what's wrong with orange flames?Can I have a chicken Cantus?
Or indeed a normal Cantus....

What would you want a Cantus for? I can't imagine anyone wanting one

you know how when you fold an orange peeel so it's the orange side out stuff spays out of it that makes your eyes sting? try holding a lighter up to the spray. especially when it's dark!

Boric Acid in Methylated Spirits works fine. You have to keep the spin speed down a little as it is weaker than Sol T etc.. try using shorter staffs or poi for it.
http://www.geocities.com/firepoi/index_css.html advises Pottasium Chlorate is a possibility for purple flames. Dont waste your money, i have and it dsoesn't work. Have tried it with Meth and Sol T, No luck. Any advice on other fuel bases to try it with now that i have 25kg of it?
Would be much interested in the results of the Pottasium Permagate.

Potassium Permangenate works for purple but even better is Potassium Nitrate (which is a bit harder to get a hold of). It produces a much brighter purple.

My friends work at the chemisty labs for one of the universities here. Not sure if they sell it retail in stores or not. Sorry. NYC would probably know the answer to that one though.

Sorry dude, I've said it a few times before. My suppliers only sell to schools, they get tax breaks and stuff. Search the internet to find a chemical supplier that will sell to you. That'd be my best advise...

Right, well after reading this all..
Potassium Nitrate is an oxidizer. You can get it at you local store in the pharmacy, it's often sold under the name saltpetre. I often used to make smoke bombs out of the stuff... This stuff is a POWERFUL oxidizer (also has some undesirable side effects men, so don't eat it.. if you know what i mean ;P )But, when mixed with a fuel (I would use sugar for the smoke bombs in a 3:1 ratio) it burns with a bright purple blue flame that's kinda smattered with orange bits (looks neat) that's very hard to put out. You can also make a super saturated solution and soak cotton string in it to make slow burning wicks. The only drawback i can forsee in using it for firespinning is this, it burns VERY hot.. like i said strong oxidizer. Although not as powerful an oxidizer as Potassium Perchlorate (never used that outside a lab myself...), it is also much safer, being much less sensitive to static charge and friction. Can spontaneously ignite if a mixture containing it and Aluminum powder becomes wet (known as the "Aluminum/Nitrate Reaction"). Be careful playing with the stuff. -orin PS: do NOT under ANY circumstances use a potassium nitrate mixture in any way that it could come under pressure... simply put.. oxidizer + fire + pressure = BIG boom. PPS: in case you don't know what an oxidizer is... Oxidizers are chemicals that release oxygen when they are heated, or during the burning process. Generally, they are not flammable themselves, but when mixed with a fuel (such as Sulfur or Aluminum, for example), they promote rapid & vigorous burning when ignited Play with fire, but play safe.

what would be a good fuel base for that? petrols, or meths?cause i got the saltpeter... i just dont want to waste it. [This message has been edited by phuzzz (edited 15 December 2001).]

Phuzz: Potassium Nitrate is virtually insoluble in methanol.
As for petrol (gasoline I'm assuming) I'm not positive.. never tried...Don't mix with diesel... again.. boom.. :\ I know that it's extremely soluble in water however, so lacing ones wicks (I'd do a test with towel wicks first) may work. Also.. you said you didn't want to waste your supply... well I wouldn't worry about that, it's relatively easy to obtain.. You can usually get three kinds.. Chemical Grade, Fertilizer and Stump Remover.. most people can't get the Chemical grade.. which is essentially the same as medical saltpetre. Fertilizer grade, typically consisting of 98-99% potassium nitrate. Sold as inexpensive 14-0-45 fertilizer. Used to increase nitrate levels in soils... Stump-remover.
Sometimes you can find KN03 in products used to accelerate the decomposition of tree stumps. The amount of potassium nitrate present in this product will vary from brand to brand... but i really suggest against using this... due to additives the companies may add.. pesticides/herbicides.. poisions and other icky stuff :\ -Orin

I tried pure potassium sulfate with towel wicks and denatured alcohol. It changed the color of my flame to an orangish-pinkish tone. Most people said it looked a lot like a toasted marsh mellow! No purple though very disappointing! I am about to try table salt NaCl.....does anyone know if this will work (other than theoretically) for bright yellow?
Love ![[Wink]](/ubbthreads/images/icons/wink.gif) ,
Laura (aka hairsmythe)
BTW My towel wicks which I made with home depot terry towels and the instructions found on this site worked fabulously....I have to say the flame was bigger and brighter (however toasted marsh mellow) than all of my friends kevlar wicks. Held together really well and I think the life was prolonged because I snuffed them out with a wet towel!

Morning all,
Lithium Chloride does a nice burgandy colour but it's a little hard to get hold of - it's an anti-depressant. Cupric chloride does a nice strong green. I usually make saturated solutions in methylated spirits with both of these to soak my wicks in. The bonus is that after they're dry, I can use kero and still get the colour. The colour lasts about 15 hours (no idea how many burns).
Potassium nitrate is soluble in water. I'd suggest making up the solution, soaking your wicks and letting them dry. The wick should absorb the salt making it possible to use your fuel of choice when you light up.

Has anyone tried making a paste, perhaps petroleum jelly + salt of your choice, and smearing on top end of your poi? Centrifugal force should keep it from flying off an sticking to someone. That would be a bad thing - would be a bit like napalm I imagine. If its on the top [inside of swing]. Havent really graduated to flame yet, so I havent tried this idea.

I've said it before, and I'll say it again.
It's all based on the physics of flame tests, that you did at school in chemistry.
http://chemistry.allinfoabout.com/features/flametest.html
This has a list of salts, and the "colour active" component. Most of these salts won't dissolve in anything but water though. That's your major problem with salts; they need polar solvents to dissociate and dissolve, and methanol just ain't polar enough. Petrol, parrafin and diesel are useless for this.

The only problem I've run into with colored flames is the fact that all chemicals that alter the color release fumes much more toxic than typical fuel smoke. Use with caution my friends.
The chemistry here is fairly sound, if a bit overly complex. While hydrogen bonding is present, for example, it is an extraordinarily weak bond. It could not prevent combustion.
Those using lower temperature fuels like lamp oil/kerosene, realize that certain color changing chemicals require a high amount of energy in order to excite electrons to the higher shells to release color. Green is more standard than other colors because it's activation energy is lower. Some colors will only be visible with white gas, which burns at a higher temperature.
Good luck for now; if I can get some work out of the way, I might be able to review a few articles and see if I can't find some harder numbers for everyone.

I said it again because it was quicker than finding the original post I posted it too, and I personally am not a fan of having to click link after link to get to a useful post.
It's all about personal preference really.

hmmmmmmmm i may be off topic here but i remember putting pottasium permanganate into a flame with some very nice coloured flames as a result.
i don't know if there any chemical restrictions on this substance or not but would like to know
