Pretty green flame Posted August 10, 2006 Posted August 10, 2006 One question. I can get the cheap ass 0-100micron aluminium (spherical), could i use this in D1 and still get a similar effect or does the aluminium have to be a specific size?
al93535 Posted August 10, 2006 Posted August 10, 2006 20-60 or so micron, atomized aluminum is ideal for this glitter. So I think what you can get, would be perfect!
weknowpyro Posted October 17, 2006 Posted October 17, 2006 Everytime i have made D1 glitters, my stars have been extremely crumbly. I am using dextrin and i do mix in water with the comp to help pump these stars. I am stumped on this, any ideas?Thanks
Mumbles Posted October 17, 2006 Posted October 17, 2006 How are you pressing them? If you are using low amounts of water(say less that 8%), you really need to compress them well, such as with an arbor press, or some other sort of press. It also depends on how large of stars/comets you are pressing. If you are using high amounts of water, the binder may be leaching out. Honestly, the most probable answer is that it isn't dry yet. Damp stars, and EXPECIALLY driven in stars are not firm at all.
deadman Posted May 9, 2007 Posted May 9, 2007 I know this thread has been dead for a while, but I want to put this out there for others that haven't done D1 before. I used 6% water (well 75/25 H2O/Alcohol) by mixing the comp and water in a container as much as possible. Of course this just resulted in lumps. I then forced the "wet" comp through a windows screen several times. The moisture was spread evenly after about the 3rd time. I used a homemade ½" star pump. After loading the pump each time I gave it a decent whack with a deadblow and popped them out. I dried for 5 days and these have been the hardest stars I've ever made. I plan on uploading a video of a mine or shell with these as soon as I take one. 1
tentacles Posted May 10, 2007 Posted May 10, 2007 it's funny, I saw the D1 glitter mentioned all over, and looked all over for the formula (even here) and must have just passed it over Thanks for the bump!
crazyboy25 Posted May 28, 2007 Posted May 28, 2007 i have a question eveyone is saying how ballmilling D1 glitter deystroys the effect i am assuming this is becasue it crushes the aluminum. couldn't you ballmill all the components exept the aluminum then sieve the aluminum in without deystroing the effect?
Mumbles Posted May 28, 2007 Posted May 28, 2007 You never ball mill comps with metal. It destroys the effect because it burns too fast if you will. You want it to burn a little slaggy. The slag is what causes the glitter effect. 1
crazyboy25 Posted May 30, 2007 Posted May 30, 2007 i got a question:i know D1 glitter is easy to ignite but do you prime it? according to united nuclear stars with only potassium nitrate should be primed with a 1mm meal prime i was planing on doing this by rolling my stars untill they are 1/2" diameter let them dry for 20 minutes then spray them with water and roll them in meal powder would this be an acceptable way to prime them?
pudidotdk Posted May 30, 2007 Posted May 30, 2007 D1 ignites pretty easy. It isn't really neccesary to prime them, but if you are afraid they won't light, a bit of prime won't hurt. 1
qwezxc12 Posted May 31, 2007 Posted May 31, 2007 I've never primed them in either mines or aerial shells. In mines, I pipe the quickmatch into the stars - they ignite lighting the lift in turn. Here's a 3in mine w/D1 and FF#3 stars: Mine In aerial shells I've used 3/8" pumped in 3in ball shells. Burst was 4:1 KP on crispies with ~3g whistle boost: 3in D1 Glitter shell
crazyboy25 Posted June 17, 2007 Posted June 17, 2007 rooster said he rolled his stars without deystroying the effect so that is what i will do becasue i prefer rolling. would it be ok if i used 75/25 rubbing alcohol to water as solvent? i realize too much solvent could ruin the effect so i would use it sparingly does this sound ok?
blaadjes Posted July 8, 2007 Posted July 8, 2007 Question: Is D1-Glitter often used in professional shows? Yesterday I saw similar effects in a show, so I was wondering if they used the same composition. It was a big break with a cloud of golden sparks, then it changed in to tiny tingling silver/white sort like strobe effect, slowly falling into the sea. Here's a video of it, the quality is poor, so mby hard to see.
asilentbob Posted July 8, 2007 Posted July 8, 2007 Wow thats a really really long delay glitter... And no, D1 isn't likely to be used in pro shows. As i understand it all of the glitters used in pro shows use pre-made meal powder as a feed stock, then adding aluminum or magnalium, antimony trisulfide, strontium carbonate, sulfur, charcoal, etc. Winokur's compositions and other glitter compositions may be "translated" over into a formula based on meal powder that has a similar effect... then they might be used commercially.
crazyboy25 Posted July 8, 2007 Posted July 8, 2007 that was nice it kinda reminds me of something i saw they looked like large canister shells at least 5 of em were shot up and had huge orange waterfalls that lasted a LONG LONG time. no flashing though so i suppose it isn't glitter. im curious to know hat it was sorry no vid.
crazyboy25 Posted July 9, 2007 Posted July 9, 2007 That looks more like strobe than a glitter. no i don't think so strobes flash as they go but don't leave a flashing trail these had trail that continued to burn after the star was gone.
pudidotdk Posted July 9, 2007 Posted July 9, 2007 That's strobe for sure.The trail is either a prime or a streamer before the strobe.
Mardec Posted July 9, 2007 Posted July 9, 2007 I agree, that are some slow ass stobe stars, not glitter!
blaadjes Posted July 10, 2007 Posted July 10, 2007 But if you take a look at the video from qwezxc12 with his D1-glitter, you'll see something like the same effect, so I was wondering, why does that Alu visualy reacts the same way as a strobe effect..? Cheers.
Mumbles Posted July 11, 2007 Posted July 11, 2007 I see where you get the idea from, but those were definatly strobe cores. You may notice that the strobing kept falling and expanding, and burn out at roughly the same time , while in CPL's video they were in the tail of the stars, and burnt out at random intervals. Additional point being, those were red strobes, and red glitters do not exist truely to my knowledge. The effect is just from a long delay on the glitter effect.
qwezxc12 Posted March 28, 2008 Posted March 28, 2008 Videos showing the differing effects of Al size and oxidizer mesh: 6in D1 glitter shells using 5um spherical Aluminum and finely milled KNO3 6in Di glitter shell using 25-30um spherical Aluminum and more granular KNO3 Those two 5um shells were D1, not white strobe...I liked the effect - I plan on using 1/4" stars as cores for color changing shells.
hst45 Posted March 29, 2008 Posted March 29, 2008 qwezxc12, I've had the same impression: the type of Al you use can make D1 totally different. I've been using 80-325 mesh spheroidal lately (Skylighter). This seems to give a longer series of flashes which I like. 325 flake is good too, but different. Different KNO3 mesh? Damned, more experiments.....what we'll do for science...... The few, the proud, the pyros....
qwezxc12 Posted March 29, 2008 Posted March 29, 2008 The two batches weren't an attempt to be scientific in the least...too many variables changed at once. The KNO3 was powdered in my ballmill to talc consistency in the two shells with the 5um Al; the other shell with the larger Al used it right from the bag - about the consistency of salt. I'm sure the stars with that were drossier when burning.
hst45 Posted March 29, 2008 Posted March 29, 2008 The two batches weren't an attempt to be scientific in the least...too many variables changed at once....I know the feeling. I do the same thing; I'm out of one particular mesh/species of charcoal so I substitute what's on hand, I use a different KNO3, I change the moisture in my rolling of the stars, I dry them more/less, and they are SPECTACULAR. O.K., what made the difference??????? Never to be duplicated again....(damn it!) By the way, when are you going to get to the Granite State? Bike week?
