You can use <u>conchoidal </u>fractures to tell the direction from which a projectile struck glass.
Conchoidal fracture, frequently seen in quartz and glass, is referred to as a fracture with smooth, curving surfaces that resemble the interior of a seashell. Rapidly applying stress to fragile things causes the fracture surface to grow with a smooth curved surface. Such materials frequently exhibit conchoidal fracture because they lack a crystalline structure or cleavage. Glass develops ridges along the edge when a bullet strikes it; these fractures are apparent in profile. These fractures are almost parallel to the direction of applied force (the direction which the projectile came from).
