[Technical Field]
[0001] The present invention relates to a method for producing keepsakes. [Background technology]
[0002] It has been known in the past that a body is placed in a crematorium together with a deceased pet or person, and what remains after cremation is used as a keepsake of the deceased pet or person. For example, Patent Document 1 discloses a cremation tool that is placed in a coffin together with the body and is made of a material that is heat-resistant above the combustion temperature during cremation.

[0003] [Patent Document 1] Registered Utility Model No. 3067469 Summary of the Invention [Problem to be solved by the invention]
[0004] However, the above-mentioned cremation equipment is designed to remain unburned and not deformed or melt during cremation. Therefore, after cremation, the same items remain unburned every time, and they do not become keepsakes that incorporate the feelings of the deceased pet or person.
[0005] To provide a method for producing keepsakes that can be made of different colors and patterns and that contain the feelings of deceased pets or the like. [Means for solving the problem]
[0006] One aspect of the present invention is a method for producing keepsakes, which includes a pre-cremation process in which the cremation object, which is a pet or a person, and the keepsake material, which is unglazed clay, are placed in a crematorium, and a cremation process in which the cremation object is crematized in the crematorium and the keepsake material is fired to produce a kiln-fired keepsake.
[0007] According to the above-mentioned keepsake manufacturing method, the pet or other cremated object is cremated together with the unglazed keepsake material during the cremation process. The pet or other cremated object burns to ash, which adheres to the unglazed keepsake material and acts as a glaze. Therefore, by firing the keepsake material, it is possible to create a keepsake with a color change or pattern, i.e., a kiln-changed keepsake.
[0008] Furthermore, the color changes and patterns that appear on keepsakes due to kiln changes are completely unpredictable, depending on the pet or other cremated object, including the influence of the atmosphere and temperature inside the crematorium. Therefore, it is possible to create keepsakes with different colors and patterns each time. This allows for a one-of-a-kind keepsake for the deceased pet, and each keepsake is imbued with the individual feelings of the deceased pet.
[0009] In the above-mentioned method for producing keepsakes, the keepsake material may be a bisque material made by bisque firing pottery clay. In this case, by firing the keepsake material, a kiln-changed keepsake can be easily produced.
[0010] The cremated remains may also be pets with fur. In this case, the ash produced by burning the pet's fur adheres to the unglazed ceramic keepsake material, effectively acting as a glaze. This makes it easy to create keepsakes with color changes and patterns (kiln-altered).
[0011] In addition, in the cremation process, the cremation temperature of the cremated object may be 800 to 1200 ° C. In this case, by firing the keepsake material together with the cremation of the cremated object, it is possible to easily create a kiln-changed keepsake.
[0012] Another aspect of the present invention, a method for producing keepsakes, includes a pre-cremation step in which the cremation object, which may be a pet or a person, and metal keepsake material are placed in a crematorium, and a cremation step in which the cremation object is cremate in the crematorium and a keepsake is made from the keepsake material.
[0013] According to the above-mentioned keepsake manufacturing method, the pet or other cremated object is cremated together with the metal keepsake material during the cremation process. The pet or other cremated object burns to ashes, which adhere to the surface of the metal keepsake material and undergo a chemical reaction with the metal keepsake material. This allows the creation of keepsakes with color changes or patterns on the surface.
[0014] Furthermore, the color changes and patterns that appear on the surface of the keepsake are completely unpredictable, depending on the pet or other cremated object, including the influence of the atmosphere and temperature inside the crematorium. Therefore, it is possible to create a keepsake with a different color and pattern each time. This allows for a one-of-a-kind keepsake of the deceased pet, which is imbued with the individual feelings of the deceased pet.
[0015] In the above-mentioned method for producing keepsakes, the keepsake material may be made of iron. In this case, the keepsake material can be easily produced without melting during the cremation process. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION
[0017] Hereinafter, an embodiment of the present invention will be described. (First embodiment) The keepsake manufacturing method of this embodiment is a method for producing a keepsake of a pet to be cremated during the process of cremating the deceased pet.
[0018] The method for producing keepsakes involves a pre-cremation process and a cremation process. In the pre-cremation process, as shown in Figures 1 and 2, the cremation subject 1 and keepsake material 2 are placed in a crematorium. The cremation subject 1 is a deceased pet (pet's remains). In this embodiment, a dog is used as the pet. The crematorium, not shown in the figure, is equipment for cremate the cremation subject 1. Any of various conventionally known crematoriums can be used.
