[Effects of the Invention]

[0010] Next, the effects of the present invention will be described with reference to the reference numerals in the drawings. Note that the reference numerals in parentheses are those of embodiments described later, but the present invention is not limited thereto.

[0011] According to the invention of claim 1, along the damaged portions (2b, 3b) of the first fragment (2) and the second fragment (3) To that end, a sealing member (laminate seal 5) is attached to the inner surfaces of the first fragment (2) and the second fragment (3), In the damaged portions (2b, 3b) of the first fragment (2) and the second fragment (3), the portion corresponding to the edge (1a) of the ceramic (1) is attached to the inner surface (2a, 3a) of the first fragment (2) and the second fragment (3) in a state of outward protrusion, and a sealing member (laminate seal 5) is attached. Then, epoxy resin clay (6) is applied to the damaged portions (2b, 3b) of the first fragment (2) and the second fragment (3), and the damaged portion (2b) of the first fragment (2) and the damaged portion (3b) of the second fragment (3) are combined. After that, A different sealing member (masking tape 7) is attached to the inner and outer surfaces (inner surface 2a, outer surface 2c, inner surface 3a, outer surface 3c) of the first fragment (2) and the second fragment (3) so as to connect them. Then, the different sealing member (masking tape 7) attached to the inner and outer surfaces (inner surface 2a, outer surface 2c, inner surface 3a, outer surface 3c) of the first fragment (2) and the second fragment (3) is peeled off. The repair process is simple and easy, as it only involves following these steps: 1. Apply a sealing member (laminate seal 5) to the outer surfaces (outer surfaces 2c, 3c) of the first fragment (2) and the second fragment (3), following the damaged areas (2b, 3b) of the first fragment (2) and the second fragment (3). 2.

[Modes for carrying out the invention]

[0016] Hereinafter, a pottery restoration method according to an embodiment of the present invention will be specifically described with reference to the drawings. In the following description, when indicating the directions of up, down, left, and right, it refers to up, down, left, and right as viewed from the front shown in the drawings.

[0017] The pottery restoration method according to this embodiment is simple and easy, and can restore damaged pottery like a metal joint. Specifically, it will be restored through the steps shown in FIG. 1. In this regard, mainly taking the steps shown in FIG. 1, it will be described in detail below.

[0018] First, for example, prepare a pottery 1 made of a bowl-shaped vessel as shown in FIG. 2 (step S1). As shown in FIG. 2, this pottery 1 is composed of a first fragment 2 with a part of the pottery 1 damaged, a second fragment 3 having a substantially triangular shape, and a third fragment 4 having a substantially triangular shape.

[0019] Next, as shown in FIGS. 3 and 4, attach a laminate seal 5 to the inner surface 2a of the first fragment 2, the inner surface 3a of the second fragment 3, and the inner surface 4a of the third fragment 4 shown in FIG. 2 (step S2). Note that as methods for attaching the laminate seal 5, there are a method of surface attachment and a method of line attachment, and either one of the methods may be used. In this embodiment, an example using both methods will be described.

[0020] As shown in Figure 3(a), a rectangular laminate seal 5 is attached to the entire surface of the inner surface 3a of the second fragment 3. In other words, surface application is performed. Then, as shown in Figure 3(b), an art knife AN or the like is used to cut off the excess portion of the laminate seal 5 along the damaged part 3b of the second fragment 3 (see also Figure 2). Of the laminate seal 5 attached to the inner surface 3a of the second fragment 3 as shown in Figure 3(a), it is preferable to attach the portion of the laminate seal 5 corresponding to the edge 1a of the ceramic 1 shown in Figure 2 so that it protrudes slightly. This portion corresponding to the edge 1a of the ceramic 1 is a place that people tend to touch. Touching it will reduce the adhesive strength of the laminate seal 5, so it is better to attach it so that it protrudes slightly, taking into account the thickness of the ceramic 1, so that the reduced adhesive strength does not cause problems. Therefore, it is preferable that the laminate seal 5 on the part corresponding to the edge 1a of the ceramic 1 shown in Figure 2 be attached in a state where it protrudes slightly.

