So maybe one day we could see an American-flag firework for the Fourth of July.ĮDITOR'S NOTE: This video was originally published in July 2019. Narrator: And even if we never find that brilliant blue, there's still plenty to get excited about on the horizon, like fireworks that burst into different shapes and patterns, even letters. There could be a breakthrough one of these days. Narrator: But there's still hope for bright blue.Ĭonkling: Certainly it's possible. But it's been a long search, and we're not there yet. Narrator: To be fair, we've gotten close-ish.Ĭonkling: There are some respectable pale blues that are used in special effects, where the audience is closer to the action, where the color is more visible. And even if we do, we'd better hope that it's cheap and non-toxic.Ĭonkling: Arsenic, for example, has been used in some old fireworks formulations, but obviously an arsenic compound is not something you'd want to put up in the smoke where people are watching the fireworks. We have relished fireworks for millennia, and it goes without saying that they are. The instability of compounds that impart that blue color in fireworks is the culprit. And even after centuries of searching, we still haven't discovered the right one, nor have we found a more stable replacement for copper chloride. Table of Contents (click to expand) Blue firework are more difficult to create compared to other colors due to the weird chemistry that comes into play at higher temperatures. But to make a blue firework, you need copper chloride, which is much more fragile.Īs soon as it gets hot enough to blaze blue, at least 1,000 degrees Fahrenheit, it starts to break down. Strontium chloride, the compound used to make red fireworks, can withstand at least 1,500 degrees Fahrenheit. Because temperatures that are too hot will break down those molecules and wash out the color.īut some molecules are hardier than others. That explosion heats up those color-producing compounds, causing them to glow.Ĭonkling: The hotter you can get the molecules in your flame the more ignition you're going to get, so the brighter and more intense the flame color is going to be. When the fuse burns up it sets off the gunpowder, which explodes. You mix this stuff up into what's called a pellet and then shoot it into the air. You see, to make fireworks, you need four basic components: Fuel, usually gunpowder, a compound that produces color, a fuse, and glue to hold it all together. He's one of the world's leading experts in pyrotechnics, and he says the problem comes down to chemistry. John Conkling: The blue has been very, very difficult to achieve at a level comparable to the greens and reds and whites, just because it's a stability issue at high temperatures. Pyrotechnicians have tried to produce blue fireworks for centuries, and they have yet to succeed. They flood the sky with brilliant bursts of scarlet, emerald, and ivory. Narrator: Fireworks have been around for millennia. IPad 3, iPad 4, iPad Air, iPad iPad, iPad Mini 2, iPad Mini 3, iPad Mini 4, 9.Account icon An icon in the shape of a person's head and shoulders.
