pyrowinner Posted November 15, 2012 Share Posted November 15, 2012 (edited) Bright Streamer.(Very impressive effect,) I used this stars competition formula in my shells. Formula taken from hardts book, Effect: - Bright Streamer Composition in weight: KNO3 29%Charcoal. 34%Ferrotitanium. 25%Sulphur. 6%Dextrin. 6% Screen the ingredients together few times. (I never ballmill above composition) screened comp make a longer tail as well as more glittery effect & get a longer hang time. Pump the stars, damp composition in 75/25 W/A. Use BP-Silicon prime.

californiapyro Posted November 15, 2012 Share Posted November 15, 2012 no wonder it's bright, it's 25% ferrotitanium! well luckily I have a very loose pyro budget, I will try this one Link to comment Share on other sites More sharing options...
spitfire Posted November 16, 2012 Share Posted November 16, 2012 Will try this one too, although the FeTi is rather high and i like to save it for my kamuro stars Thanks for sharing pyrowinner! Link to comment Share on other sites More sharing options...
pyrowinner Posted November 17, 2012 Author Share Posted November 17, 2012 (edited) Reconsider about Fe/Ti, Ferrotitanium is a mixing of iron and titanium with ratio 60/40, & as we know iron is a cheap. So the ratio of formula is...... KNO3 29%Charcoal. 34%Fe. 15%Ti. 10%Sulphur. 6%Dextrin. 6% I never bought Ferrotitanium but use above formula & Screen the ingredients.

Ferrotitanium effects can never be achieved with simply mixing Fe and Ti. You should have also mentioned to use coated Fe and mesh size of metals (especially Fe) otherwise the composition would be impractical. Link to comment Share on other sites More sharing options...

First both metals mixed well & then screened together with nonmetal composition.oh yes pyro Fe is already coated.

Thanks Mumbles.Next I’ll try for Japanese Kamuro stars from “The_Best_of_Afn_I_I” .from many days I postponed cause of its lengthy & accurate coating procedure.

pyrowinner Posted January 14, 2013 Author Share Posted January 14, 2013 (edited) Nice kamuro effect. Willow stars composition+18% to 25% Fe/Ti or only Ti= 'Nice kamuro ' with the Bright Streamer . Use wet process with Willow stars composition for obtaining better result. Edited January 14, 2013 by pyrowinner Link to comment Share on other sites More sharing options...
Algenco Posted January 14, 2013 Share Posted January 14, 2013 Kamuro is the type of star/effect, Nishiki refers to the appearance of the break.Nishiki was a hairstyle of medium length/shaggy so the stars should droop a bit before burning out Link to comment Share on other sites More sharing options...
pyrowinner Posted January 14, 2013 Author Share Posted January 14, 2013 (edited) "Kamuro is a Japanese word meaning "Boys Haircut" which is what this shell looks like when fully exploded in the air. A dense burst of glittering silver or gold stars which leave a heavy glitter trail and are very shiny in the night's sky." http://www.funtrivia.com/img/i/s_link.gifhttp://en.wikipedia....ireworks#Kamuro Edited January 14, 2013 by pyrowinner Link to comment Share on other sites More sharing options...
AdmiralDonSnider Posted January 15, 2013 Share Posted January 15, 2013 I have rolled this particular Hardt composition for NYE, but have not yet tested so far. Rolling such fuel rich comps is possible even with the western method, but is tedious. Thus I wondered if these stars could simply be pumped using a plate. Does pumping such brocade willow comps have any significant drawbacks compared to (single color) *rolled* stars? Link to comment Share on other sites More sharing options...
Peret Posted January 16, 2013 Share Posted January 16, 2013 That's quite similar to Bleser Blond Streamer, but with much less oxidizer - Blond StreamerKNO3 45Charcoal 29Sulfur 6FeTi 15Dextrin 5 This is a beautiful streamer star but slow burning, with burning fallout reaching the ground more often than not. Reducing the oxidizer can only make that worse, so shoot this one high. Link to comment Share on other sites More sharing options...
pyrowinner Posted January 16, 2013 Author Share Posted January 16, 2013 @AdmiralDonSnider Irrespective of stars are pumped or rolled, necessary height should be given to shells. Because the burn rate of brocade willow comps is too slow. This might cause some glowing particles to fall on the ground. Link to comment Share on other sites More sharing options...
AdmiralDonSnider Posted January 16, 2013 Share Posted January 16, 2013 My concern is whether pumped stars will burn less smoothly than round ones with these comps. I was told so. Link to comment Share on other sites More sharing options...
Algenco Posted January 16, 2013 Share Posted January 16, 2013 good question, wouldn't pumped stars have more surface area and hence burn faster ? I've only rolled this comp and loved it Link to comment Share on other sites More sharing options...
psypuls Posted November 8, 2015 Share Posted November 8, 2015 How would this nishiki kamuro perform with replacing Ti for let's say Magnalium or Aluminium flake, would it still be a good effect and would it even work? Link to comment Share on other sites More sharing options...
psypuls Posted November 9, 2015 Share Posted November 9, 2015 well I replaced the Ti with 20% Mgal 45um, hoping for the best Link to comment Share on other sites More sharing options...
Mumbles Posted November 9, 2015 Share Posted November 9, 2015 Let us know what happens. I would expect the effect to be pretty drastically different. Changing both the metal and dramatically altering the particle size could result in something with little resemblance to the original. With a coarse aluminum or MgAl, you will probably get something in the same realm as the original. Going to a fine particle size, we shall see I suppose.

psypuls Posted November 12, 2015 Share Posted November 12, 2015 the effect seem to be cooler than the original, I was lucky the star still works because the star leaves a trail of small sparkles and then explodes into a glowing fiery star due to very high charcoal and fine al content i guess, totally unexpected effect. I am considering priming these stars with BP + Si, but that will make me wait another few days. should I just fire up a shell with plain BP Hulls without booster to try it out first?

psypuls Posted November 13, 2015 Share Posted November 13, 2015 the shell blew blind with no prime on it, have to wait a long time for these stars to dry now because everytime i prime them in the roller they seem to take even longer to dry than the star itself to dry after pumping, broken english Link to comment Share on other sites More sharing options...
psypuls Posted November 17, 2015 Share Posted November 17, 2015 the recipe didn't work well by the way. hardly notice the stars with 20mgal , better luck experimenting next time. Link to comment Share on other sites More sharing options...
