Manufacturing method of chemically strengthened glass plate and glass plate accommodating body for chemical tempering

摘要

In the present invention, a glass plate (G) is chemically strengthened by holding a first side edge (G1) of the glass plate (G), suspending the glass plate (G) with the held first side edge (G1) placed upward, and dipping the glass plate (G) into molten salt while suspending the glass plate (G) for a salt bath treatment. This allows glass plates to be chemically strengthened at high yield and with high quality, and significantly improves the productivity of chemically strengthened glass plates.
