fingernails, toenails, teeth, bones, etc. and a solid component including silver, and to a method for manufacturing the same, which is capable of manufacturing the jewelry using a biological sample of oneself or a loved one and having a mechanical strength above a certain level, thereby providing a memory through the jewelry manufactured using the biological sample of oneself or a loved one, enabling it to be stored semi-permanently and thus providing psychological satisfaction, and satisfying the value as jewelry and maximizing consumer preference.

[0002] In some countries, it is customary to preserve biological samples such as human hair, fingernails, toenails, teeth, and bones as a part of that person's memory or as religious relics. Traditionally, citizens who supported the king would wear the dead king's hair as a symbol of remembrance and political unity. This custom later continued to be practiced when mourning the death of a loved one, with ornaments containing the deceased's hair and decorated with images symbolizing death, such as a small coffin, a skull, an hourglass, or a grave shovel.

[0003] Additionally, in the modern art world, attempts are being made to commemorate the deceased by the bereaved family members creating jewelry using biological samples such as hair and teeth left behind by the deceased, or by creating jewelry using biological samples of loved ones or celebrities.

[0004] However, the conventional method of manufacturing jewelry using human biological samples in their original form has limitations in practical use due to the following problems.

[0005]

[0006] First, processing biological samples such as hair, fingernails, toenails, teeth, and bones into jewelry can be repulsive to some people. In particular, methods that directly attach large quantities of biological samples to jewelry pose a risk of deterioration or decay due to the absorption or adsorption of moisture, foreign substances, or bacteria from the surrounding environment, resulting in the generation of an unpleasant odor or the destruction of the biological sample itself by pests. To address these issues, methods have been disclosed that preservative biological samples such as hair before manufacturing them into jewelry. However, even in this manufacturing method, the shape of the biological sample is incorporated into the jewelry, making it unsuitable for everyday wear or use.

[0007]

[0008] Second, to address the aforementioned issues, attempts have been made to extract and process DNA from biological samples. However, such processing requires a prior DNA storage method. Common DNA storage methods include isolating and drying DNA from biological samples, or storing it in ethanol at room temperature. However, the DNA obtained through these methods is not visualized and cannot be seen with the naked eye. Furthermore, long-term storage outside of specialized laboratories presents significant technical challenges.

[0009]

[0010] Third, there have been attempts to extract biological elements from human biological sample makeup and inject them into artificial gems such as artificial rubies or artificial diamonds as a method for manufacturing jewelry that can be produced in a general environment rather than a laboratory environment without using the biological sample as is. However, the cost required for the process of combining biological elements into artificial gems is equal to or more expensive than that of processing natural quality gems, so commercialization is limited.

[0011]

[0012] Accordingly, the present applicant has provided a method for manufacturing jewelry by processing a biological sample so as to reduce the disgust that may occur when using a biological sample as is according to a conventional method when manufacturing jewelry using a biological sample, which is a part of the body, to forever remember the deceased or a loved one, and has completed an invention for jewelry including a biological sample that can be manufactured into jewelry including a solid component including silver and a biological sample such as human hair, fingernails, toenails, teeth, bones, etc., but can provide psychological satisfaction by having a certain level of mechanical strength or higher so that it can be stored semi-permanently, and can satisfy the value as jewelry to maximize consumer preference.

[0013] The present invention has been devised to overcome the above-described problem, and the problem to be solved by the present invention is to provide jewelry and a method for manufacturing the same that can reduce the disgust that may occur when using a biological sample as is when manufacturing jewelry using a biological sample, which is a part of the body, to forever remember the deceased or a loved one.

[0014] In addition, another problem to be solved by the present invention is to provide jewelry and a method for manufacturing the same, which can be manufactured using biological materials such as human hair, fingernails, toenails, teeth, bones, etc., and jewelry containing solids including silver, but which can have a certain level of mechanical strength that can prevent breakage or deformation.

[0015] In addition, another problem that the present invention seeks to solve is to provide jewelry including a biological sample and a method for manufacturing the same, which can provide psychological satisfaction by making the jewelry manufactured using a biological sample of a loved one a memory and allowing it to be stored semi-permanently, and which can satisfy the value as jewelry and maximize consumer preference.

[0016] The present invention provides a method for manufacturing jewelry, comprising a first step of obtaining a combustion compound containing carbon and calcium phosphate from a biological sample, a second step of mixing the combustion compound and a solid containing silver to obtain a paste, and a third step of sintering the paste produced by the second step, in order to solve the above-described problem.

