Hi,
Does anyone know "ricardo caballer sueca 2009 part 1" ?
http://video.google....120479425147688
(maybe you have to shut down the "HD" on your right to download faster).

I would like to know how to create gold to silver effect .
There are lots of these shells in this video (at 2 minutes ).
In fact, what kind of gold and what kind of silver can i use in order to create this effect ?

And how can i do the effect that you can see at about 3 minutes 36 secondes ? (gold)

Beautiful fireworks, right ?
Sorry for my bad english .. and thank's
bye

Hi there, I'm no expert by far but would say they are rolled stars with a high charcoal content comp on the outside (something as simple as tiger tail ), and in the middle a comp a little more complex like a shimizu brilliant core http://www.pyroguide...le=Silver_Stars . Be very careful of you're comps before rolling together ie; chlorates and percs and sulphurs. I know not everybody is daft but a little reminder does'nt hurt. Hope this helps.

horseshoe is essentially an effect where the stars droop whereas a chrysanthemum is a spherical bust cumulating there.

If you're considering using these long burn time and hang time stars in shells as small as 3", I'd use a reactive charcoal if I were you, and be sure to mill the non metal/coarse ingredients. I had stuff hitting the ground with slow gold from an 8" shell. Commercial charcoal can really hang up there. I also should mention I replaced half of the Ti with coarse flake Al. The camera didn't pick it up, but it continued to twinkle for over 30 seconds, and the stars burned for around 5-6 seconds as 3/4" cut cubes.

Mumbles, what you are saying is certainly correct, but it can also go the other way! I've had slow hold burn too fast.

Those are 20mm pumped stars, slow gold. Despite the guy with the camera prematurely stopping recording (what use is all that titanium when no one films the hang time?) I can assure you that they burned out at or just after the end of that video.

True to what you said, they used fairly fast burning pinus radiata charcoal, and the mix had been ball milled (without Ti).

Fflash, I can fully understand your confusion about names. Sometimes a name has several meanings, or several meanings have one name!. To add further confusion, here on the free internet, people keep using names incorrectly! My understanding of the name "chrysanthemum" is that it's one where there are several things with that one name.

It is the name of a group of flowering plants, Which the fireworks are named after.

It is a generic name for stars with tails of sparks.

It is a generic name for warimono shells (round shells with round bursts), that have streamer stars.

It is part of a name of shells that change from a streamer to a different star (say, red), which have a round burst. This shell would be called a "red chrysanthemum". If the chrysanthemum bit burned long enough for the stars to droop a bit before going red, it would be called a "ruby diadem", but probably still a red chrysanthemum! See, having tried to answer you, I've probably confused you!

I have heard of 'chrysanthemum' being used to refer just to faster burning streamers, but not exclusively.

To all you out there, if I've been inacurate here, please point it out to stop the previously mentioned misuse of names spreading farther!

Phill, I think you mean horsetail, but now I'm keen to invent a horseshoe shell!

Citron Vert, Deano is correct. I would agree with the first composition (gold) being similar to tigertail. The silver is probably Potassium perchlorate and Aluminium (because it is bright, and cheap compared more effective alternatives). Black powder with Titanium added would probably give a superior effect, and black powder with 20% Aluminium being inferior, but the cheapest.

Same here, It linked to my youtube account as well.

[CCH Concepts]

for a second i was so happy with myself, thought someone had liked one of my videos as a example of how to do something. was a bit confused when i watched it back as it wasn't a very impressive shell, only had 3 stars lol.

[seymour]

Ok... I must have posted a link that takes you to your own youtube account... I quite like the way that it can make everyone think I am referencing them, but sorry, I was not!

Should be fixed now... Please tell me if it's not!

[CCH Concepts]

makes alot more sense than my vid, wasn't to impressive. lol
