Answer #1

When I was a kid we used to make colourful fires by inserting garden hose into a copper pipe that had holes drilled through it.

Now that I realize how bad it was for the environment I really don’t recommend you do that.

There are all these chemicals that change the colour of fire: Copper Chloride : blue Borax : light green Copper Sulfate: green Lithium Chloride: pink or red Potassium Nitrate: purple Epsom Salt: White Strontium Chloride: makes red flame in campfire. Potassium Chloride: makes a deep purple flame in campfire. Alum (thallium): a nice bright green flame in campfire. Used for pickling but can also buy cheap at drugstore Calcium Chloride : nice blue flame - is sold commercially as the product ” Damp-Rid” to get rid of moisture. Table Salt (sodium chloride)- make an orange flame. Boric Acid - deep red flame. Buy at any pharmacy.

Answer #2

A lot of those chemicals are VERY dangerous. If you can attain them, it would be smarter to NOT throw them in a fire since some are can be explosive when mixed with certain chemicals. If you want to see, go to http://hazard.com/msds/ to check on how dangerous some of these are. The potassium nitrate is a severe irritant that can cause pain if you touch it with your fingers just for one example…
