Flash to bp conversions

[DontBlink]

Hello Again

 

I found some receipes on This Wiki.

I`d like to make a slower red for this instance.

Is there a drawback to taking the Kclo4 and Magnalium out, and adding the BP instead?

 

• Potassium Perchlorate 106.0 g
  
• Strontium Carbonate 28.0 g
  
• Magnalium 12.0 g
  
• Parlon 28.0 g
  
• Dextrin 8.0 g
  
• Red Gum 18.0 g
  

Greets Luk.

Yes there is. Mainly the fact that it won't be colored, and will probably barely burn.

Posted in the right spot

Sow it`s the heat thats essential in the reaction?

Ae "filtering" whites.

 

Btw Forgive me for asking these basic questions, im really new.

Got a lot of nice ideas, only recently the room to store some chems.

Tx for helping me out here!

Since Im going to mix up some flash.

I always wondered.. If you put it loosely in a cardboard tube,

and shake it (for a long time).. would it ignite itself?

[Mumbles]

I'm not exactly sure what you're asking in the first reply.

 

There are several problems with replacing the KClO4 and MgAl:

 

1. The mix won't get hot enough. A certain amount of heat is required to excite the color producing species.

 

2. Black powder is pretty balanced as far as oxygen and all that goes. The KClO4 in the above mix is in excess to provide oxygen to the other components.

 

3. All the charcoal would over power the colors.

 

 

To answer the question about removing the white light. When MgAl burns, it makes MgO and Al2O3, which produce a lot of white light. This is prevented by using an excess of the Parlon, which donates chlorine. Besides making SrCl, which is a good red colorant, it also makes MgCl and AlCl3. MgCl and AlCl3 are UV emitters if I remember correctly. This prevents much of the white light from being emitted, and thus improving the color.

 

I would stay away from making any flash for a while.

But NO, don't mix flash like that.

 

Noo never!!

I made it before by making some gram batches mixed with a marter paintbrush.

I gladly pose as absolutely dumb. but im not ignorent.

Im killing issues right now, creating a modular system.

Rather asking stupid things instead of blowing my head (and my budget).

 

Anyway....

To further expand on the subject.

would the mixture be able to generate static as mixture alone (containing Al).

Without the media being conductive (in cartboard as always).

@ mumbles

It`s strange.. and after hearing all the bad things about flash

it`s very understandable.

But I knew no other mix

Im very aware it`s powerfull and fast.. Thats wat I loved for years.

To yust contain it. (i also know the impact sensitivity)

I`d even explain my routine if interested, and you might agree?

 

However..

I`d like to use bp.

That was the intention of my post.

Only I like a little bit of color.. or atleast some crackling effect or sumthin.

 

yes i ment the temps in my 1st post.

But it`s ansered.

 

And thanks for the request as many already!

Dontblink: I don't wanna be rude or anything but Xetap probably gave you the best reply from this topic. You need to do some serious reading. Colours aren't one of the easiest things in pyro. You're asking some very basic questions that don't come from ignorance, they come from not knowing what you're talking about.

 

When Mumbles tells you TWICE that it won't work to replace the KClO4 and MgAl by bp just listen to him. He has a lot more experience than many of us on here. Just look at it as listening to your teacher. When your teacher tells you to do something a certain way you take it for granted because he knows his subject. Same goes for here, certain people know what they're talking about and especially as a newbie don't argue with it.

 

Do some reading, do your homework and then come back with any questions as all I have to say.

 

p.s. Crackling is a very long shot away from bp. Nothing that you'll add to your bp will create any form of crackle. Really course MgAl might give you a tiny bit of a crackle but from a few feet away it will barely be noticable.

[DontBlink]

Brakkie never did I ignore good advise.

It`s a paradox..

 

Im reading a lot, returning here, to fill in the loose ends!

Mumbles and Xetap, really made a difference.

I say the latter about flash and then it`s getting boring.

I was thought mixing flash from an ole friend of my dad about 10 years ago.

im 26 now, never changed a bit.. it`s freakin solid.

 

Im not even ordering stuff, before my list is complete.

I can`t pretend i know shit about BP couse that`s my new angle, really like to learn.

Never assuming I could replace the chems with BP twice.

As you might have read "assuming it`s the high temp creating white, (as in a full

spectrum of the light colors), wich in term can be filtered to different frequency components.

Mumbles confirmed this, and I thanked him.

 

So read read read is what im doing. plz dont say I didn`t!

[DontBlink]

Nah man you yust scared me a little.

It`s an excelent reply!

[DontBlink]

Letme get back on that Xetap.. interesing stuff!

I'd just like to offer, with some MgAl comps you can get a really nice audible sizzle - those 5" flaming shit shells I made for new years' had a great sizzle sound. Like frying bacon. I used about 25% 20-30 mesh, 50% 30-60 and 25% 60-100 mesh Mg/Al.. I think. I have notes at home on the exact ratio.

DontBlink, somewhere back in May of last year, I was where you are now. I've since read Shimizu twice, Tom Perrigan's book more than that, and I've got several other volumes of fireworks and pyrotechnics. I'm working hard at just getting small (2") mortars to function well with charcoal streamers and such. There's SOOOO much to it. Lift. Burst. Timing, priming, shell pasting. You can play with nothing but BP components, red gum, and a few metal salts for years and still just be scratching the surface.

[DontBlink]

I yust love it. .

Timing should be tackeled, think it`s nice to have a cannister shell

with a star/timing thing. (hence the color).

I do have some nice paper, and what we call "waterglas" to play with.

Gives some very nice tubing.

So mainly I see myself test firing, and testing the timing thought.

That`s for burning some stars. (the crackle stuff is an area lovingly explored aswel)

But I do need to know what is what.

Have to make a trip to Belgium one of these day`s and get me some fuses.

Maybe picking up some chemicals..?

They ban everything here, don`t see myself traffic much.
