Description

Technical Field

[0001] This invention belongs to the field of arts and crafts technology, and relates to a method for embedding gold in Helan inkstones and a manual grooving tool. Background Technology

[0002] Mohs hardness is a standard for expressing the hardness of minerals. Jade can be divided into two main categories: jadeite and nephrite. Jadeite, represented by jade, has a hardness between 6.5 and 7. Nephrite, represented by Hetian jade, has a hardness between 6.0 and 6.5.

[0003] The hardness of inkstones generally ranges from 2.5 to 4.0. Although there is only a 2-degree difference in hardness between the two, their strength and wear resistance are vastly different, almost like heaven and earth. Diamond is the hardest mineral with a hardness of 10, while sapphire and ruby ​​have a hardness of 9. However, a diamond with a hardness of 10 is 140 times harder than a sapphire with a hardness of 9.

[0004] Inkstone is a material commonly used in the making of inkstones. It has a certain degree of hardness and is easy to carve. At the same time, inkstone also has the characteristics of low density and loose structure of crystal particles at the micro level. This makes it difficult to carry out fine carving or inlaying. In other words, there is no precedent for inlaying gold on inkstones. Summary of the Invention

[0005] The purpose of this invention is to provide a method for embedding gold in Helan inkstones, which involves pressing gold into the relatively brittle Helan inkstones to enrich and enhance the artistic expression of inkstone carving.

[0006] The present invention also aims to provide a manual grooving tool, specifically designed for the refined operation of grooving on the surface of Helan inkstones.

[0007] The technical solution of the present invention to solve the above-mentioned technical problems is as follows.

[0008] A method for embedding gold in Helan inkstones includes the following steps:

[0009] (1) Grooving of Helan inkstone: Grooves are cut on the surface of Helan inkstone, and the cross-sectional shape of the groove is trapezoidal;

[0010] (2) Selection of gold wire: The purity of gold used in gold wire is above 80%;

[0011] (3) Place the gold wire and press down: After placing the gold wire in the groove, press down. The pressing force increases with the increase of the groove width.

[0012] (4) Hammering and compacting: Hammering the surface of the Helan inkstone on which the gold thread is placed;

[0013] (5) Grouting and stabilization: Apply adhesive evenly to the working surface of the Helan inkstone with embedded gold wire at room temperature and let it dry at room temperature;

[0014] (6) Trimming and polishing: Remove and trim the gold material that is higher than the groove opening.

[0015] Furthermore, in step (1) of this method, the width a of the groove is 0.1mm~2mm, the depth b of the groove is a+(0.1mm~0.3mm), and the apex angle β of the groove is 100°~110°.

[0016] Furthermore, in step (2) of this method, the diameter r of the gold wire is a + (0.2 mm ~ 0.4 mm).

[0017] Furthermore, in step (3) of this method, for the case where the purity of gold is above 99.99%, when the groove width is between 0.1mm and 0.7mm, the downward pressure is between 0.3kg and 3.0kg; when the groove width increases by 0.1mm from 0.7mm, the downward pressure increases by 1.5kg accordingly; when the purity of gold decreases by 5% from 99.99%, the downward pressure increases by 8% accordingly; the distance of each downward push is controlled between 0.3mm and 1mm.

[0018] Furthermore, in step (4) of this method, for gold with a purity of 99% or higher, the impact pressure of each hammering is 0.2 kg to 0.4 kg, and the impact area is less than 2 mm. 2 When the gold purity is higher than 80% but lower than 99%, the impact pressure of hammering increases by 20% and the impact area decreases by 50%.

[0019] Furthermore, in step (5) of this method, a resin-based adhesive or natural liquid shellac is evenly brushed onto the working surface of the Helan inkstone with embedded gold wire at room temperature and left to dry at room temperature for 48 hours.

[0020] Furthermore, in step (6) of this method, the trimming requires a flat or beveled tool with a cutting edge engagement angle of 5°~10°; each time the tool is pushed and scraped, the thickness is ≤ 0.1mm; the polishing requires 1000-7000 grit wet sandpaper with water added in sequence.

[0021] A manual grooving tool includes a cutting head, a handle, and a direction indicator plate connected in sequence; the cutting edge plane at the end of the cutting head is trapezoidal, and the direction indicator plate is a trapezoidal plate structure, with its plate plane parallel to the cutting edge plane at the end of the cutting head; the trapezoid of the direction indicator plate is a proportionally enlarged version of the trapezoid of the cutting edge of the cutting head, and its direction is approximately 90° rotated around the axis of the handle; the cutting edge width of the cutting head is 0.1mm~2mm.

[0022] Furthermore, this hand-grooving tool is used for fine processing, grooving the surface of Helan inkstone, with a groove width a of 0.1mm~2mm and a groove depth b of a+(0.1mm~0.3mm).

