[5] The procedure uses different solvents and flames to view the test flame through a cobalt blue glass or didymium glass to filter the interfering light of contaminants such as sodium.

The high temperature of the flame causes the vaporized fuel molecules to decompose, forming various incomplete combustion products and free radicals, and these products then react with each other and with the oxidizer involved in the reaction of the following flame (fire). One may investigate different parts of a candle flame with the aid of a ...

Some flowers will change color at the same rate regardless of pollinator visitation, while others can be induced by pollen deposition on the stigma.
