strobo blue

[starlight]

I am trying to make the composition of the blue stroboscope, but I do not succeed to obtain nothing, I obtain only a flame blue-viola. this e' my composition:

 

 

copper sulfate: 180 gr

 

S: 280 gr

 

copper black oxide : 250gr

 

magnalium: 250 gr

 

parlor 180 gr

 

BaNO3: 500 gr

 

KNO3: 70 gr

 

 

you can help me?

 

 

 

other question: you have never used the BaCl2 like agent coloring green in the compositions?

I am trying to make the composition of the blue stroboscope, but I do not succeed to obtain nothing, I obtain only a flame blue-viola. this e' my composition:

I've never seen a blue strobe composition listed. Possibly the strobe type combustion, "vibrational burning" as Shimizu calls it, occurs at too high of a temperature during the flash phase, and prevents blue spectra.

 

I have seen a decent purple though, so, it may be possible. That comp used a different oxidizer though.

[Frozentech]

I did a little more research and came up with this, from Studies on Strobe Light Pyrotechnic Compositions by Takeo Shimizu (Pyrotechnica VIII).

 

(it must be noted that his studies on strobe are almost exclusively with Mg, he found color production superior compared with MgAl )

 

"The type of composition in Figure. 20 (CuSO4 color imparter) cannot be used in practice because magnesium and copper sulfate react violently in the presence of water. The data are presented here only for reference, and because the author's study on sulfate type compositions began from a chance observation of of a copper sulfate type mixture. One day I was experimenting with ignition of various mixtures, when a mixture containing copper sulfate suddenly blinked, thus beginning the present research. Blue strobe light compositions for practical use, however, have not yet been found."

 

So.... use caution working with CuSO4 and Mg.

 

Figure 20, is a triangle diagram showing basically, that most ratios of fuels and oxidizers burned steadily, had poor color, or blinked poorly.

It was only an attempt for being able to realize it, even if the temperature of combustion e' elevated the PHANTOM OF the BLUE PRODUCES IT, WOULD HAVE TO SUCCEED TO MAKE TO GENERATE the INTERMITTENZA. WHICH FORMULA YOU HAVE OF THE PURPLE STROBOSCOPE?

[starlight]

I DO NOT SUCCEED TO BUY THE BOOK OF TAKEO SHIMIZU NOT EVEN ON AMAZON.COM

Here you go, it's not cheap.

Shimizu - The art and science or whatever it's called

I've never succeeded with a blue strobe formula, they just strobe white when they strobe at all. Steer clear of the GE Silicone II formula, it doesn't strobe at all, but it is messy in every way.

Well, keep looking. I bought my copy on eBay for $65.

 

One thing I forgot. There *is* a blue strobe rocket comp that works, but everyone who makes it seems to never want to mess with it again. It uses silicone rubber adhesive as the binder. ( GE Silicone II brand in the US ) *Maybe* if it were made into cut stars you could get a decent blue strobe ? Anyone here try that before ?

[cplmac]

Ha ha, I'm just gonna assume you didn't read my post...

The GE Silicone II formula makes a somewhat decent blue, but it does not strobe at all. The stuff is messy, smelly and not fun in any way. Oh, I forgot, you can't press it, so it's no good for strobe rockets either. It is rubber, and returns to it's original dimensions the moment you take the pressure off the tooling.

[optimus]

I quite enjoy making GE Silicone stars actually I've made a few strobe pots that worked reasonably well too.

 

Starlight, that formula you posted looks odd for a strobe - what is the source?

 

There are a lot of blue strobe formulas HERE.

 

See HERE also.

I didn't read that until after I replied, no

 

I have seen videos of the blue strobe rockets in action, strobing and making a nice rude farting noise as they rose straight up. I've seen other vids of them strobing as they shot across the ground at 100 mph ! In both cases, a nice blue strobe though.

