The metal salts are packed into small pea- to plum-sized pellets called вЂњstarsвЂќ or вЂњ pyrotechnic stars.вЂќДЄfter a firework is ignited, a lift charge propels it into the sky. Purple fireworks are typically produced by use of a mixture of strontium (red) and copper (blue) compounds. Metal salts commonly used in firework displays include: strontium carbonate (red fireworks), calcium chloride (orange fireworks), sodium nitrate (yellow fireworks), barium chloride (green fireworks) and copper chloride (blue fireworks).

Some of these compounds produce intense colors when they are burned, which makes them ideal for fireworks. These salts are different from table salt, andВ in chemistry вЂsaltвЂ™ refers to any compound that contains metal and non-metal atoms. TheyвЂ™re created by the use of metal salts. The colors in fireworks come from a simple source: pure chemistry.

Still, itвЂ™s fun to recall the reds, oranges, yellows, greens, blues and purples exploding in the skies, creating вЂњohhhhsвЂќ and вЂњahhhhs.вЂќДЄnd itвЂ™s interesting to know what creates those brilliant colors. So you might or might not see fireworks (a type of pyrotechnics) this year.