[0019] The crematorium has a cremation table 31 made of fireproof concrete. The cremation table 31 can be carried into the crematorium using a dolly. The cremation table 31 has a recess 311 in the center. The top and inner wall surfaces of the recess 311 are provided with a ceramic fiber sheet 32, which is an inorganic fiber mainly composed of alumina (Al2O3) and silica (SiO2) and is 12.5 mm thick. In addition, multiple fireproof bricks 33 are provided within the recess 311.
[0020] A 20 mm thick wire mesh 34 is provided on the plurality of firebricks 33. A 12.5 mm thick ceramic fiber sheet 35 made of the same material as ceramic fiber sheet 32 is provided on wire mesh 34. A 5 mm thick wire mesh 36 is provided on ceramic fiber sheet 35. A nonwoven fabric 37 is provided on wire mesh 36 so as to cover wire mesh 36.
[0021] The cremated remains 1 are placed on the nonwoven fabric 37. Keepsake material 2 is also placed on the nonwoven fabric 37. The keepsake material 2 is placed on the nonwoven fabric 37 as close as possible to the cremated remains 1 so that it will change color during the cremation process described below.
[0022] The keepsake materials 2 are placed in the area A below or in front of the dog (the area opposite the back or the area far from the back) that is the cremation subject 1. In this embodiment, they are placed in the area A below the dog (the cremation subject 1). This is to prevent the dog (the cremation subject 1) from coming into contact with the keepsake materials 2 when the dog (the cremation subject 1) is cremated due to its arching back.
[0023] As shown in Fig. 3, the keepsake material 2 is a bisque material made by molding clay into a predetermined shape and then bisque firing it. Examples of clay that can be used as the raw material for the bisque material include pottery clay and clay for earthenware pots (clay containing petalite). In this embodiment, pottery clay is used.
[0024] Here, bisque firing refers to lightly firing the clay without applying a glaze at a relatively low temperature (for example, 700 to 800°C) in order to remove moisture contained in the clay base. The keepsake material 2 of this embodiment is a bisque fired material made from ceramic clay under the following conditions: the temperature is raised to 750°C over two hours, baked at 750°C for nine hours, and then slowly cooled over 24 to 36 hours.
[0025] The keepsake material 2 is configured in the shape of a square plate. In this embodiment, a biscuit material measuring 40 mm in length, 40 mm in width, and 10 mm in thickness is used as the keepsake material 2. The shape and size of the keepsake material 2 can be changed as appropriate.
[0026] In the pre-cremation process, the cremation table 31 on which the cremation subject 1 and keepsake materials 2 are placed as described above is carried into the cremation furnace using a cart. This allows the cremation subject 1 and keepsake materials 2 to be stored inside the cremation furnace.
[0027] Next, in the cremation process, the cremation subject 1 is cremated at a predetermined temperature (cremation temperature) in a crematorium, and the keepsake materials 2 stored together with the cremation subject 1 are also burned.
[0028] The cremation process is divided into a temperature increase process, a main cremation process, and a temperature decrease process. In the temperature increase process, the temperature inside the crematorium is increased from room temperature to the cremation temperature. In the main cremation process, the temperature inside the crematorium is maintained at the cremation temperature and the cremation object 1 is burned. In the temperature decrease process, the temperature inside the crematorium is decreased from the cremation temperature.
[0029] Specifically, in the temperature raising process, the temperature inside the crematorium is raised from room temperature to the cremation temperature in approximately 7 to 8 minutes using a burner installed in the crematorium. The cremation temperature can be adjusted depending on the type and size of the pet, which is the cremation subject 1. The cremation temperature can be set to, for example, 800 to 1200°C.
[0030] Next, in the cremation process, the temperature inside the crematorium is maintained at the cremation temperature, and the cremation subject 1 is burned. The time for maintaining the cremation temperature (cremation time) can be adjusted depending on the type and size of the pet that is the cremation subject 1. The cremation time can be, for example, 20 to 120 minutes.
[0031] At this time, the cremated object 1 burns to ash, and the ash adheres to the surface of the unglazed keepsake material 2. The ash (especially the ash from the body hair) that adheres to the surface of the keepsake material 2 acts as a glaze, so the keepsake material 2 is fired as the cremated object 1 burns, causing color changes and patterns on the surface of the keepsake material 2.
[0032] Next, in the temperature-lowering process, the temperature inside the crematorium is lowered from the cremation temperature to around 300°C in about 5 minutes, and then further lowered to around 100°C in 10 to 15 minutes. After that, the crematorium table 31 is carried out of the crematorium using a dolly.
[0033] This results in a kiln-changed keepsake 21 with color changes and patterns, as shown in Figure 4. The keepsake 21 may have an overall color change, or may have localized or partial color changes that appear as patterns (for example, kiln-changed part 22 shown in Figure 4).