[0017] In addition, according to one embodiment of the present invention, the biological sample of the first step may be characterized by being at least one selected from the group consisting of hair, fingernails, toenails, teeth, and bones.

[0018] Additionally, the first step may be characterized by thermal decomposition at a temperature of 500 to 800°C for 20 to 40 minutes.

[0019] In addition, the solid content including silver in the second step may be characterized by including 64 to 89 wt% of silver particles, 10 to 30 wt% of organic solvent, and 1 to 6 wt% of glass powder with respect to the total paste weight.

[0020] In addition, the combustion compound of the second stage may be characterized in that it is included in an amount of 1 to 5 wt% with respect to the total paste weight.

[0021] Additionally, the third step may be characterized in that it is performed at a temperature of 800 to 1000 ℃.

[0022] In addition, the present invention provides jewelry including a biological sample, which satisfies the following relationships (1) to (2).

[0023] (1) 30 ~ 100 Hv Vickers hardness

[0024] (2) Porosity of 30 to 80%

[0025] The present invention provides jewelry manufactured using a biological sample that can have a certain level or higher of mechanical strength by obtaining a combustion compound containing carbon and calcium phosphate from a human biological sample through a relatively simple and rapid process and mixing it with a solid containing silver, thereby providing a memory and a sense of psychological satisfaction by being able to be stored semi-permanently, and greatly enhancing the value as jewelry, thereby greatly improving consumer satisfaction.

[0036] Hereinafter, embodiments of the present invention will be described in detail so that those skilled in the art can easily implement the invention. The present invention may be implemented in various different forms and is not limited to the embodiments described herein.

[0037]

[0038] As described above, the conventional method of manufacturing jewelry using a biological sample, which is generally a part of the body, is disadvantageous in the commercial field due to the possibility of causing some disgust when using the biological sample as is, limitations in improving strength, difficulties in processing, limitations in improving strength, etc., making it difficult to increase the value as jewelry, and there are many technical difficulties in storing it for a long period of time in a place other than a laboratory with special conditions.

[0039] Accordingly, the present invention seeks to solve the above-described problem by providing a method for manufacturing jewelry including a biological sample, the method comprising a first step of obtaining a combustion compound including carbon and calcium phosphate from a biological sample, a second step of mixing the combustion compound and a solid including silver to obtain a paste, and a third step of sintering the paste manufactured by the second step.

[0040] Through this, the present invention can provide psychological satisfaction by making jewelry using a biological sample of a loved one through a relatively simple and quick process, making it a keepsake, and allowing it to be stored semi-permanently, and can maximize consumer preference by satisfying the value as jewelry.

[0041]

[0042] The present invention will be described in detail below.

[0043]

[0044] Jewelry manufacturing method

[0045] The first step of the method for manufacturing jewelry including a biological sample according to the present invention is a step of obtaining a combustion compound including carbon and calcium phosphate from the biological sample.

[0046] As mentioned above, processing biological samples such as hair, fingernails, toenails, teeth, and bones into jewelry can be repulsive to some people. In particular, methods that directly attach large quantities of biological samples to jewelry pose a risk of deterioration or decay due to the absorption or adsorption of moisture, foreign substances, or bacteria from the surrounding environment, resulting in the generation of an unpleasant odor or the biological sample itself being damaged by pests. To address these issues, methods have been disclosed that preservative biological samples such as hair before manufacturing them into jewelry. However, even in this manufacturing method, the shape of the biological sample is incorporated into the jewelry as is, making it unsuitable for everyday wear or use.

[0047] Accordingly, the present invention provides a method for manufacturing jewelry by combusting a biological sample to obtain a combustion compound containing carbon and calcium phosphate from the biological sample, and then mixing the obtained combustion compound with a solid containing silver. In order to obtain a combustion compound containing carbon and calcium phosphate from the biological sample, a biological extract must first be extracted from human body tissue or cremated ashes of a corpse. For example, the extracted biological sample may be at least one selected from the group consisting of human hair, fingernails, toenails, teeth, and bones.

[0048] More specifically, in order to obtain the first-stage combustion compound, any known conventional combustion method that is suitable for the purpose of the present invention may be employed, and is not particularly limited thereto. However, according to one embodiment of the present invention, a combustion compound may be obtained by combusting at least one or a mixture of human hair, fingernails, toenails, teeth, and bones, and pyrolysis may be performed in the following environment.

