If you could design a fireworks display what salt would you use and why

Some metals can generate multiple colors, depending on how hot they get. Excluding propellants or special effects, the points of light ejected from fireworks , termed 'stars', generally require an oxygen-producer, fuel, binder to keep everything where it needs to be , and color producer. Incandescence Incandescence is light produced from heat. Even trace amounts of sodium impurities yellow-orange are sufficient to overpower or alter other colors. Rockets are made of cardboard tubes filled with a mixture of fuel and oxidizer in proportions that allow continuous burning rather than explosion. Antimony: Antimony is used to create firework glitter effects. To produce luminescence, energy is absorbed by an electron of an atom or molecule, causing it to become excited, but unstable. Continue Reading. Their colors come from the different temperatures of hot, glowing metals and from the light emitted by burning chemical compounds. It might sound easy, but the science of fireworks is a lot more complicated than it seems. Science news delivered weekly! Burning magnesium, titanium or aluminum can also create silver fireworks, while iron or charcoal burn gold. A simple and safe home experiment can be carried out by squeezing an orange peel near a candle flame. There are two main mechanisms of color production in fireworks, incandescence, and luminescence.

A careful formulation is required so that too much smoke or residue doesn't mask the color. A lifting charge throws the ball skyward, and the explosive charge fires when the embedded fuse burns down after a time period appropriate for the shell to reach the desired altitude.

How do fireworks get their colors

For instance, when sodium nitrate is heated, electrons in the sodium atoms absorb the energy and get excited. The recipe that creates blue includes varying amounts of copper chloride compounds. Burning naphthalene and anthracene produce black smoke that can be used to screen off an Torchlight parade of skiers, Winter Park, Colorado, December 24, Usually, these electrons hang out as close as they can to the nucleus. Titanium: Titanium metal can be burned as powder or flakes to produce silver sparks. The energy of the photon determines its wavelength or color. White smoke produced by vaporizing zinc chloride or oil or burning phosphorus is sometimes used to provide cover during combat; the hydrolysis of silicon chloride SiCl 4 produces a white smoke as well. When the sparkler is ignited, the fuel and oxidizer burn, heating the iron filings so that they sparkle. Image Credit: Intel Strontium carbonate, which burns red Calcium chloride, which burns orange Sodium nitrate, which burns yellow Barium chloride, which burns green Copper chloride, which burns blue Chemists make other colors, like purple, with a mixture of copper and strontium, because — as you may remember your kindergarten art class — red and blue makes purple. Once exposed to fire, the stars' fuel and oxidizing agents generate intense heat very rapidly, activating the metal-containing colorants. Updated July 23, Fireworks are a traditional part of many celebrations, including Independence Day.

Barium: Barium is used to create green colors in fireworks, and it can also help stabilize other volatile elements.

What are metal salts? At the time, people thought these explosions would chase away any evil spirits that were lingering nearby. Here's an element-by-element look at what is involved in your average firework. One of the simplest firework devices is a sparkler.

But how do fireworks work? We see these different light wavelengths as different colors.

Which chemicals generate the following colors in the fireworks?

The amount of heat energy needed to push these electrons away varies for each metal. There are two main mechanisms of color production in fireworks, incandescence, and luminescence. Incandescence Incandescence is light produced from heat. Some metals can generate multiple colors, depending on how hot they get. Several of the metal salts that produce colors contain chlorine. Bananas contain large amounts of potassium; a banana peel in a bonfire shows the characteristic violet color of potassium flames. Antimony: Antimony is used to create firework glitter effects.

Aluminum and magnesium components produce brighter flashes. Expulsion of gases from the tube propels it skyward. Components in Fireworks Aluminum: Aluminum is used to produce silver and white flames and sparks.
