Best wishes for a fun filled summer day on this 4th of July to all! Many of you will be enjoying a fireworks display this evening but have you ever wondered what makes all those brilliant colors? Well, according to the USGS it comes from the minerals that are used… here’s some details:
Red Fireworks and Strontium—Strontium gives a brilliant red hue to fireworks and to the flares you might be toting in your car in case of roadside emergencies. Strontium is produced most notably in the mineral celestite. Strontium is used in drilling fluids to produce oil and gas; it also strengthens metal castings in airplanes and cars, and makes paints that resist corrosion.
