Glass crushing test

**Summary**
The particle size distribution was measured when glass fragments were crushed using an automatic mortar AGB. After crushing standard microscope slide glass to about 3.5mm, it was further pulverized using the automatic mortar AGB. The crushing time was 5 hours, and the particle size measurement was conducted using a laser diffraction device.
**Conclusion**
Glass fragments of standard microscope slide glass crushed to about 3.5mm were pulverized using the automatic mortar (Ishikawa-type stirring grinder) AGB. The particle size reached saturation in about 3 hours, achieving a size of approximately 1.7μm.
**Testing Equipment**
- Testing Equipment
- Automatic mortar (Ishikawa-type stirring grinder): AGB
- Laser diffraction/scattering particle size distribution measurement device: LA-950V2 (Horiba, Ltd.)
*Note: The measurement of particle size distribution was outsourced to an external organization.*
**Test Results**
When glass fragments of standard microscope slide glass crushed to about 3.5mm were pulverized using the automatic mortar (Ishikawa-type stirring grinder) AGB, the particle size saturated in about 3 hours. The particle size was approximately 1.7μm. Therefore, it is possible to crush glass to a particle size of about 1.7μm using the AGB type.