[0034] Figure 5(A) is a photograph of keepsake material 2, which is a bisque material made by molding ceramic clay into a square plate and bisque firing it, and Figure 5(B) is a photograph of keepsake 21, which has been kiln-changed by firing keepsake material 2. As shown in Figures 5(A) and (B), it can be seen that by firing keepsake material 2, a keepsake 21 is obtained that has changed color and developed patterns (kiln-changed).
[0035] Next, the effects of the keepsake manufacturing method of this embodiment will be described. According to the keepsake manufacturing method of this embodiment, the cremation object 1, which is a deceased pet, is cremated together with the bisque-fired keepsake material 2 during the cremation process. The cremation object 1 burns to ash, and the ash adheres to the bisque-fired keepsake material 2, acting as a glaze. Therefore, by firing the keepsake material 2, a kiln-changed keepsake 21 can be produced, which has a change in color and a pattern.
[0036] Furthermore, the color changes and patterns that appear on the keepsake 21 due to kiln changes vary depending on the cremated object 1, including the influence of the atmosphere and temperature inside the crematorium during cremation, and are completely unpredictable. Therefore, it is possible to create a keepsake 21 with a different color and pattern each time. This allows for a one-of-a-kind keepsake 21 for the deceased pet, and the keepsake 21 is filled with even stronger memories of the deceased pet.
[0037] Furthermore, the keepsake material 2 is a bisque material made by firing clay. For example, if un-bisque fired clay or pottery or porcelain made by biscuit firing and final firing of clay is used, there is a risk of cracks and chips occurring during the cremation process. On the other hand, bisque fired materials can prevent such cracks and chips from occurring. Final firing refers to firing glazed clay at a higher temperature than bisque firing (for example, a temperature exceeding 1200°C).
[0038] In the keepsake manufacturing method of this embodiment, the keepsake material 2 is a bisque material made by bisque firing pottery clay. Therefore, by firing the keepsake material 2, a kiln-changed keepsake 21 can be easily produced.
[0039] The cremated object 1 is a pet (dog) with hair. The ash produced by burning the pet's hair adheres to the unglazed keepsake material 2, effectively acting as a glaze. This allows for the easy creation of keepsakes 21 with color changes and patterns (kiln-altered).
[0040] In addition, in the cremation process, the cremation temperature of the cremation subject 1 is 800 to 1200°C. Therefore, by firing the keepsake material 2 at the same time as the cremation of the cremation subject 1, it is possible to easily create a kiln-changed keepsake 21.
[0041] (Second embodiment) 6 to 9, this embodiment is an example in which the shape, configuration, etc. of the keepsake material 2 are changed. Note that a description of the same configuration and effects as those of the first embodiment will be omitted.
[0042] As shown in Figures 6 and 7, the keepsake material 2 placed in the crematorium together with the cremated body 1 during the pre-cremation process is a rectangular plate with a recessed center 20. An additional material 4 is placed in the recess 20 of the keepsake material 2.
[0043] The additional material 4 is made of spherical glass. In this embodiment, a marble with a diameter of 12.5 mm is used as the additional material 4. The size of the additional material 4 can be changed as appropriate.
[0044] The material of the additional material 4 is silicate glass whose main component is silicon dioxide (silica: SiO2). The melting temperature (melting point) of the additional material 4 is lower than the cremation temperature at which the cremation target 1 is cremated in the cremation process described below. In this embodiment, the melting temperature of the additional material 4 is 700 to 800°C.
[0045] In the cremation process, the cremated object 1 is cremated at a predetermined temperature (cremation temperature) in a crematorium, and the keepsake material 2 stored together with the cremated object 1 is fired. At this time, the additional material 4 is melted and cooled within the recess 20 of the keepsake material 2, causing it to deform. By melting the additional material 4 within the recess 20 of the keepsake material 2, the molten additional material 4 can be prevented from flowing out of the keepsake material 2.
[0046] As a result, a keepsake 21 is obtained that has undergone color changes and patterns (kiln-fired), as shown in Figures 8 and 9. The additional material 4 is formed in the recess 20 of the keepsake 21 so as to fill the recess 20 and prevent it from falling out of the recess 20. In other words, the additional material 4 is fixed in the recess 20 of the keepsake 21.
[0047] 10 is a photograph showing a partial cross section of a keepsake 21 that has been kiln-changed by firing the keepsake material 2. As shown in FIG. 10, by firing the keepsake material 2 with the additional material 4 placed in the recess 20, the additional material 4 is melted and cooled in the recess 20, and a keepsake 21 with the additional material 4 fixed in the recess 20 is obtained.
