What is the Chemical Basis of Colour in Fireworks? Abstract: The purpose of the first experiment was to see the light spectra of different elements‚ and confirm that each element shows unique emission spectra‚ in terms of being able to identify an unknown substance. The analysis is expected to show that elements do indeed have unique emission spectra‚ allowing elements to be identified by their emission spectra. After burning different chemicals under a Bunsen burner‚ the colourful light was

1. Colour Fastness to Light This method is intended for accessing the resistance of the colour of textiles to the action of daylight. Principle: A specimen of the textile is exposed to the light from a Xenon arc lamp under prescribed conditions‚ along with eight dyed wool standards. The fastness is assessed by compared the fading of the textile with that of the standards. Apparatus and Materials: - Blue standards - Humidity Test Control Fabric - Light fastness test apparatus containing

Color stratification has been a part of American History since the days of slavery. During slavery light skinned Blacks were freed earlier than dark skinned Blacks.
