Document Summary
Taking a sample, adding elements (e. g. electricity) that excites it, and it emits light. As each element relaxes back to its normal state, it emits an amount of energy that is specific to its own element. The energy that the atoms absorbs does not equal to the amount of energy that it will emit. Passing our sample through a hot plasma (charged ions) that can heat it up and give energy to the sample. As it relaxes, it emits energy at specific wavelengths. Clearcoat: either the colour is imbedded into the clear coat, or a separate colour is painted and the clearcoat is painted over to protect it. Binder: liquid at first, hardens after contact with surface: holds onto the pigment and protects it. Pigment: powders that give paint its colour: suspended and does not dissolve, are inorganic substances containing transition metal ions (middle of periodic table)
