Low melting point
Long melting interval
High melting viscosity
At high temperature, it can dissolve quartz, clay and mullite quickly and has high solubility
Low melting temperature, good transparency
The melting temperature range is narrower than K-feldspar. The viscosity of the melt is small at high temperature and changes rapidly with temperature
