Any possible blue composition without perc

[pyrodoc]

Hi

We don't have chlorate and kp allowed in our country. I have heard Hexamine and potassium bromate being used to produce blue.

Any possible composition in the absence of perc and chlorate.

The composition database section is for tried and tested formulas. I moved it to a more appropriate section.

Dangerous. Bromate strong oxidant. It oxidizes organic substances if there is water.

[pyrodoc]

Niladmirari, you have a pm.

[taiwanluthiers]

You can easily make chlorate if you got potassium chloride, a titanium plate, and a MMO anode. But if that's illegal then it's hard to say...

[Niladmirari]

I did the stars KBrO3 + fuel and Ba(BrO3)2 + fuel.

I saw that over time, changing the color surface of the star, and they started to smell. The oxidative reduction reaction.

Hexamine hygroscopic. It always contains an admixture of water.

[Niladmirari]

Combustion (burning). Close the color of normal combustion. But the distance it looks like a blue dot. No brightness.

Is KP legally not allowed? There might be some old formulations involving Calomel(Hg2Cl2) for blues but can't remember if thats free of KC. Have a look at the databases. K-Bromate can possibly yield some good color, I once tested some loose composition with KB and Copper Sulfate(I had very limited quantity of KB as it was quite expensive) the composition emitted a strong smell of Bromine when burnt and one should avoid inhaling bromine at any cost .

 

Swapnil Sutar once shared here a composition without KP/KC and containg Copper(II) Oxide

There are a few nitrate blues out there. I don't have a ready reference, but I remember one being based upon KNO3, and giving a _reasonably_ good blue... it wasn't bright, and it wasn't 'pure', but it was still blue, and had not a smidgen of perc or chlorate in it.

Is KP legally not allowed?

 

Most of Europe (all of EU) has outlawed the private use of "precursors" for high explosives, which includes most, if not all the useful (per)chlorates we use in pyro.

Making it your self, or buying it from an outside source is your only option. However, if you get caught with it, you can get charged with anything from just storage or production of a precursor, to terrorist activity. With todays "terrorist alert" levels going up everywhere, i suppose the risks involved with owning or making the stuff is going to increase.

 

Funny thing... If your a organization, you don't even need permits to by the same precursors. But i'm sure potential terrorists are to stupid to file for any sort of legal documentation, other-ways all our lawmakers hassle would be entirely in wain, and our politicians couldn't be THAT stupid... Right? *sigh*

FFS... Someone should read the laws they pass back to them, before they pass them.

 

Best of all. As a hobbyist it turns out you actually can get licensed to make fireworks here in Sweden. There is only one guy who managed to get licensed, but then again, not that many try. The reason being you need the same kind of property you'd need if you were a firework producing a couple of tons of explosive product a week, even if your aiming for 5 kilos a year. And here is the best part. Since your still a private person, there is no exceptions made for explosives precursors, so you still cant legally buy, store, make, or own (per)chlorates.

So now that same fella who got his permit has to go through the hassle of getting a new permit, for a organization, profit, or none-profit, and to top it all of, he now has to file paperwork dealing with the economics of the organization. Well, i guess, as an upside, he can deduct the VAT on shit, as long as he is turning a profit... Oh, right. He never will, it's a hobby.

 

People, i'm sorry. This topic always gets the best of me. I should have quit a long time ago. But i keep needing to get this of my chest.

B!

 

Edit

And how the F*** did i get in to this topic in a thread about blues. Again, Sorry.

Have a research into copper metal blues, they work with nitrate. I have some of thosd stars here. But the worse think isthat i must have thrown the card with the formula ouf during cleaning, if i find it i will post if here.

Do it please man!

Here are some from Skylighter's site:

http://www.skylighter.com/fireworks/how-to-make/copper-green-blue-fireworks-stars.asp

Finally, here are several of the more useable pyrotechnic formulas from Donald Haarmann'sPyrotechnic Formulary (BK0078). This incidentally is what the Formulary is great for: finding pyrotechnic formulas to match a set of ingredients.

Green fireworks star (from Experiments in Developing Green Star Formulas)

Magnesium 1.8 pts Barium nitrate 5.8 pts Copper 0.5 pts Parlon 1.5 pts

Green Fireworks star (from Experiments in Developing Green Star Formulas)

Magnesium 1.0 pts Barium nitrate 5.8 pts Copper 1.3 pts Parlon 1.7 pts

Green Fireworks star (from Experiments in Developing Green Star Formulas)

Magnesium 1.8 pts Barium nitrate 5.8 pts Copper 0.5 pts Parlon 1.5 pts Gilsonite 0.2 pts

Flare Green, MC241

Magnesium 23% Barium nitrate 53% Copper 2% Hexachlorobenzene 20% Gilsonite 2%

I'm not sure whats the granularity of Copper powder tobe used , 200 mesh or finer?

you can try , experiment with cuo, pvcpowder and nc wood lacquer(as a fuel + oxidizer ).now i keep experiment with it.

oops sorry , I wrongly mentioned about green while you asked for blue
