In the present invention, the addition amount of each component is limited for the following reason. If K 2 O is less than 10% by weight, the melting temperature is high and it is difficult to melt, and if it exceeds 30% by weight, the amount of mica deposited is reduced and workability is deteriorated, so the content is limited to 10 to 30% by weight. If the content of BaO is less than 5% by weight, the melting temperature increases, and if it exceeds 25% by weight, the amount of mica deposited decreases, so that the content is limited to 5 to 25% by weight. When the content of MgO is less than 10% by weight, the precipitation amount of mica decreases, and when it exceeds 30% by weight, the melting temperature becomes high, so that the content is limited to 10 to 30% by weight. If the content of Al 2 O 3 is less than 3% by weight, the sintering and crystallization of the glass deteriorates, and if it exceeds 15% by weight, the melting temperature becomes high, so that the content is limited to 3 to 15% by weight. If the content of SiO 2 is less than 20% by weight, the sintering and crystallization of the glass will be poor, and if it exceeds 50% by weight, the melting temperature will be high.
Limited to 50% by weight. If the content of F is less than 5% by weight, the amount of precipitated mica decreases, and if it exceeds 15% by weight, the sintering and crystallization of the glass deteriorates. Therefore, the content of F is limited to 5 to 15% by weight.

In the present invention, when the melting temperature is high, the volatile component F is liable to be scattered, making the production difficult, and the mica is KM
Since g 3 Si 4 O 10 F 2 to KMg 3 (AlSi 3 O 10 ) F 2 are precipitated as a solid solution, the lower limits of all components except for BaO and Al 2 O 3 must be accurately maintained.

Further, if the amount of mica crystals in the crystal is less than 30% by volume, sufficient workability cannot be obtained, so that the amount must be 30% by volume or more.
