Glass Analysis

any characteristic that can be observed without changing the substance (weight, color, density)

a property of matter that describes a substance's ability to participate in chemical reactions

formula for density

the bending of light as it passes from one medium to another

speed of light in a vacuum/ speed of light in a medium

a line perpendicular to the surface where two mediums meet

a hard brittle, amorphous substance composed of silicon dioxide

is added to sand to lower it's boiling point and make it easier to work with (soda)

added to prevent "soda lime" to prevent it from dissolving into water (lime)

solid whose atoms are arranged in a random fashion

boron oxide added to glass to increase resistance to heat

substitutes lead oxide for calcium oxide

glass heated and cooled repeatedly to add strength (doesn't shattered when it breaks)

two sheets of ordinary glass bonded with plastic

a halo observed around the edges of a particle during a refractive index

straight cracks that radiate outward from the center like the spokes of a wheel

cracks that form a rough circle around the center

gunshot residue, a crater shaped symmetrical hole, wider on one side than the other ( all evidence of...)

combination of 2 or more hard and soft glasses

a small amount of glass fragments projected backwards
