This week, we received the following questions from our customers:
I observed that when we break the glass with great force, the debris close to the impact point is sometimes large, exceeding the standard of 40 fragments. However, the size of the debris farther from the impact center is small. Is this normal? Or does that mean the glass is not re-igniting correctly? Will the size of the debris vary depending on the impact strength? If this means that our glass does not fire back properly, what can we do to correct it?
The size of the glass fragments depends on where the pieces break. If you break the glass in the center, you can get long pieces, but if you break the glass on the edge, the fragments are usually smaller. That's because you have different boundary conditions, depending on whether you break the glass at the center or at the edge.
If fragments are broken even if the glass is broken in the center, stress levels can be increased by refracting the glass at higher temperatures and with higher cooling capacity. The size of the fragment then becomes smaller.
