Easy Purple Fire Project
Loading...
Uploaded by futsang on Dec 3, 2011
Make purple fire using common chemicals. You can vary how pink or blue the shade of purple is by changing the ratio of the chemicals. The blue-violet color is supplied by a potassium salt in salt substitute, which is edible. The red-violet color comes from strontium nitrate, which is found in red emergency flares. While a flare is not edible, the strontium compound generally is considered to be non-toxic.
The background music is "Sodium" by Azareal (Anne Helmenstine).

Does this look any different under a blacklight?

Hi futsang, I want to have purple oil lamps at my upcoming wedding, but I realized I cannot dissolve potassium chloride in methyl alcohol. How can I dissolve it so I can use the potassium chloride in an oil lamp?

I didn't actually see you create any magenta colored flame like the one shown in the preview image of the video. I seen very little color changes at all during your demonstration. Wonder why that is

So without the red flare it would just be blueish

GREEN FIRE! Barium Chlorate and Shellacby sadeyedangel143 views
A few questions.
1:If you mix the chemicals together would it give a more consistent color while burning? so it would burn the same color the entire time.
2:the alcohol burns blue, so is there a reason you added salt too?
3:Are the chemicals in this harmful if inhaled?
4:Does this burn hotter, the same, or a lower temp then a normal yellow wood fire?
Hope to hear back, and thank you very much for the tutorial.

@panheadTFK That's a lot of questions! 1) I did mix the colors, sort of. 2) I added the salts because I wanted a purple flame, not a blue flame. 3) Depends on the fuel. Methanol, for example, would be toxic. Potassium chloride is non-toxic. Strontium salts are considered safe. 4) Depends on the fuel. Ethanol and isopropanol are, I believe, cooler than a wood campfire. Methanol burns hot. The salts don't burn. However, the flare does contain fuel, in this case sawdust.

What does it smell like???

@aTrueWhiteBoy Really doesn't smell like anything -- it's just an alcohol flame.