[0023] Furthermore, the process of using this manual grooving tool to groove the surface of Helan inkstone is as follows: (1) Cut at a right angle, with a cutting depth ≤0.1mm and a cutting distance ≤3mm each time, and repeat in sequence; (2) After reaching the required depth, the blade angle is used to expand the bottom along the two bottom edges at 120-degree and 60-degree angles.

[0024] The beneficial effects of the method for embedding gold in Helan inkstones and the hand-grooving tool of this invention are as follows: By pressing gold into the relatively brittle Helan inkstone, the inkstone carving, which originally had a single color tone, gains a richer and more vivid expressiveness, and the derivative and expressive forms of artistic expression are stronger, enriching and increasing the expressive forms of inkstone carving art. It can be widely used in inkstone carving art. Using the hand-grooving tool with a direction indicator plate, the correct cutting angle can be adjusted and determined at any time. The blade angle is parallel to the direction indicator plate, which can indicate the blade angle. It is specially used for the fine operation of grooving on the surface of Helan inkstones.

[0032] The hardness of Helan inkstones is between 3 and 3.5, which is the highest among inkstones. They are easy to grind ink on and do not damage the brush. Therefore, Helan inkstones are most suitable for gold inlay. This technique also uses Ningxia Helan inkstones as the inkstone material to inlay gold on Helan inkstones. To achieve the same artistic effect as inlaying gold on metal or jade, a completely new and precise standard technique is required, which is different from the gold inlaying on metal or jade.

[0033] Example 1

[0034] A method for embedding gold in Helan inkstones, characterized by comprising the following steps.

[0035] (1) Grooving of Helan Inkstone: Groove 2 is cut on the surface of Helan Inkstone 1. The cross-sectional shape of groove 2 is trapezoidal; such as Figure 1 As shown, when grooving various Helan inkstones, the width 'a' of the groove opening is 0.1mm~2mm, and the depth 'b' of the groove must be greater than the width 'a' of the groove opening. Specifically, 'b' is a + (0.1mm~0.3mm), meaning that the depth of the groove must be greater than the width of the groove opening by 0.1mm~0.3mm. The apex angle 'β' of the groove is 100°~110°, meaning that the width of the groove bottom should be controlled within a 10° to 20° offset from the width of the groove opening. Exceeding this range will cause the groove opening to crack during the later gold-pressing process.

[0036] (2) Selection of gold wire: The purity of gold used in the gold wire is above 80%; the diameter r of the gold wire is a+ (0.2mm~0.4mm). That is to say, the diameter of the gold wire should be greater than the width of the groove, and the range should be controlled between 0.2mm and 0.4mm. If it is greater than this control range, the groove will collapse and crack, thus damaging the whole.

[0037] (3) Place the gold wire and press down: After placing the gold wire in the groove, press down. The pressing force is related to the width of the groove, that is, the pressing force increases with the increase of the groove width. For gold with a purity of 99.99% or higher, when the groove width is 0.1mm~0.7mm, the pressing force is 0.3kg~3.0kg; specifically, the pressing force is 0.3kg when the groove width is 0.1mm, 0.5kg when the groove width is 0.2mm, 0.8kg when the groove width is 0.3mm, 1.5kg when the groove width is 0.4mm, 2.0kg when the groove width is 0.5mm, 2.5kg when the groove width is 0.6mm, and 3.0kg when the groove width is 0.7mm; when the groove width increases by 0.1mm from 0.7mm, the pressing force increases by 1.5kg accordingly. Each downward press should be controlled within 0.3mm to 1mm. Excessive downward press will cause the groove to crack. The pressing force is related to the purity of the gold. 99.99% pure gold is suitable for the parameters listed above. When the purity of the gold decreases by 5% from 99.99%, the pressing force should be increased by 8% accordingly. When the purity of the gold is below 80%, the increased hardness will cause the groove to crack, and the method of embedding gold wire in Helan inkstone cannot be used. In addition, since a trapezoidal groove is opened in step (1), the gold wire can be more firmly embedded in the groove after pressing.

[0038] (4) Hammering and compaction: Hammer the surface of the Helan inkstone on which the gold wire is placed; for cases where the purity of gold is above 99%, the impact pressure of each hammering is 0.2kg~0.4kg and the impact area is less than 2mm. 2 Exceeding the range of impact pressure and impact area will cause the groove to crack. When the gold purity is higher than 80% and lower than 99%, the hammering impact pressure needs to be increased by 20% and the impact area needs to be reduced by 50%. Exceeding the specifications will cause the groove to crack.

