Red composition without Red Gum

[pyrosailor99]

Hi all!

 

i would like to make Red stars (or red lances)

 

i have many chems (also strontium nitrate, potassium perch, ... alu and and magals)

i have also shellac and Parlon but i don't have any red gum.

 

in any comp i found over internet Red Gum si required...

 

is there a comp to make red stars and lances that use Strontium Carbonate (not nitrate) and avoid Red Gum??

(for the real i have also strontium nitrate, but as a newbie in colored stars i want to avoid it as i know it is a bit poisonous, i will use it later when i will increase my experience)

 

thanks

Strontium nitrate is about as toxic as table salt there is no need to worry about it.

Redgum can be replaced by other organic fuels or is completely ommited in some metallic formulas, shellac can sometimes be substituted for redgum though it dose not perform as well with perchlorates as it dose chlorates if your making lances and using them imediately powdered sugar is a suitable alternative though it is hydroscopic and will quickly spoil if stored

 

 

[Potassiumchlorate]

Since you have metallic fuels it would probably be possible to use shellac instead, in combination with those, but usually you use shellac only if you have potassium chlorate or, in rare cases, ammonium perchlorate. Potassium perchlorate, strontium carbonate and shellac will probably not burn at all.

Red star #8

Comments: Produce as a cut star

Preparation:

 

Potassium perchlorate.............................70

Strontium carbonate...............................15

Charcoal 150 Mesh.................................11

Dextrin...........................................4

 

my 2 cents...

also, you sure you don't want to use strontium nitrate? i have a whole host of tried and true reds without red gum...

Red gum usually isn't hard to come by, so it may be good to buy some as it is very useful. However look here http://www.thegreenman.me.uk/pfp/db1.html and look for stars and there are a couple of reds listed without red gum. It's probably one of the better web based formularies at he moment.

Hi californiapyro, can potassium chlorate be used instead of perchlorate ?

[pyrojig]

Shimizu and Hardt can provide chlorate formulas for Chlorate reds ? which are very easy to make , and I believe that Strontium Carb can be used .

Strontium nitrate is not toxic... or rather, not any more toxic than any other chemicals you use in pyro. Barium Nitrate (for green) is a little more toxic than most other chemicals, but still safe if you have a respirator. Strontium nitrate can be challenging to use if it is humid outside, because it is hygroscopic.. but on the other hand, the brightest and best red colors come from using Strontium Nitrate, in my opinion.
