る。First, each of the above-mentioned materials and their manufacturing method will be explained. (a) Precious Metal Powder The particle size of the gold powder has a large effect on the moldability of the alloyed gold clay, its crackability during drying, and the like. Therefore, gold powder is produced by an in-liquid reduction method that has less variation in particle size and has good controllability. For more details, see 46
5 l of AuCl3 aqueous solution with a concentration of g/l and 70 g/l
5 liters of K2SO3 aqueous solution having a concentration of 100 ml is quickly mixed in a temperature range of -10°C to +5°C, preferably at a temperature of +2°C. As a result, the reaction shown in the following formula occurs, and gold precipitates after 5 to 10 seconds. 2AuCl3+3K2SO3+3H2O→2Au+3K
2SO4+6HCl The precipitate thus formed is filtered and dried to obtain gold powder. The temperature range for mixing was determined as above because mixing at a temperature lower than -10°C slows down the reaction rate significantly, and mixing at a temperature higher than +5°C results in the size of the gold particles forming the precipitate. This is because the particles become too small and aggregate. By the in-liquid reduction method under the above conditions, gold powder having a particle size of about 10 μm and having bumps can be obtained. Furthermore, in order to obtain a gold alloy clay having desired properties, the following noble metal powders to be included in the gold alloy clay are manufactured by a gas atomization method. [Alloy powder containing Ag or Cu] By changing the content of these precious metals, the hardness, strength, color tone, etc. of the alloy gold clay can be adjusted. Regarding color tone adjustment, Ag is effective in emphasizing white;
Cu is effective in emphasizing red color. [Alloy powder containing Ni or Pd] These noble metals are particularly effective in emphasizing white color. [Powder containing an alloy of Zn, Co, Be, Sn or In] Zn is effective for adjusting color tone. Also, Co, B
E, Sn, In, etc. are effective in improving the strength of alloyed gold clay. In addition to manufacturing the above materials in the form of an alloy, powders of each noble metal may be manufactured independently and mixed after manufacturing. The gold powder and other alloy powder obtained as described above are mixed at a ratio of 75%:25% to obtain a noble metal powder to be included in the clay. The content of noble metal powder in the alloy gold clay was 50 to 90% by weight. Precious metal powder is an important element that affects the color tone, hardness, and other properties of alloyed gold clay, but if the content of precious metal powder is less than 50% by weight, it has no effect; on the other hand, if the content exceeds 90% by weight, This is not preferable because the elongation and strength of the obtained alloyed gold clay will decrease. Therefore, the content was set as above. Further, the average particle size of the noble metal powder is preferably 200 μm or less, since if it exceeds 200 μm, the elongation and strength of the noble metal alloy gold clay will decrease. In particular, as for the gold powder, since it greatly influences the properties of the alloyed gold clay as described above, a knobbed powder with an average particle diameter of about 10 μm obtained by an in-liquid reduction method is used.

However, if the amount added is less than 0.8% by weight, the effect cannot be obtained, while if it is added more than 8% by weight, the viscosity becomes too high, making it impossible to shape. Therefore, as described above, the content of the cellulose water-soluble binder was set to 0.8 to 8% by weight. As the cellulose-based water-soluble binder, methylcellulose, ethylcellulose, etc. are preferable. (c) Surfactant Adding and mixing a surfactant has the effect of pulverizing the solid matter produced by the reaction between the binder and water, and improving the miscibility of the noble metal powder and the binder. It will be done. However, if the amount of surfactant added is less than 0.03% by weight, the effect is not sufficient. On the other hand, if the amount of surfactant added is more than 3% by weight, the viscosity of the alloyed gold clay decreases and the fluidity increases. This is not preferable because it increases the elasticity and makes it impossible to model. Therefore, as mentioned above, the amount of surfactant added was 0.03 to 3% by weight. (d) Fats By adding a small amount of fats and oils, it is possible to prevent precious metal alloy gold clay from adhering to hands during modeling. However, if the amount added is less than 0.1% by weight, the effect cannot be obtained, while if it is added more than 3% by weight, the alloy gold clay becomes oily and slippery, reducing workability during modeling. I don't like it because it makes it worse. Therefore, as mentioned above, the content of oil and fat was set to 0.1 to 3% by weight. The fats and oils include higher organic acids such as phthalic acid and higher organic acid esters such as n-dioctyl phthalate and phthalate.
n-dibutyl, n-octyl phthalate, isooctyl phthalate, higher alcohols, higher polyhydric alcohols, such as polyvinyl alcohol, polyethylene glycol,

Next, a surfactant is added to this agar-like material and mixed, and the above-mentioned noble metal powder is further added and mixed. By adding oil and fat to this precious metal powder mixture and mixing it, as shown in FIG. is obtained.