 

Either way, an awful lot of trouble for questionable and hard to achieve results

[starlight]

e' state only an attempt, I cannot reperire AP, and also like material e' much unstable one once miscellato with other substances

[hst45]

Huh? My Anglish is mush confussed, but I'm dooing betr to tell what is it I asking to tell u.

 

O.K., sorry, that was a cheap shot, but you've got to communicate what it is you're asking. Or perhaps telling; I can't say for sure. No one is demanding perfect King's English, and I'm the last one to bitch about punctuation or spelling, but WTF are you trying to say? We deal with potentially hazardous materials, and even a small misunderstanding can have catastrophic results, so a higher degree of communication skills is necessary. That sentence makes less sense than John McCain in a flak vest, surrounded by a battalion of Marines, covered by two Blackhawk helicopters telling everyone how calm and peaceful it is in the streets of Baghdad. Sorry to be a pain in the ass, I just hope that either English isn't your native tongue, or you're higher than a fruit-bat on mescaline.

 

End of self-absorbed bitchy rant, with apologies to all.

....

You have...! What Composition exactlly did you use? I've tried making a blue strobe using GE Silicone last summer and I couldn't get it to work . Here is where I explained everything I did and the formula I used (probably not the same) and I never got it to work! Optimus PM me because I don't want to take up another thread .

I'm gonna do my best to translate this sentence, I actually think I get it.

Gonna try to say this, I can't get AP, and it's to unstable once you mix it with other stuff.

 

P.S.

Thanks optimus! I read through those and there are several I have not tried.

[starlight]

who of you has never felt to speak about the glitter red, and green, she seems to have read that the glitter red she is obtained with ossalato of lithium, someone to me of you knows something? scusattemi for my little corrected English

[optimus]

From what I can remember, Lithium/Strontium Oxalates can be used to make a poor 'pinkish' glitter, but whether the colour is actually percieved as red is debatable. I've never seen one myself so cannot comment further.

[starlight]

you read this article, solo that e' in Italian :

 

realizzare tremolanti colorati.

Infatti, OGLESBY,per quanto riguarda il

tremolante rosso,parla di impiegare l'ossalato

di litio.

donatore di ioni di litio nella combustione

capace di legarsi a queste "gocce" di alluminio

esplodenti.Personalmente io ho ottenuto

un interessante tremolante rosso nel

'93,il problema è l'alta velenosità dell'ossalato

di litio e il suo costo elevato.

OGLESBY scrive di aver raggiunto anche

il tremolante verde con composti chimici

del tallio,un potentissimo veleno sfortunatamente.

E' addirittura la pietra filosofale dei pirotecnici

il meraviglioso tremolante

blu.Stando alle sue dichiarazioni degne di

molta considerazione i composti chimici

dell'indio,un metallo di recente

scoperta,miscelati con il polverino e il trisolfuro

di antimonio provocherebbero flash

azzurri;su questo però è nata una disputa

con il suo collega americano CLIVE JENNINGS

WHITE,che ritiene l'indio inefficace:

vinca il migliore!!!

Here's a very crapy translation for those that don't know Italian:

 

To realize colorings quivering. In fact, OGLESBY, for how much pertains the quivering red, talks about to employ the ossalato of litio. Donor of ionian

of litio in the capable combustion of to bind itself to these "drops" of aluminum exploding. Personally I obtained an interesting quivering red in the

‘93,il problem is the high poisonousness of the ossalato of litio and its cost raised. OGLESBY writes to have reached also the quivering green with

chemical compounds of the thallium, a very powerful venom unlucky. And 'absolutely the stone filosofale of the pirotecnici the wonderful one quivering

dark blue. Being at its worthy declarations of much consideration the chemical compounds dell' Indian, a metal of recent discovery, mixed with the

polverino and the trisolfuro of antimonio I would provoke blue flash; on this however a quarrel was born with its connects American CLIVE JENNINGS WHITE,

that retains the ineffective Indian: Win the better!!!

I cleaned it up a bit with fixing of the chemical names.
