The composition of the raw materials (components) of the refractory 1 chamotte 1 is shown on the N side. No. 2 is a stone with a particle size of 0.3 + m or more, and No. 3 is a clay particle. Generally, the clay 3 is sufficiently finely divided, so it does not turn into gravel and the above-mentioned problem does not occur.Of course, if the diameter of the 5 stones 2 is 0.31 nm or less, it will not cause foot discomfort. , Other than that, it doesn't matter how small it is. When making crucibles using chamotte or waxite as the main raw materials, the strength characteristics of the crucible and the [spalling properties] need to be increased. Therefore, it is required to blend chamotte and dolomite with appropriate particle sizes, and it is also required to contain a considerable amount of coarse particles with a particle size of 0.3 mm or more.

1. Along with r4 masaru, it is possible to make a homogeneous one-piece shimosoto. Therefore, if a crucible for glass hydrolysis is made using such chamotte as one of the main raw materials, it is possible to make a crucible with sufficiently high strength and spalling resistance.
In addition, the particle size of clay, which is the main raw material, and 5-chiroite, which is contained in Tsukitsu Chamotte refractories, is set to 0.3 mm or less at the largest, and the particle size of 5-chiroite, which is included in the Tsukitsu Chamotte refractory, is also as described above. Since the thickness was set to 0.3 mm or less, it is inevitable that the glass products would have defects as described above.
