The term "coating mold" refers to a coating liquid in which a powder or paste refractory material is dissolved in alcohol or water and preliminarily kneaded, and a so-called coating material is further added with water to maintain an appropriate concentration. When controlling the concentration of the coating liquid, conventionally, the concentration of the liquid has been manually measured using a so-called Baume meter (see FIG. 6) that measures the specific weight of the liquid based on the principle of the float. That is, in FIG. 6, a Baume meter (specific gravity meter) R having a glass rod g is provided with a specific gravity scale S on the surface of the glass rod g. The Baume meter R is placed in a floating state in the liquid W on the liquid surface L. In the figure, p indicates the place where the liquid surface is rising due to the surface tension.
