Can date sites with clay quite accurately, or when something is out of context. Date pottery and rocks that have been heated at about 500ºC or higher.2. HOWEVER: Very poor precision.-Electron traps set to zero when heated. Date minerals which have been exposed to light by several minutes' exposure to sunlight.

Drawback: some minerals don't capture sufficient amounts of sunlight, therefore are dated as older... Based on principle that when volcanic obsidian is fractured, it starts absorbing water from its surroundings, forming a hydration layer that can be measured.
