Abstract
Description
この発明は、表面に彫刻を施した銀粘土焼結体の製造方法に関するものであり、さらにこの発明は表面に彫刻を施した銀粘土焼結体を製造するために使用する表面に黒または薄黒い色調の硫化銀膜を形成した彫刻を施し易い銀粘土造形体に関するものである。 The present invention relates to a method for producing a silver clay sintered body having a surface engraved, and the present invention further relates to a method for producing a silver clay sintered body having a surface engraved. The present invention relates to a silver clay shaped body that can be easily engraved with a black color silver sulfide film.
近年、通常の粘土細工と同じように自由に造形を行うことができる銀粉末を含んだ銀粘土が市販されており、この銀粘土を用いて表面に彫刻を施した指輪、腕輪、ペンダント、置物などの銀粘土焼結体からなる宝飾品や美術工芸品を個人的に製造している。銀粘土焼結体からなる宝飾品や美術工芸品を製造するには、銀粘土を所定の形状に成形して銀粘土造形体を作製し、この銀粘土造形体を乾燥して固化したのち銀粘土造形体の表面に彫刻を施し、この表面に彫刻を施した銀粘土造形体を焼結して所定の形状を有し彫刻が施された銀粘土焼結体からなる宝飾品または美術工芸品を製造している。 In recent years, silver clay containing silver powder that can be shaped freely like ordinary clay work has been marketed, and rings, bracelets, pendants, figurines that have been engraved on the surface using this silver clay Jewelery and arts and crafts made of silver clay sintered bodies are manufactured personally. To produce jewelry and arts and crafts made of sintered silver clay, silver clay is molded into a predetermined shape to produce a silver clay model, and this silver clay model is dried and solidified. Jewelery or arts and crafts made of a silver clay sintered body that has a predetermined shape by engraving the surface of the clay model and sintering the silver clay model that has been engraved on this surface Is manufacturing.
例えば、図5の側面図に示されるように、腕輪の側面に誕生日または作製年月日を彫刻した銀粘土焼結体からなる腕輪1を作製するには、銀粘土を造形して得られた図3の側面図に示されるようなリング状の銀粘土造形体2を作製し、この銀粘土造形体2を乾燥したのち図4に示されるように銀粘土造形体2の側面に誕生日または作製年月日を彫刻し、この彫刻した銀粘土造形体2を焼結炉で焼結することにより誕生日または作製年月日を彫刻した銀粘土焼結体からなる図5の側面図に示される腕輪1を作製していた。
For example, as shown in the side view of FIG. 5, in order to produce the

Silver powder: 50 to 95% by mass, organic binder: 0.8 to 8% by mass, fat / oil: 0.1 to 3% by mass, surfactant: 0.03 to 3% by mass, the rest being water, Silver clay blended so as to have a composition consisting of the above is provided, and these silver clays are all excellent in low-temperature sinterability and can be sintered with solid fuel (see Patent Document 2).
しかし、従来の方法で銀粘土造形体2の表面に彫刻を施すと、彫刻を施した部分と銀粘土造形体2とが同じ色彩を呈しているので、図4に示されるように、彫刻を施した部分3と施さない部分との色調の相違が見られないところから、どのような彫刻を施したのか明確に認識することが難しく、特に細い線の彫刻を銀粘土造形体に施しても彫刻した部分と彫刻しない部分との判別をすることは容易ではない。
However, when the surface of the
また、彫刻した部分と彫刻しない部分との識別が認識できないと正確な模様または文字が彫刻された銀粘土焼結体からなる宝飾品または美術工芸品を得ることができない。 Further, if the distinction between the engraved part and the non-engraved part cannot be recognized, it is not possible to obtain jewelry or arts and crafts made of a silver clay sintered body engraved with an accurate pattern or character.
