Description

  The present invention relates to an engraving stamp using Bincho charcoal as an engraving stamp material.

  Hoki is an art that was born in China since ancient times, but has been firmly established as a Japanese art since the Edo period. And since ancient times, there has been stone as a representative stamp. Many engravers make full use of these materials to express engraved art and have become established in people's lives.

  The conventional stone engraving stamps described above have various drawbacks. Stone engravings are all made in China, and the most commonly used ones are Yulin stone, Aoda stone, and Kotoyama stone. Since stones are natural products, the stones with the same name have different materials and hardness. And hardness is as low as about 3-10 degree | times, and its variation is also large. The price varies from pin to hole due to the difference in material and hardness (several hundred yen to several hundred thousand yen). The low-hardness one can easily lose the engraved marking surface due to a light impact (when it is accidentally dropped or hits the edge of a pottery-made mud container). Even if the materials are the same, the hardness varies one by one, and the hardness may vary even with a single marking surface, and there is a drawback that even a skilled person cannot easily discern it unless it is actually inserted. Engraving in accordance with the hardness of each type is a source of trouble as experienced by the engraver. In addition, the compatibility with stones changes depending on the sharpness of the sword, so the judgment of the sharpness of the sword depends on the experience of the engraver. The standard shape of the stone is a square or rectangle, so the character design must be contained within the frame. Therefore, the degree of freedom of the shape design is limited, and it is difficult to change. There is also a cone-shaped stone, but it is not practically preferable because it has a high probability of being slippery when it is stamped. In addition, stone powder scatters when carving stone with a sword. Care must be taken at all times as long-term inhalation of this powder will harm your health.

  In the present invention, such a conventional stone material has low hardness and large variation, so that it is easily chipped and has a drawback that the shape is limited to a standard shape of a square or a rectangle, and is scattered when engraved with a sword. It tries to solve the health problems caused by inhaling stone powder. On the other hand, Bincho charcoal has a hardness of 20 degrees, which is as hard as steel and has no variation, and is derived from natural wood that grows naturally, and its shape is diverse. By using this Bincho charcoal as a stamping material, there is no chipping of the engraved marking surface even if it is dropped or impacted on the edge of a pottery stamped mud (red meat) container, etc., and craft art using various shapes We can provide colorful engravings. Bincho charcoal is charcoal, so when carved with a sword, charcoal powder is scattered, but there is no health problem. Bincho charcoal, like ordinary charcoal, is easily soiled with charcoal powder on the surface of Bincho charcoal, but contains water or surfactant (cation, anion, nonionic surfactant). By washing the surface of Bincho charcoal with water, the hands will not get dirty. As mentioned above, it aims at providing Bincho charcoal which solved the fault of stone.

  In order to achieve the above object, the present invention uses Bincho charcoal as the engraved stamp material. Bincho charcoal is white charcoal. Currently, there are two types of Bincho charcoal, represented by white charcoal, which have raw wood from Ubmegashi and raw wood from Arakashi (in the future, Bincho charcoal will refer to the above two types). Neither of them has the same nature, but the way the trees grow is that the beaked snakes meander, whereas the arakashi is straight, both of which represent the characteristics of natural trees that grow naturally. Typical standards for the wood of Ubamegashi are Mameme-maru (round shape, diameter 1.5-2cm, length 20cm or more), Mameme-maru (round shape, diameter 2-3cm, length 20cm or more), horse There are upper small circles (round shape, 3-4 cm in diameter, 20 cm or more in length), and half round circles (round shape, 3-6 cm in diameter, 20 cm in length). Typical standards with Arakashi as raw wood include Sakai Hoshimaru (round shape, diameter 1 to 1.5 cm, length 20 cm or more) and Bincho Komaru (round shape, diameter 2 to 3 cm, length 20 cm or more). Bincho charcoal is mainly charcoalized around Tanabe City, Wakayama Prefecture, and it was said that it was completed by Genchuya Nagazaemon who lived there in Genroku years. The name Binchotan is said to have been created by Binya Yazaemon. Bincho charcoal is hard, its hardness is 20 degrees according to Miura type charcoal hardness meter, it is as hard as steel or more, it is hard to cut with saw, this kind of charcoal is not found in the world and it is unique to Japan. As described above, Bincho charcoal has a hardness of 20 degrees and is uniform with no variation in hardness. This hardness of 20 degrees can withstand impact when dropped or applied to the edge of a pottery seal mud (red meat) container and prevent chipping of the engraved marking surface. Binchotan is a natural tree that grows naturally. Various shapes and unique personalities can be provided. These Bincho charcoal are appropriately selected and used in accordance with the dimensions of the engraved engravings.

  As described above, Bincho charcoal has a hardness of 20 degrees, which is as hard as steel, and is uniform without variation. By using this Bincho charcoal as a stamping material, the stamped surface is resistant to impacts such as dropping and hitting the edges of pottery stamped mud (red meat) containers, and it will not be chipped under normal use. Mark can be provided. One of the advantages is that the cost is several hundred yen, which is cheap compared to stone.