[0049] For example, the first step may be a thermal decomposition step at a temperature of 500 to 800°C for 20 to 40 minutes. At this time, if the temperature of the first step is lower than 500°C, the biological sample may not be sufficiently oxidized and organic residues containing carbon may remain, and there may be a problem that the high temperature must be maintained for more than 5 hours to remove them. In addition, if the temperature of the first step exceeds 800°C, only calcium phosphate may be obtained as a residue, but all carbon components may vaporize, and there may be a problem that the heat resistance and durability of the container for maintaining the high temperature must be strengthened.

[0050] Meanwhile, the method for obtaining the combustion compound of the first step is only an example of the present invention and is not limited thereto.

[0051]

[0052] Next, the second step of the method for manufacturing jewelry including a biological sample according to the present invention is a step of obtaining a paste by mixing the combustion compound and a solid containing silver.

[0053] Since the combustion compound obtained in the first step is not easily mixed into the precious metal molten metal, it must be mixed with a solid containing silver and sintered into a paste. In the case of the solid containing silver, any conventional solid containing silver known in the art can be used as long as it is suitable for the purpose of the present invention, and is not particularly limited thereto. However, according to one embodiment of the present invention, the solid containing silver is preferably formed by including a plate-shaped silver (Ag) powder, a binder resin, and an organic solvent, so as to have the utility of being able to be appropriately selected and used as a medium having a mechanical strength of a certain level or higher.

[0054] More preferably, in the case of the solid component containing silver, the silver particles may be contained at 64 to 89 wt%, the organic solvent at 10 to 30 wt%, and the glass powder at 1 to 6 wt% based on the total paste weight. At this time, when using the solid component containing silver, by using only spherical particles of uniform diameter, the formation of voids can be eliminated and continuity between particles can be more efficiently provided after the final sintering, thereby improving the mechanical properties. In addition, when the silver particles are less than 64 wt%, the amount of nano-sized silver particles is relatively small, which makes it difficult to maintain the appropriate strength required for jewelry during molding, making it difficult to achieve the intended effect of the present invention. When it exceeds 89 wt%, the nano-sized silver particles may self-agglomerate due to their high surface energy, making it difficult to uniformly mix the biological sample powder, which is not preferable.

[0055] In addition, according to one embodiment of the present invention, the combustion compound of the second step may be included in an amount of 1 to 6 wt%, and more preferably 2 to 3 wt%, based on the total paste weight. In this case, if the content of the combustion compound is less than 1 wt%, the final jewelry product of the present invention may contain too little biological sample, which may diminish the meaning of the present invention, or the hardness may be high, making it difficult to process into the intended jewelry product. In addition, if the content of the combustion compound exceeds 6 wt%, agglomeration may occur between the combustion compounds during the process of preparing the paste, which may make it difficult to maintain the shape during the molding process and cause destruction during sintering. In addition, it may affect the color of the final jewelry, resulting in a decrease in gloss and metallic color. In other words, when the combustion compound is included within the preferred numerical range of the present invention, the mechanical properties and gloss are the best.

[0056]

[0057] Next, the third step of the method for manufacturing jewelry including a biological sample according to the present invention is a step of sintering the paste manufactured by the second step.

[0058] In order to sinter the paste in the third step, any known conventional sintering method that is suitable for the purpose of the present invention may be employed, and is not particularly limited thereto. For example, when the paste is maintained at 900°C for 20 to 50 minutes, the binder inside the paste is vaporized and removed, and sintering progresses to a level where sufficient strength is achieved, thereby completing a sintered body.

[0059]

[0060] Jewelry

[0061] Next, a jewelry according to the present invention will be described. However, to avoid duplication, descriptions of parts that share the same manufacturing method and technical concepts as the jewelry described above will be omitted. The jewelry according to the present invention is jewelry containing a biological sample, comprising a combustion compound containing carbon and calcium phosphate, and a solid component containing silver.

[0062] As described above, the present invention provides a method for obtaining a combustion compound from a human biological sample through a relatively simple and rapid process, mixing it with a solid containing silver, and sintering the obtained mixture, thereby maintaining high mechanical strength while allowing semi-permanent storage, thereby providing psychological satisfaction and significantly increasing the value as jewelry. Accordingly, according to a preferred embodiment of the present invention, jewelry containing the combustion compound and the solid containing silver can satisfy all of the following relationships.