そこで、本発明者らは、銀粘土造形体の表面にいかなる模様または文字を彫刻したかがはっきりと分かるようにすべく研究を行った結果、市販の銀粘土を造形して得られた図3に示される銀粘土造形体2を硫化処理することにより表面に黒または薄黒い色調の硫化銀膜を形成した図1の側面図に示される銀粘土造形体4を作製し、この表面に黒または薄黒い色調の硫化銀膜を形成した銀粘土造形体4に彫刻を施すと、図2に示されるように、彫刻を施した部分3は銀粘土造形体自体の白色が現れ、彫刻を施さない部分は硫化銀膜は黒または薄黒い色調を呈しているところから、彫刻を施した部分3と施さない部分との色調のコントラストが明確となり、彫刻を施し易くなると共に一層正確な彫刻を施すことが容易になる、という知見を得たのである。
Therefore, the present inventors conducted research to clearly understand what pattern or character was engraved on the surface of the silver clay modeled body, and as a result, FIG. 3 was obtained by modeling a commercially available silver clay. The
この発明は、かかる知見にもとづいてなされたものであって、

(2)表面に硫化銀膜が形成されている銀粘土造形体、に特徴を有するものである。
This invention was made based on such knowledge,
(1) Silver clay is modeled to produce a silver clay model, and the resulting silver clay model is sulfidized to produce a silver clay model having a silver sulfide film on the surface. A method for producing a silver sintered body having a sculpture on the surface to be sintered after engraving the silver clay model having
(2) It is characterized by a silver clay shaped body having a silver sulfide film formed on the surface.
この発明の表面に硫化銀膜が形成されている銀粘土造形体4は、図3に示される通常の銀粘土造形体2を硫酸ナトリウム水溶液に浸漬することにより形成することができるが、その他の方法で硫化処理することにより成形することもできる。この硫化銀膜が形成されている銀粘土造形体に彫刻を施したのち、焼結すると、銀粘土造形体表面に形成されている硫化銀膜は還元されて銀となり、表面が銀色の銀粘土焼結体を作製することができる。
The silver clay shaped body 4 having a silver sulfide film formed on the surface of the present invention can be formed by immersing the ordinary silver clay shaped
上述のように、この発明の銀粘土焼結体の製造方法によると、一層繊細な模様または文字を正確に彫刻した銀粘土焼結体からなる宝飾品または美術工芸品を簡単に作ることができるなど優れた効果を奏するものである。 As described above, according to the method for producing a silver clay sintered body of the present invention, jewelry or art crafts made of a silver clay sintered body accurately engraved with a more delicate pattern or character can be easily produced. And so on.
実施例1
市販の銀粘土を造形して図3に示される銀粘土造形体からなるリングを作製し、このリングを乾燥し固化させたのち、この固化した銀粘土造形体を1.0%Na2SO4水溶液中に浸漬することにより、図1に示されるように固化した銀粘土造形体の表面に硫化銀膜を形成した硫化銀膜被覆銀粘土造形体を作製した。この硫化銀膜被覆銀粘土造形体に図2に示されるように彫刻を施したところ、彫刻を施した部分が銀粘土造形体の銀色を呈し、一方、彫刻を施さない部分は黒色を呈しており、彫刻を施した部分が鮮明になった。
Example 1
A commercially available silver clay is modeled to produce a ring made of a silver clay modeled body shown in FIG. 3, this ring is dried and solidified, and then this solidified silver clay modeled body is treated with 1.0% Na 2 SO 4. By immersing in an aqueous solution, a silver sulfide film-covered silver clay shaped body in which a silver sulfide film was formed on the surface of the solidified silver clay shaped body as shown in FIG. 1 was produced. When this silver sulfide film-coated silver clay shaped body is engraved as shown in FIG. 2, the engraved portion exhibits the silver color of the silver clay shaped body, while the unengraved portion exhibits black color. The engraved part became clear.
従来例1
実施例1で用意した市販の銀粘土を造形して図3に示される銀粘土造形体からなるリングを作製し、このリングを乾燥し固化させたのち、この固化した銀粘土造形体の表面に図4に示されるように彫刻を施したところ、彫刻を施した部分および施さない部分が共に銀粘土造形体固有の白色を呈しているのでコントラストが鮮明でなく、彫刻を施した部分と施さない部分との区別が不鮮明にであった。
Conventional Example 1
The commercially available silver clay prepared in Example 1 is shaped to produce a ring made of the silver clay shaped body shown in FIG. 3, and after the ring is dried and solidified, the surface of the solidified silver clay shaped body is formed. When engraved as shown in FIG. 4, both the engraved part and the non-engraved part exhibit a white color unique to the silver clay model, so the contrast is not clear and the engraved part is not applied. The distinction from the part was unclear.
