FIREWORKS ELIZABETH WILSON More than 1,000 years ago, most likely in China, someone made the serendipitous discovery that a mixture of sulfur, charcoal, and saltpeter (potassium nitrate) burned with startling speed and flash. The mixture, which eventually came to be known as gunpowder, was a Chinese mainstay for centuries, used in ceremonies to scare off evil spirits and even in military rockets. Gunpowder made its way to Europe, probably during the early 1200s. During the Middle Ages, gunpowder-based creationsthe precursor to modern fireworkswere limited to booms and a few sparkles, aided by a few iron filings or some copper or zinc. The repertoire of colors was that found in most campfires: oranges, yellows, and the occasional white-hot. It wasn't until the 1800s that chemists began to use then-recently synthesized compounds that, in the right mixtures, burned in reds, greens, even blues and purples, and that the colors we traditionally ascribe to fireworks began to show up in night skies.
