Abstract: Determining a temperature experienced by a region of a component comprising the steps of: providing a component with a temperature sensitive detection material in a first state and exhibiting a first chemical characteristic prior to its exposure to a thermal environment; exposing the component to a thermal environment such that the detection material is converted to a different state in which at least one region of the detection material exhibits at least one chemical characteristic different to the first chemical characteristic; identifying at least one region of the component in which the detection material exhibits the at least one chemical characteristic which is different to the first chemical characteristic; and determining the temperature experienced by the component in the or each region by relating the detection material chemical characteristic in the or each region to a temperature value by reference to a correlation of detection material chemical characteristic and temperature.