[0063] (1) 30 ~ 100 Hv Vickers hardness

[0064] (2) Porosity of 30 to 80%

[0065]

[0066] At this time, if the Vickers hardness of the above relationship (1) is less than 30 Hv, the probability of burrs occurring during jewelry manufacturing increases, and due to the soft nature, destruction may occur during use, making it difficult to increase the value as jewelry. In addition, if the Vickers hardness of the above relationship (1) exceeds 100 Hv, there may be problems with the cost of maintaining high temperatures and time during manufacturing because too little biological sample is mixed in and the sintering temperature is high. Accordingly, the Vickers hardness of 30 to 50 Hv is the most economical when considering the manufacturing time and manufacturing cost, and has an appropriate hardness when processing into jewelry such as necklaces or rings, which has an advantage in processing.

[0067] Meanwhile, if the porosity of the above relational expression (2) is less than 30%, the manufactured jewelry will have a high density, but there may be a problem in that the sintering conditions must be maintained at a high temperature for a long time to implement it. In addition, if it exceeds 80%, each pore becomes a path for cracks to be generated and propagated, which reduces the mechanical strength and causes problems in the durability of the jewelry to be worn. Accordingly, the porosity may be more preferably 50 to 60%, in which case the sintering time does not take long, which is advantageous in the manufacturing process and at the same time can improve the mechanical strength.

[0068] Hereinafter, the present invention will be described in more detail through examples, but the following examples do not limit the scope of the present invention, and should be interpreted as helping to understand the present invention.

[0069]

[0070] Example 1 - Manufacturing of Jewelry

[0071] To manufacture jewelry containing a biological sample, 40 g of the biological sample was combusted at a temperature of 600°C for 30 minutes, as shown in Fig. 1, to obtain a combustion compound containing carbon and calcium phosphate. The combustion compound thus obtained was mixed with 10 μm silver powder, 20 wt% of an organic solvent, and 3 wt% of glass powder to produce a paste weighing a total of 5 g.

[0072] The prepared mixture is placed in a dryer and dried at a temperature of 90℃ for 90 minutes, the dried mixture is sieved through a 1250 mesh sieve, and the sieved mixture is placed in a mold to produce 50 ton / in. 2 The molded product was molded under pressure, and the molded product was put into a sintering furnace, and sintered at a temperature of 900°C for 60 minutes while maintaining a vibration level of less than 500 microns to produce a solid component and an alloy composition including silver, and then a ring-shaped jewelry was produced using the alloy composition using a casting method.

[0073] The manufactured jewelry is shown in Fig. 4, and the weight percentage of the combustion compound relative to the total paste weight is as shown in Table 1 below. For comparison, a sintered body without the combustion compound was also made as a comparative example.

[0074]

[0075] Examples 2 to 3 - Manufacturing of jewelry

[0076] Jewelry was manufactured in the same manner as in Example 1 above, but the weight percentage of the combustion compound and the time were changed with respect to the total paste weight as shown in Table 1 below.

[0077] Classification Combustion compound (weight %) Sintering time Example 11.360 minutes Example 22.230 minutes Example 35.530 minutes Comparative example 0.30 minutes

[0078] Experimental Example 1 - Hardness Evaluation

[0079] For the above Examples 1 to 3 and Comparative Examples, hardness measurements were performed using MVK-H1, Akashi Corporation hardness tester, and the results are shown in Table 2 below.

[0080] Classification Vickers hardness (Hv) Example 151.82 Example 233.70 Example 325.22 Comparative example 53.30

[0081] Experimental Example 2 - Porosity Evaluation

[0082] For the above Examples 1 to 3 and Comparative Examples, the microstructure of the sample was photographed with an optical microscope (BX53M, OLYMPUS), and the image was magnified 100 times to enhance the contrast difference in the area of ​​the well-focused part, and the two-dimensional porosity expressed in white was calculated as (area of ​​porosity) / (total area)*100, and the porosity was evaluated as shown in Fig. 5, and the results are shown in Table 3 below.

[0083] Separation porosity (%) Example 140.4 Example 257.8 Example 379.2 Comparative example 38.0

[0084] Referring to Tables 1 to 3 above, among Examples 1 to 3 in which the weight % of the combustion compound with respect to the total paste weight satisfies the numerical range of the present invention, Example 2 is the most suitable in terms of processability and durability as jewelry based on the Vickers hardness and porosity test results. In particular, in the case of Example 3, since a relatively large amount of the combustion compound is included, it can be confirmed that this hinders the sintering of the silver powder and creates larger pore paths inside when the binder decomposes and escapes as gas, thereby increasing the porosity. In addition, in the case of Example 1, although the jewelry has a high density and excellent mechanical strength, it can be seen that the sintering conditions require a relatively high temperature that takes a long time, which is disadvantageous in terms of the manufacturing process.
