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

The chemistry of fireworks The composition of fireworks The main part of fireworks is concerned with pyrotechnics – it is a mixture of substances designed to produce an effect by heat, light, sound, gas, smoke or a combination of these through self-sustaining exothermic reactions that do not rely on oxygen from external sources. When fireworks explode, numerous chemical reactions take place. Copper compounds yield a blue color when burned.

In fireworks, five basic ingredients are usually combined. I hope that the next time you look up into the colorful night sky on the fourth, you can come to see the wonder and the science behind the local firework display. Posted on July 16, 2020 July 16, 2020 by Justin Dingman.
The combustion chamber, with dimensions of 1 m (L) × 1 m (W) × 2 m (H) was self-designed for this particular study. Interestingly, purple fireworks use a combination of copper and strontium salts. �)�yQa�-b���-@1����5L&ҫ������-��W��D0��ew1=t(�#�D��7=m�El���H��m)[��d�~Q�^L��SשA��]�i]VY^0}�a/ ]�ӛk��ܿ'�I���Kl��;'EO?�hj�.o�����\U�FZ�{F2�ދ��
However, during this past fourth, while watching the fireworks with my nieces and nephews, they all gathered around to ask me one simple question: “Uncle Justin, how do fireworks work?”It didn’t take long for chemists and firework artisans alike to figure out the perfect recipe for fireworks. << /Length 5 0 R /Filter /FlateDecode >> This month brings many reasons to celebrate, from America’s fourth of July to France’s Bastille day. 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.
Happy July everyone! Chemicals react to form colored light and sound as energy is released.

Scientists took interest in this phenomena as they began to synthesize and burn chemicals in order to see their spectra, or their visible energy.that began to make up fireworks were dependent on the different types of chemicals used in the firework making process, and this still rings true today. ^�1�� Amber This is a fossil resin of vegetable origin and is yellowish-brown in color.
