A chemical property describes the behavior in relation to another substance.
It can be lodged in a suspects shoes or clothes.
Headlight glass can help identify a suspect’s vehicle.
Glass is made of silicon oxide and metal oxides.
Sand and metal oxides are melted and then cooled.
Window and bottle glass are made of soda-lime, sand and metal oxides.
Auto headlights and heat-resistant glass also have boron oxide.
Tempered glass is stressed glass that is rapidly heated and cooled.
Laminated glass is used as windshields and is made by sandwiching a piece of plastic between two pieces of window glass.
Pieces are put together like a puzzle. Refractive index: velocity of light in a
vacuum divided by the velocity of light in the medium.
Density: the mass divided by the volume.