[0048] According to the keepsake manufacturing method of this embodiment, it is possible to produce a keepsake 21 with a change in color or pattern (kiln-fired), and to form an additional material 4 in the recess 20 of the keepsake 21. In other words, a keepsake 21 with an additional material 4 fixed therein is obtained. The additional material 4 also varies depending on the cremated object 1, including the influence of the atmosphere and temperature in the crematorium during cremation. As a result, a one-of-a-kind keepsake 21 is obtained for the deceased pet, and the keepsake 21 is imbued with even stronger feelings about the deceased pet.
[0049] (Third embodiment) 11(A) and (B), this embodiment is an example in which the material constituting the keepsake material 2 is changed. Note that a description of the same configuration and effects as those of the first embodiment will be omitted.
[0050] FIG. 11(A) is a photograph of the keepsake material 2. As shown in the figure, the keepsake material 2 is made of metal. Examples of metals that can be used to make the keepsake material 2 include iron, copper, nickel, titanium, and platinum. It is also preferable to use a metal with a melting point higher than the cremation temperature. The keepsake material 2 of this embodiment is made of iron. The keepsake material 2 is an L-shaped metal piece. The shape and size of the keepsake material 2 can be changed as needed.
[0051] After the pre-cremation process, in the cremation process, the cremation subject 1 is cremated in a crematorium at a predetermined temperature (cremation temperature), and a keepsake 21 (see Figure 11(B) below) is made from the keepsake material 2 stored together with the cremation subject 1.
[0052] Figure 11(B) is a photograph of the keepsake 21 made from the keepsake material 2. As shown in the figure, the keepsake 21 has a change in surface color and a pattern. This is thought to be because the cremated object 1 burns and turns to ash, which adheres to the surface of the keepsake material 2, and the ash (especially the ash from the body hair) reacts chemically with the keepsake material 2.
[0053] According to the keepsake manufacturing method of this embodiment, during the cremation process, the cremation object 1, which is a deceased pet, is cremated together with the metal keepsake material 2. During this process, the cremation object 1 is burned to ashes, and the ashes adhere to the surface of the metal keepsake material 2, causing a chemical reaction between the metal keepsake material 2 and the cremation object 1. This allows for the creation of a keepsake 21 with a color change or pattern on the surface.
[0054] Furthermore, the color changes and patterns that appear on the surface of the keepsake 21 are completely unpredictable, and vary depending on the cremated object 1, including the influence of the atmosphere and temperature inside the crematorium. Therefore, it is possible to create keepsakes with different colors and patterns each time. This allows for a one-of-a-kind keepsake 21 for the deceased pet, and the keepsake 21 is imbued with even stronger feelings about the deceased pet.
[0055] In the method for producing keepsakes according to this embodiment, the keepsake material 2 is made of iron. Therefore, during the cremation process, the keepsake material 2 does not melt when the cremated object 1 is cremated, and the keepsake 21 can be easily produced.
[0056] (Other embodiments) The present invention is not limited to the above-described embodiment, and it goes without saying that the present invention can be embodied in various forms without departing from the scope of the present invention.
[0057] (1) In the above embodiment, the cremation subject 1 was a pet, but the cremation subject may also be a person. Also, while a dog was used as an example of a pet that is the cremation subject 1, pets may be any animal kept by a person, such as a dog, cat, small animal (rabbit, mouse, bird, etc.), insect, etc. Pets with a lot of hair are more likely to produce mementos with color changes and patterns, making it easier to obtain mementos that have been kiln-altered.
[0058] (2) In the above embodiments (first and second embodiments), the keepsake material 2 is a square plate, but the shape of the keepsake material may be any shape that can be molded from clay, and the keepsake material may have various shapes, such as a sphere. Furthermore, by forming the keepsake material into the shape of an urn for storing ashes or a figurine, the keepsake can be used as an urn or a figurine.
[0059] (3) In the above embodiment (second embodiment), the material constituting the additional material 4 is glass, but the material constituting the additional material may also be metal. In this case, it is preferable to use a metal whose melting temperature (melting point) is lower than the cremation temperature, and for example, aluminum, tin, lead, etc. can be used.
[0060] (4) In the above embodiment (second embodiment), the keepsake material 2 has a recess 20 as a portion where the additional material 4 is melted, cooled, and fixed, but the portion where the additional material is fixed may have any configuration. Furthermore, the additional material or the portion where the additional material is fixed may be one or more.
[0061] (5) The function of one component in the above embodiments may be distributed among multiple components, or the functions of multiple components may be integrated into one component. Also, part of the configuration of the above embodiments may be omitted. Furthermore, at least part of the configuration of the above embodiments may be added to or substituted for the configuration of another of the above embodiments.
