Preliminary Practice

Lipstick analysis

A lip-print, perhaps left on the body of a victim or maybe a letter or note, is as distinctive as a fingerprint, and though they are often unrecognized for their significance, can offer very crucial evidence in a case. We analyzed our lip-prints in this activity, then tried to match the prints of another group with the original prints based on parallels in the prints. Our group achieved 100% accuracy in the matching of prints.

In this activity we also attempted chromatography on the various lipsticks in the lab since the type of lipstick is also very useful when attempting to determine who left a lip-print. However, none were soluble in the solution and we were unable to properly analyze the lipstick itself.