[0039] (5) Grouting and stabilization: Apply resin-based adhesives or natural liquid shellac evenly to the working surface of the Helan inkstone with embedded gold wire at room temperature to stabilize the fine crystal structure of the inkstone and enhance its stability. Then place it at room temperature and let it dry naturally for 48 hours.

[0040] (6) Finishing and Polishing: Remove and polish the gold material that is higher than the groove opening. Finishing requires a flat or beveled tool with a cutting edge angle of 5°~10°. If the angle is greater than the specification, the gold will easily pop out of the groove and the groove will collapse and crack. Each time the tool is pushed and scraped, the thickness should not exceed 0.1mm. If it exceeds the specification value, the gold will pop out and the groove will collapse and crack. Polishing should be done with 1000-7000 grit wet sandpaper and water in sequence. That is, first use 1000 grit wet sandpaper on the working surface. If it exceeds the specification value, the groove will collapse and crack and the sand path on the polished surface will be too deep, making it difficult to advance the polishing work in the later stage. After the overall polishing is completed, use 2000 grit, and so on up to 7000 grit to achieve a bright effect and complete the work.

[0041] Example 2

[0042] A manual grooving tool is specifically designed for the fine processing of embedding gold in the Helan inkstone as described in Example 1, namely, step (1) grooving the Helan inkstone; the manual grooving tool, such as Figures 2 to 4 As shown, the device includes a cutting head 3, a handle 4, and a direction indicator plate 5 connected in sequence. The cutting edge plane at the end of the cutting head 3 is trapezoidal, and the direction indicator plate 5 is a trapezoidal plate structure, with its plate plane parallel to the cutting edge plane at the end of the cutting head 3. The trapezoid of the direction indicator plate 5 is a proportionally enlarged version of the trapezoid of the cutting edge (horizontal plane at the end of the cutting head) of the cutting head 3, and its direction is approximately 90° (actually measured as 88.65±0.1°) rotated around the axis of the handle 4. Figure 4 As shown, if the sides of the trapezoidal cutting edge of the blade head 3 are named clockwise as the upper bottom, first side waist, lower bottom, and second side waist, and the sides of the trapezoidal direction indicator plate 5 are named clockwise as the upper bottom, first side waist, lower bottom, and second side waist, then the trapezoidal shape of the direction indicator plate 5 is formed by enlarging it proportionally to the trapezoidal shape of the blade head 3, and then rotating it 90° clockwise or counterclockwise around the axis of the handle 4. In other words, the upper bottom of the direction indicator plate 5, the first side waist, lower bottom, and second side waist of the blade head 3, and the second side waist of the blade head 3 are all named clockwise. The planes on the first side waist of the indicator plate, the lower bottom of the indicator plate, and the second side waist of the indicator plate correspond, respectively, to the planes on the first side waist of the cutting edge, the lower bottom of the cutting edge, the second side waist of the cutting edge, and the upper bottom of the cutting edge, or respectively, to the planes on the second side waist of the cutting edge, the upper bottom of the cutting edge, the first side waist of the cutting edge, and the lower bottom of the cutting edge. This structure allows for the machining of a trapezoidal cutting edge of the tool head, as the grinding surface of the whetstone is the side of the cutting edge, thus enabling the corresponding trapezoidal cutting edge to be machined precisely according to the trapezoidal structure of the direction indicator plate 5. The machining of the tool head 3 is as follows: Figure 5 and Figure 6 As shown.

[0043] The specific process of using this manual grooving tool to groove Helan inkstone is as follows: (1) Grooving begins with the blade edge, which is 0.1mm to 2mm wide and trapezoidal in shape. Manual grooving by eye is very easy to cause the inkstone groove to crack due to the change in the angle of the trapezoidal blade exceeding the standard. The manual grooving tool of this invention is equipped with a direction indicator plate 5 so that the correct cutting angle can be adjusted and determined at any time before cutting. The blade angle is parallel to the direction indicator plate 5 to indicate the blade angle. (2) Cut at a right angle, with a cutting depth not exceeding 0.1mm and a cutting distance not exceeding 3mm each time. This is done sequentially. (3) After reaching the required depth, the blade angle is used to expand the bottom at 120° and 60° along the two bottom edges.

[0044] While the visual effect of this invention is somewhat similar to cloisonné, there are fundamental differences: First, cloisonné is made of copper, while gold and stone inlay involves inkstone and gold; second, cloisonné requires firing after glazing, while gold and stone inlay involves shaping the inkstone and then pressing it onto the brittle Helan inkstone using a specific method. In other words, the gold and stone inlay of this application involves creating grooves on the Helan inkstone before pressing gold, rather than pressing gold onto copper or other metal objects. Based on historical records of inkstone carving art and currently available materials, the creative and technical expression of combining gold and Helan inkstone has not yet appeared in the world of inkstone carving art.
