METHOD FOR SEPARATING COMPONENT IN AJI STONE, METHOD FOR PRODUCING STAIN USING AJI STONE AS RAW MATERIAL, AND BLUE LIGHT CUT GLASS INCLUDING AJI STONE IN RAW MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a method for separating the components in an Aji stone capable of separating the effective components from the stone dust of an Aji stone, a method for producing a stain using an Aji stone as raw material capable of performing dying to a unique color tone, a method for separating the components in an Aji stone, and a blue light cut glass including an Aji stone in the raw material.SOLUTION: A tannin liquid including tannin is mixed with the stone dust of an Aji stone, and this state is held. When the tannin liquid is mixed with the stone dust of the Aji stone, and the mixture is made left, it is separated into the layer of a supernatant, the layer of a liquid including a mineral, the layer of silicon (silica) and the layer of the other substance. Thus, the substances of the respective layers can be effectively utilized.SELECTED DRAWING: Figure 1
