る。In such conventional colored sand, coloring obtained from dyes such as red, blue and yellow is possible, but coloring such as metallic gold or silver is difficult or impossible. there were. The cause is not always clear, but because silica gel is porous and lacks luster, when metal powder is used instead of a dye to obtain a metal color, the metal powder enters the silica gel and silica gel It is presumed to be due to cracking. An object of the present invention is to provide a colored sand having an unusual high-grade feel for an hourglass by succeeding in coloring a metal color that has not been obtained conventionally by repeating a trial production in consideration of the above conventional circumstances. is there.

An alloy powder of copper, aluminum, tin, zinc, or the like, the amount of which is set according to the desired metal color. For example, when gold metal powder is used, the amount of copper is increased, and when silver metal powder is used, the amount of aluminum or tin is increased. Further, since the metal powder is coated on the outer periphery of the silica gel, the metal powder is considerably smaller than the silica gel, and about 1000 mesh is used. The mixing ratio between the silica gel and the metal powder is such that the higher the ratio of the metal powder, the deeper the metal color. Preferably, the ratio is such that the silica gel is not exposed. Generally, silica gel 2 to metal powder 1
The blending ratio is 2.5.

（CC）とする。[0006] The solvent has a function as a binder for adhering the metal powder to the silica gel, and it is preferable to use the same type, specifically, a metal alkoxide as a main component in correspondence with the metal powder. Specifically, it is a solution composed of alkoxysilane (tetraethoxysilane), ethanol, water, and acid (adjusted to 1.8 PH with hydrochloric acid or sulfuric acid), and their mixing ratio (molar ratio) is 1: 6.8: 11. : 1 is used as a solvent. The amount of the solvent is set based on the amounts of the metal powder and the silica gel, and the amount (CC) is substantially equal to the amount (g).

て使用に供される。The silica gel, the metal powder and the solvent are first sufficiently mixed with the silica gel and the metal powder, then the solvent is added thereto, and the mixture is stirred and then heated and dried. The heat treatment removes the alcohol in the solvent and gels the silica gel to coat the outer periphery of the silica gel with the metal powder. In order to prevent the coating film from peeling, it is preferable to gradually heat the coating. The drying process is
This is a step of removing water at a heating temperature or a high temperature state higher than the heating temperature. The process is performed following the heating process or simultaneously during the heating process. If the drying process is performed in a vacuum, the processing time is shortened, but it may be performed in the air. After the drying treatment, heat is radiated at room temperature to complete colored sand, and the sand has a form in which the color of the coated metal powder is directly colored. The above colored sand is thereafter subjected to a sieve to equalize the particles, and is used as sand for an hourglass.
