When you excite an element with enough energy, it prompts one of its electrons to jump into a “higher” energy state. Toxic Chemicals in Fireworks: Might Want to Hold Your Breath. For white, silver, and shimmering fireworks, makers rely on magnesium, titanium, and aluminum salts.Building upon the previous work of Dr. David Alter in the 1850’s, German philosophers Gustav Kirchhoff and Robert Bunsen (and yes, that is the same scientist after which the Bunsen Burner is named! In red fireworks, strontium salts are typically used. Then, the electron will lose some of its energy and “fall” back down into its lower energy state. Moreover, in order to characterize the chemical properties of firework aerosols, three kinds of firework powders obtained from the same manufacturing factory producing Kaohsiung Lantern Festival fireworks were burned in a combustion chamber.

This chemical must not come in contact with the skin as severe burns can result. The color of this light is directly related to the energy difference between an electron’s “higher” energy state and its “lower” energy state.

Creating firework colors is a complex endeavor, requiring considerable art and application of physical science. Fireworks utilize a precise chemical mixture. x�\˒ܶ��+���E5�w�r�8Qy�&�x��f�i[RsL�m�_f��O�K� ѶS�RU7E��q���N�M}�����+uR�_|���'u�}��;�L����;dm�u�j�"�����ݕ��x�u�Q=�2�*WW���*}u�3dT���~�O|�v��G���t��;�Ou�'���q�Yʛ*+;�:����d�%M�R�SW����sj�b�v��o��*kt�o�+�7(�2j��O;�l�\�)��ߎ�HR��BG����>�9D�W����P���r��W�L7M�I���~U0�(jQ�(�Ҷ+�>~ Ԡ�����(�ƹ=�����cg:�^�O��@�I���]Hc�֣C�u�y�8ݩ��_�o!l� �'�FҕJ����C���T�������\m��Z��.�,ʬm�C�j�2���i�I!-�� �2��I�G���d�b

They discovered that fireworks required four basic elements to burn at the right time and at the right temperature: an oxidizer (a chemical compound that provides oxygen to burn), a fuel (a chemical compound that is flammable), a binder (a chemical that acts like a glue to combine all of the necessary chemicals), and a colorant (the chemical that provides the color, shine, and shape of the firework). The Chemistry of Fireworks How the ancient Chinese discovery of gunpowder and a scientist burning different metals led to the fireworks we know and love today.
