Ice in a freezer is extremely hard and ice cubes may fuse together. If you use your drinking glass to chip away at a mass of ice, it can wind up chipping pieces of glass from your drinking glass. The chips may wind up in the bottom of your drinking glass, and you would not be able to see them, possibly ingesting the glass, which would cause you to have a bad day. GLASS FRACTURE PATTERNS Name: Jill Parsons Use this site, - analysis/ , to answer the following questions. 1. Examine the diagrams below that show a side view of a window both before and after impact. Determine the point of impact and direction of force. Draw an arrow indicating the direction in which the force was applied to the window. 2. Because glass is made of a variety of compounds, it is possible to distinguish one type of glass from another by examining the different physical and chemical properties. We will examine some of the properties of glass, such as density, refractive index, and fracture patterns that are used in the forensic examination.