  Next, the engraving method for Bincho charcoal stamp is described. The basic points of the engraving method are as follows. 1. The marking face of the Bincho charcoal cross section is flattened, and the circumference of the marking face is chamfered with a diamond file (with a radius of about 0.5 mm). 2. Apply the entire seal surface uniformly with red ink, and then write the characters to be carved in reverse with ink. 3. When engraving, always place a sword at a right angle to the radial grain on the marking surface. 4. The method of engraving performs engraving by properly using a sword and a pulling sword according to the place to be engraved. In this case, the sword should never be swung from side to side. The reason is to leave the trajectory accurately. 5. At first, it is shallow, and gradually engraves it repeatedly. 6. After engraving is completed, a transparent paint (varnish, etc.) is applied to the side of the printing material.

  When engraving on Bincho charcoal, it is not possible with conventional stone carving techniques. Binchotan's unique advanced engraving technology is required. At the time of engraving, stones have a low hardness, so the sword will bite into the marking surface and will not slide easily. Therefore, even if the angle of the sword is less than 45 ° at the maximum, even beginners can carve freely. On the other hand, Bincho charcoal has a hardness of 20 degrees, which is as hard as steel. As a countermeasure, it has been found that an angle of 50 to 60 ° with the sword raised is more optimal than that of stone. However, although engraving is possible even at angles other than 50 to 60 °, failures often occur and work becomes inefficient. Here, how to insert a stamp as a basic method of carving the Bincho charcoal stamp will be described with reference to FIGS. FIG. 1 shows the standard dimensions (unit: mm) and shape of the stamp. The front corner at the tip of the blade edge is a, and the opposite corner is b. Figure 2 shows how to sculpt with a sword. First, the stamp 1 is held in the right hand 2 and it is struck in small increments toward the front using the front edge a of the blade edge at an angle of 50-60 ° with respect to the long charcoal marking surface 3. Carve into. Fig. 3 shows how to engrave a pulling sword, so that the sword 1 is held in the right hand 2 and is drawn in small increments toward the front using the corner b on the side facing the blade edge of the sword at an angle of 50-60 ° with respect to the long charcoal marking surface 3. carve. The stamp should never be shaken from side to side. In the case of Bincho charcoal, there is a radial grain that is not found in stone. The point of technology is how to carve this grain. An example of this basic method of carving will be described in [0009].

  As an example, a basic engraving procedure for actually engraving a katakana character on the Bincho charcoal seal will be described with reference to FIGS. In FIG. 4, the entire surface of the marking surface 3 is flattened with a diamond file or sound paper. The periphery of the flat marking surface 3 is chamfered with a diamond file (chamfering with a radius of about 0.5 mm) 4. Next, red ink is applied evenly on the stamp surface 3. Next, the reverse 5 of the inscription W is written in black. Next, a vertical center line 7 and a horizontal center line 8 passing through the center point 6 of the stamp surface 3 are drawn with a pencil. Next, carve the outer vertical line 9 of the first stroke of the reverse character of the engraving. The arrow a indicates the direction and angle for inserting the stamp, and it is inserted at a right angle to the radial grain 10 of the stamp surface. The vertical line outside 9 of the 1st stroke of the reverse of the engraving wa is struck in small increments in the front direction (carved inward from the vertical line outside 9; the trajectory is indicated by small diagonal lines) with a sword according to the arrow a from bottom to top. Carve forward. Next, the inner side of the vertical line 11 is engraved from top to bottom with a pulling sword so as to be drawn in small steps in the forward direction (carved inward from the inner side of the vertical line 11; the locus is indicated by a small oblique line). Next, the vertical line bottom 12 is carved from right to left according to the arrow c so as to pierce with a sword in the front direction (carved inward from the vertical line bottom 12; the locus is indicated by small oblique lines). In Fig. 5, the upper part of the horizontal line 13 (right side of the vertical center line 7) of the reverse character of the engraved word is carved in the forward direction (inward from the upper part of the horizontal line 13) with a pulling sword according to the arrow D from the center to the right side. Carve it in small increments. Next, engrave the upper part of the horizontal line 14 (left side of the vertical center line 7) from the center to the left side in accordance with the arrow ho so that it is drawn in small steps in the forward direction (carved inward from the upper part of the vertical line 14). Proceed. Next, the lower part of the horizontal line 15 (on the right side of the vertical center line 7) is carved so that it is struck in small increments in the front direction (carved inward from the lower part of the horizontal line 15). Proceed. Next, the lower part of the horizontal line 16 (on the left side of the vertical center line 7) is carved so as to pierce in the direction from the left to the front according to the arrow with a sword in the front direction (inward from the lower part of the horizontal line 16). Proceed. In Fig. 6, the outer side 17 of the inversion of the engraved character (the upper side of the horizontal center line 8) is carved in the front direction (from the outer side of the curved line 17 to the inner side) with a sword from the center according to the arrow チ. Engrave so that it pierces in small increments. Next, the outer side of the curve 18 (below the horizontal center line 8) should be struck in small increments from the center to the front side (carved inward from the outer side of the curve 18. The locus is indicated by a small diagonal line) with a sword. Carve forward. Next, carve the inside 19 of the curve (upper side of the horizontal center line 8) from the top to the center according to the arrow and draw it in the direction of the front (carved inward from the curve 19). . Next, engrave the inside 20 of the curve (below the horizontal center line 8) from the bottom to the center according to the arrow and draw in small steps in the forward direction (carve inward from the inside 20 of the curve. The locus is indicated by small diagonal lines). Proceed. This completes the engraving of the engraved word. In FIG. 7, the portion 21 in the outline of the inverted character “W” is carved. According to the procedure described in FIG. 4 to FIG. 6, a sword and a pulling sword are used as appropriate. At first, the sword is shallow, and engraving is gradually repeated to deepen the engraving to complete the V-shaped inscription. In FIG. 4 to FIG. 7, the sword should never be swung from side to side. In FIG. 8, the state seen from the side surface engraved in the V shape is shown at 22.