[0021] On the other hand, as shown in Figure 4, a linear laminate seal 5, for example, 5 mm wide, is attached to the inner surface 4a of the third fragment 4 along the damaged portion 4b of the third fragment 4 (see Figure 4(b)). In other words, linear application is performed. As described above, of the laminate seal 5 attached to the inner surface 4a of the third fragment 4 shown in Figure 4(b), it is preferable that the portion of the laminate seal 5 corresponding to the edge 1a of the ceramic 1 shown in Figure 2 is attached in a state where it protrudes slightly.

[0022] On the other hand, although not shown in the illustration, the first fragment 2 shown in Figure 2 is also fitted with a linear laminate seal 5, for example, 5 mm wide, along the damaged portion 2b of the first fragment 2 (see Figure 2). In other words, the seal is applied in a linear manner. In this case, as with the above, it is preferable that the laminate seal 5 corresponding to the edge 1a of the ceramic 1 is applied in a state where it protrudes slightly.

[0023] Next, the first fragment 2, the second fragment 3, and the third fragment 4, to which the laminate seal 5 has been attached as described above, are sanded (step S3). Specifically, this is done as follows.

[0024] Using the third fragment 4 as an example, first, as shown in Figure 5(a), the corner of the damaged portion 4b on the inner surface 4a side of the third fragment 4 is filed using a file YS. At this time, since the laminate seal 5 is attached to the inner surface 4a side of the third fragment 4, the file is filed in one direction from vertically upward to downward to avoid peeling it off. This removes the excess portion of the laminate seal 5.

[0025] Next, as shown in Figure 5(b), the corner portion of the damaged part 4b on the outer surface 4c side of the third fragment 4 is filed using a file YS.

[0026] Thus, by filing the corner of the damaged portion 4b of the third fragment 4 (see also Figure 2) in this manner, minute irregularities (roughness) are created on the damaged portion 4b of the third fragment 4 (see also Figure 2), and the epoxy resin clay 6 (see Figures 6(a) and (b) described later) adheres to these minute irregularities. This allows the damaged portion 2b of the first fragment 2, the damaged portion 3b of the second fragment 3, and the damaged portion 4b of the third fragment 4 to be firmly fixed together. After filing the corner as described above, the damaged portion 4b of the third fragment 4 (see also Figure 2) should be wiped clean with an alcohol-based wet wipe. Although not shown in the illustration, the damaged portion 2b of the first fragment 2 and the damaged portion 3b of the second fragment 3 shown in Figure 2 should also be filed in the same manner as described above, and after filing the corner, they should be wiped with an alcohol-based wet wipe.

[0027] Although not shown in the diagram, the first fragment 2 and the second fragment 3 are also filed down in the same manner as described above.

[0028] Next, after sanding as described above, epoxy resin clay 6 (for example, wGlue®) as shown in Figures 6(a) and (b) is applied to the damaged portion 2b of the first fragment 2, the damaged portion 3b of the second fragment 3, and the damaged portion 4b of the third fragment 4, and the pieces are assembled to form the ceramic 1 (Step S4). Specifically, this is done as follows.

[0029] To explain using the third fragment 4 as an example, as shown in Figure 6(a), epoxy resin clay 6 is applied to the damaged portion 4b using a bamboo spatula TB or the like. At this time, the epoxy resin clay 6 should be applied thinly. If it is applied thickly, the minute irregularities of the damaged portion 4b of the third fragment 4, the minute irregularities of the damaged portion 2b of the first fragment 2, and / or the minute irregularities of the damaged portion 3b of the second fragment 3 may not fit together.

[0030] Thus, epoxy resin clay 6 is applied to the damaged portion 2b of the first fragment 2, the damaged portion 3b of the second fragment 3, and the damaged portion 4b of the third fragment 4, to the state shown in Figure 6(b). Then, the damaged portion 2b of the first fragment 2, the damaged portion 3b of the second fragment 3, and the damaged portion 4b of the third fragment 4 are combined to assemble the ceramic 1 as shown in Figure 6(c). As shown in Figure 8(c), a laminate seal 5 is attached to the inner surface 2a of the first fragment 2, along the damaged portion 2b of the first fragment 2 (see Figure 2); a laminate seal 5 is attached to the inner surface 3a of the second fragment 3, along the damaged portion 3b of the second fragment 3 (see Figure 2); and a laminate seal 5 is attached to the inner surface 4a of the third fragment 4, along the damaged portion 4b of the third fragment 4 (see Figure 2). As a result, when the ceramic 1 is assembled, a gap K1 is formed between the laminate seal 5 attached to the inner surface 2a of the first fragment 2, the laminate seal 5 attached to the inner surface 3a of the second fragment 3, and the laminate seal 5 attached to the inner surface 4a of the third fragment 4, as shown in Figure 8(c).

