- Today in our scientific procedure, we observed and created a variety of different colored flames, by placing small amounts of metal chlorides over a controlled flame. The colorful fascinating flames that we produced only lasted for a little while, eventually the flames returned to a more solid and more stable condition. Potassium, Sodium, Strontium, and Copper were some of the chlorides used in this experiment. In my opinion the experiment that I was involved in was not an accurate representation of the science behind the color of stars. Colored flames are made from metal Chlorides, whereas the color of stars are made from heat. Cooler stars appears to be the color red, but if it was hotter, it would appear white or blue.