  Binchotan charcoal is made from naturally grown natural wood. The shapes are diverse, and none of them are the same. The design of characters and pictures engraved on the stamp of the Bincho charcoal cross section will be unique. It is expected that the aesthetic expression will be infinitely spread by the synergistic effect of the unique shapes suitable for today in the 21st century and the design of the characters and pictures on the engraved seals.

  Because of the low hardness, which is a drawback of engraved stone materials, and the improvement of chipping caused by large variations, the strength of Bincho charcoal is 20 degrees, which is as hard as steel, and uniform with no variations Focused on that. In the case of Bincho charcoal, the hardness is as high as 20 degrees, and there is a radial grain that is not found in stone, so engraving technology corresponding to this has been a problem. The basic technology is as described in the paragraphs [0007], [0008] and [0009]. As a result, it is possible to provide engraved stamps that are resistant to impacts such as dropping and impacts such as hitting the edges of pottery-made mud (red meat) containers and that are not chipped under normal use.

The unique shape suitable for today in the 21st century and the design of the characters and pictures on the engraved seals are synergistic effects, and aesthetic expression can be expected to expand infinitely.

  On the other hand, stone powder scatters when carving engraved stone. Although there was a health problem by inhaling this powder for a long time, because Binchotan charcoal is charcoal, the charcoal powder is scattered when carved with a stamp, but there is no health concern at all. Bincho charcoal, like ordinary charcoal, is easily soiled with charcoal powder on the surface of Bincho charcoal, but water or surfactant (cation, anion, nonionic surfactant) ) By washing the surface of Bincho charcoal with water, it is possible to provide an engraved engraving that does not get dirty on the hands.

  Finally, the surface of Binchotan charcoal finished with engraving is coated with a transparent special paint (varnish, etc.), resulting in a gloss and improved product value, making it completely different from the stone engraving of stone. A sculpture elegance with artistic artistic value can be provided.

  By adjusting the state of the sticking of mud (red meat) on the surface of Binchotan charcoal, various changes that cannot be obtained with the stone stamping surface can be obtained, and various aesthetic expressions can be made depending on the hardness of the stamping floor. For example, it is possible to show Binchotan's wood grain by a second pressing method (paper placed on the dining table) with a second press (firstly, the stamping surface is filled with vermilion and pressed on the spare paper, and then lightly pressed).

  Bincho charcoal stamps are not limited to the functions of seals such as books and drawings, but can create value as decorations. A pendant with a crown that has a function to show the direction of the mark (a sign indicating the front), a brooch with a special fitting, a tie pin, etc., and a gemstone of a birthstone or a guard stone of a constellation It is possible to give value as a personal ornament that integrates accessories.

  Hereinafter, the embodiment of the present invention will be described based on FIG. 11 including the above-described drawings.

  In FIG. 9, 23 is a material of Bincho charcoal. Assuming a cross section corresponding to the character or picture to be engraved on the material 23 and cutting with a diamond cutter on the AA plane and the BB plane, three printing materials are formed. Using the middle stamping material 24, a katakana character is engraved. FIG. 10 shows the engraving stamp material 24. The AA surface is the upper end portion of the printing material, and the BB surface is the lower end portion. This lower end BB surface is used as a marking surface. First, the surface of the stamp 24 is washed with water (tap water). Next, the entire surface of the stamp 24 is polished with a diamond file or sound paper. Next, the marking surfaces 3 at the upper end (AA plane) and the lower end (BB plane) are flattened with a diamond file. In FIG. 11, the periphery 4 of the flat marking surface 3 is chamfered with a diamond file (a chamfer with a radius of about 0.5 mm). Next, red ink is evenly applied to the seal surface 3, and then the reverse character 5 of the engraving is written in black. Next, regarding the engraving procedure, the engraving is performed in accordance with the procedures described in FIGS. 4 to 7 in the items (0007), (0008), and (0009), and finished in a V shape. Complete. Fig. 11 shows the completion of Bincho charcoal stamp.