[0031] Next, masking tape is applied to the assembled ceramic piece 1 to fix the combined positions of the damaged portion 2b of the first fragment 2, the damaged portion 3b of the second fragment 3, and the damaged portion 4b of the third fragment 4 (step S5). Specifically, this is done as follows.

[0032] First, as shown in Figure 7(a), a rectangular masking tape 7 is attached to the outer surface of the assembled ceramic 1, that is, the outer surface 2c of the first fragment 2, the outer surface 3c of the second fragment 3, and the outer surface 4c of the third fragment 4, connecting the outer surface 2c of the first fragment 2, the outer surface 3c of the second fragment 3, and the outer surface 4c of the third fragment 4. This fixes the combined position of the damaged portion 2b of the first fragment 2, the damaged portion 3b of the second fragment 3, and the damaged portion 4b of the third fragment 4. In this state, the inner surface of the assembled ceramic 1 is cleaned with an alcohol-containing wet wipe or the like to make the inner surface of the assembled ceramic 1 clean.

[0033] Then, as shown in Figure 7(b), a rectangular masking tape 7 is attached to the inner surface of the ceramic 1, that is, the inner surface 2a of the first fragment 2, the inner surface 3a of the second fragment 3, and the inner surface 4a of the third fragment 4, connecting the inner surface 2a of the first fragment 2, the inner surface 3a of the second fragment 3, and the inner surface 4a of the third fragment 4. This fixes the combined position of the damaged portion 2b of the first fragment 2, the damaged portion 3b of the second fragment 3, and the damaged portion 4b of the third fragment 4. In this state, the masking tape 7 shown in Figure 7(a) is peeled off, and the outer surface of the assembled ceramic 1 is cleaned with an alcohol-containing wet wipe or the like to make the outer surface of the assembled ceramic 1 clean. Then, as shown in Figure 7(a), the masking tape 7 is attached to the outer surface of the assembled ceramic 1 again. This allows the combined positions of the damaged portion 2b of the first fragment 2, the damaged portion 3b of the second fragment 3, and the damaged portion 4b of the third fragment 4 to be firmly fixed.

[0034] Next, as shown in Figure 7, the assembled ceramic 1, with masking tape 7 attached to its inner and outer surfaces, is placed in a towel warmer (not shown) for approximately 30 minutes to promote the hardening of the epoxy resin clay 6. After that, all of the masking tape 7 shown in Figure 7 is removed (step S6).

[0035] Next, a laminate seal 5 is attached to the outer surface of the assembled ceramic 1 (step S7). Specifically, this is done as follows.

[0036] As shown in Figure 8(a), laminate seals 5 are attached to the outer surfaces of the ceramic 1, that is, the outer surface 2c of the first fragment 2, the outer surface 3c of the second fragment 3, and the outer surface 4c of the third fragment 4. More specifically, as shown in Figure 8(a), a linear laminate seal 5 is attached to the outer surface 2c of the first fragment 2, following the damaged portion 2b of the first fragment 2 (see Figure 2). Furthermore, as shown in Figure 8(a), a linear laminate seal 5 is attached to the outer surface 3c of the second fragment 3, following the damaged portion 3b of the second fragment 3 (see Figure 2). And then, as shown in Figure 8(a), a linear laminate seal 5 is attached to the outer surface 4c of the third fragment 4, following the damaged portion 4b of the third fragment 4 (see Figure 2). As a result, as shown in Figure 8(a), a gap K2 is formed between the laminate seal 5 attached to the outer surface 2c of the first fragment 2, the laminate seal 5 attached to the outer surface 3c of the second fragment 3, and the laminate seal 5 attached to the outer surface 4c of the third fragment 4.

[0037] Next, epoxy resin clay 6 is applied to fill the gaps K1 shown in Figure 8(c) and K2 shown in Figure 8(b) (Step S8). Specifically, this is done as follows.

