JOPETES, in your formula of monocapa prime, you use black iron oxide,

but could be replaced by red iron oxide, which is a chemical easier to acquire?

Black and red both work fine (great actually).

+1

 

I've also used the red and it does work.

For the non Spanish speakers here (like myself) here is a translation of the original post:

 

"Hello everyone. If anyone has a problem with the formulas of the pdf or Prime star I can help, it will be a pleasure.

 

also please contact me to my email jopetes@terra.com."

 

Edit: @Jopetes: La traducción estuvo bien. (Your translation was fine.)

Stibium,

You can also use red iron oxide, it works very similar.

you can use in place of its silicon. These components have very similar functions, is to train a little slag to facilitate ignition of the star. much of the heat is provided by KClO4 and magnalium. sulfur and especially light charcoal (willow, poplar or poplar, maple, balsa) facilitate the ignition of the monolayer at high speed.

 

You can replace the magnalium by German quality black aluminum 2 micron and add to formula 1 % boric acid. with black aluminum works a little better that facilitates ignition of the monolayer at high speed because the German black aluminum is very thin.

 

I apologize for the translations in English , I used the google translator.

When I did the Google translate it did say blue but I was not sure for how long the Spanish word was. So my next question is it the color blue or does it meen something else

In this document Empavonado means coat or layer. So he is talking about first layer of prime, second layer of prime.

 

Capa means layer or coating. So monocapa means Single Layer. That particular prime is a single layer prime and does not need either a transition layer of hot prime under it OR a layer of rough powder or igniter on top of it.

Hola jopes

 

Thank you for sharing the .pdf great work.

Have you a chart how many apertura you use for different shell size?

Thank you for the information

Thank you very much Jopetes :) I´ve heard a lot of positive comments regarding your formulas, can´t wait to try them out!

That's how i understand this too. But does it really function that way?

A little unmilled BP on top wont hurt anyway, but would this prime really light without it?

It does. Had some blue parlon stars using monocapa only and could see the prime burning as they left the star gun. Problem I had was not applying a thick enough coat of the monocapa and some stars tested blind. After rolling a thicker layer, no problems getting them to ignite.

Interesting. And how thick does the prime need to be?

I find this prime to burn extremely slowly, is that normal? At least when compared with other perchlorate primes.

 

Wont that be blown out when broken hard? Slow burning mixes often do that.

I push the star gun pretty hard while testing these stars and like I mentioned, could actually see the thinner layer of monocapa burn around the star as it rose in the air. So yes, I would say a slower burn but much hotter burn. I've been putting 1/32 to 1/16 layer on the parlon blues. Pretty thick but it works.

Sorry if this has been covered before:

 

I want to make a few blue bengal fires and tend to use Azul 1 or Azul 2.

 

How do these two differ in burning behaviour?

If phenolic resin is at hand - would these stars rather benefit from it or not?
