==Oil and thermography==

'''Oil''', neutral nonpolar chemical viscous fluid who is liquid at ambient emperature and hydrophobic (not miscible with water) but lipophilic (miscible with other oils or fat).

Substance with high level of hydrogen and carbon, usually flammable and slippery. Origins are animals, vegetable or petrochemical.

They are volatile or no-volatile and their use is very large as food, fuel, lubrication, paints, plastics, religion, ...

The images upper describe the behaviour of a oil's slice who's cooling. Observe that cooling is performed under a cell mode with the size of the cells increasing so as temperature is decreasing.

Regularity is not absolute but seems a good purity test.
