What are your best memories at camp?
One of the best memories for most people is sitting by the campfire and sharing stories. Aside from the warmth from the fire, you can watch the dancing of the flames and see the changes in the color.
But how do the flames change colors? Well, colors change based on the flames’ interaction with chemicals.
If you want a purple flame, all you need is potassium chloride. You can see this chemical in mineral sylvite or a combination of brines and ocean water.
To get a pink flame, you need lithium chloride. It can be found on some igneous rocks. You need strontium chloride or strontium salts to produce a red flame.
For blue and green, you need copper chloride and copper sulfate, respectively. Natural versions of copper chloride are hard to find. It only occurs in very rare anhydrous mineral tolbachite. Meanwhile, copper sulfate can be found in products that control algae in pools.
If you would like to have a white flame, you only need to add magnesium sulfate. Throw in some Epsom salts into your campfire to get the lightest shade of fire.