[0038] First, epoxy resin clay 6 is applied to fill the gap K1 shown in Figure 8(c), and then epoxy resin clay 6 is applied to fill the gap K2 shown in Figure 8(b). Furthermore, as shown in Figures 8(b) and (c), epoxy resin clay 6 is applied to fill the gaps K1 and K2 formed on the edge 1a of the ceramic 1. In this way, epoxy resin clay 6 is applied to fill all the gaps K1 and K2.

[0039] Next, the laminate seals 5 attached to the outer and inner surfaces of the ceramic 1 described above are completely removed using tweezers PN or the like, as shown in Figure 9(a) (step S9). This creates a beautiful line L1 of epoxy resin clay 6 on the damaged part of the ceramic 1, as if it were repaired with kintsugi, as shown in Figure 9(b). If the line L1 of epoxy resin clay 6 shown in Figure 9(b) is interrupted, place it in a towel warmer (not shown) for about 45 minutes to accelerate the hardening of the epoxy resin clay 6. After that, proceed with steps S7 to S9 shown in Figure 1.

[0040] Next, the line L1 of the epoxy resin clay 6 shown in Figure 9(b) is smoothed using a spatula or similar tool (not shown), and allowed to harden naturally for 24 hours (step S10). This completes the restoration work on the ceramic 1.

[0041] According to the embodiment described above, epoxy resin clay 6 is applied to the damaged portion 2b of the first fragment 2, the damaged portion 3b of the second fragment 3, and the damaged portion 4b of the third fragment 4, and then the ceramic 1 is assembled as shown in Figure 6(c). Meanwhile, laminate seal 5 is attached so that gaps K1 and K2 are formed, epoxy resin clay 6 is applied to fill the gaps K1 and K2, and then the laminate seal 5 is peeled off. The repair work can be done simply by performing these steps, making it easy and straightforward. Moreover, as shown in Figure 9(b), a beautiful line L1 of epoxy resin clay 6 is created on the damaged part of the ceramic 1, as if it were kintsugi (gold repair).

[0042] Therefore, according to this embodiment, it is possible to repair damaged pottery 1 in a simple and easy manner, similar to the kintsugi method.

[0043] <Explanation of variations> It should be noted that the shapes and other details shown in this embodiment are merely examples, and various modifications and changes are possible within the scope of the gist of the present invention as described in the claims. For example, in this embodiment, an example is shown in which the laminate seal 5 is attached to the inner surface 2a of the first fragment 2, the inner surface 3a of the second fragment 3, and the inner surface 4a of the third fragment 4 before assembling the ceramic 1 as shown in Figure 6(c). However, it is not limited to this, and the laminate seal 5 may also be attached to the inner surface 2a of the first fragment 2, the inner surface 3a of the second fragment 3, and the inner surface 4a of the third fragment 4 after assembling the ceramic 1 as shown in Figure 6(c). Nevertheless, it is preferable to attach the laminate seal 5 to the inner surface 2a of the first fragment 2, the inner surface 3a of the second fragment 3, and the inner surface 4a of the third fragment 4 before assembling the ceramic 1 as shown in Figure 6(c). If the ceramic 1 is assembled as shown in Figure 6(c), it becomes very difficult to attach the laminate seal 5 to the inner surface 2a of the first fragment 2, the inner surface 3a of the second fragment 3, and the inner surface 4a of the third fragment 4. This makes it impossible to create a clean line L1 of epoxy resin clay 6 on the damaged part of the ceramic 1, as shown in Figure 9(b), which resembles kintsugi (gold repair).

[0044] Furthermore, although this embodiment shows an example using laminate seal 5, it is not limited to this; any sealing member can be used as long as it can perform the same function as laminate seal 5.

[0045] Furthermore, in this embodiment, masking tape 7 was used to fix the position of the assembled ceramic 1, but the invention is not limited to this; any sealing material that can perform the same function as masking tape 7 may be used.

[0046] Furthermore, although this embodiment shows an example with a first fragment 2, a second fragment 3, and a third fragment 4, it is of course applicable to two fragments, and also to four or more fragments. In other words, it is applicable as long as there are at least two fragments. [Explanation of Symbols]
