Veline

I haven't tried the Veline colors and have crappy internet so can't download a video (please use YouTube) but can tell you that blues always burn slower because they have to burn cooler. I caught hell trying to time the burn of blue gerbs to match the other colors.

Because of the mgnal. Use a coarser mesh mgnal or use 5% less of what your using. Once you got it nice you can then replace that with 2% sulfur increments until it lights easy again. Veline blue is too bright by the book.

I'm sure it's not the MgAl because all the other comps (except for the green) use the same amount of MgAl and they burn at a normal rate. Does it have to do with the copper oxide and potassium perch?

You might try Hardt's Sulfur Blue if you have copper oxychloride. The dechlorane can be replaced with saran and I've had decent results with Parlon though the saran was much better. I'm currently experimenting with various blues and purples and am learning how hard they are to get right.

Veline blue is a good blue. Predicting burn rate by burning powdered comp on the ground is not an accurate way of doing this. There are too many variables. Roll, or cut the stars, prime them properly, and test them out of a star gun. That is how to determine burn speed. I don't use veline colors anymore, but I did at one time.. and I was impressed with them. I like the system of using similar chemicals, and I like the colors. They are beautiful in the sky. Blues in general are a pain anyways.. but ouf of all the blues I have tried, I like spanish blue, pyro science blue, and veline blue best. And from what I remember of the veline comps, they all had a similar burn rate once made into stars. Stick with the veline blue, you will like it.

brad i'm torn between the spanish blue #1 and the pyro science blue. i have seen videos of your spanish blue shells and my own pyro science blue in mines. which is your favorite? the pyro science is a much simpler formula but i also like the enhancing properties of hexamine.

Hey Roger! I like the spanish blue for 1 reason.... it burns faster. The pyro science blue was way too slow for me, compared to all of my other comps. The 2 are very similar. I use all of the spanish colors for the same reason that some folks use all the Veline colors. They all use the same chemicals, and have basically the same burn rates. Am I dreaming when I think that you were using some AP blues for awhile? Were those not superior to perc blues?? Also don't know if you heard, but I got hired to shoot the fireworks display in my city (Anna). I am siked! :)

Wow! That must be uncomfortable!

Dang Lloyd, you are crushing my dreams!! :) I refuse to be a stream that dries up in summer. I am a raging river my friend! And I am about to shoot my first public show for the city! Been watching this display since I was 4 years old. I can't wait!! Can't hardly sleep!

wow brad that is incredible! pretty jealous over here man. but i've been following your work for years so i can't say i'm surprised. you have definitely displayed the dedication and i really believe you deserve it.

 

no lie those spanish blue burn fast. i just uploaded a mine test of em on my thread. may have to run a test on the pyro science blue for a slower burn to match my red and green.

Roger im betting the PSB will burn at the rate you are looking for. One thing I like about the switch to phenolic, is that although the burn speed increased in my color comps, they also burn brighter. Makes sense, has to dissipate the same amount of energy but in a shorter time. So I dropped the size of all my stars down by 2mm, then increased boost so that they are moving faster, thus covering more distance before burn out. The result is a break that reminds me of japanese shells. Fast moving stars and a big break. I can dig it! I only do this with color shells. I dont use much booster with glitters and charcoal streamers. And thanks for the compliment pal! I was surprised and happy to find out that I can legally take the shells I have made and shoot them at the city display, as long as i dont charge for them. The bulk of the show is on the city's dime, but I do want to shoot about 60 of my own shells. The company that was slated to shoot the show lost their license a week ago, and put the city in a bind. The Mayor called me, because every year he watches my display from his house in town. Hopefully I will be shooting it every year from now on. Gonna go ahead and get my type 54 after the 4th, will make things easier in the future.

Veline is a super system of colours that can be chemically mixed to produce mixed colours. Maybe it would be hard to produce a system that all burned at the same rate while still being compatible with each other.

No I wouldn't change the copper oxide or the perc to turn the brightness down as doing so would diminish what blue is visible. Reducing the metal and replacing with organic fuel will lower the brightness and deepen the blue. As Brad stated you have to test your changes with a couple finished stars to get it tuned up like this. Making the mistake of wasting an entire batch of comp on an untested change is not a happy moment. It's worth the little bit of work to tune it to your liking and ending up with a nice custom comp you can make and rely on. Early on Mumbles got me on the right track with a nice organic deep blue that I worked in some 3 micron alum to brighten it a little and when compared to veline blue by the book, the veline looked like baby blue due to the excessive brightness. I made the changes I talked about above to get the veline a proper deeper blue with a touch of that "electric" shine from the larger mesh magnal pins.

I normally save these tricks for my own personal stash, but you can use potassium benzoate as sort of an "organic metal". I bet if you replaced the MgAl in veline with it you'd see an improvement. It speeds up burn rates and brightens colors without as much washing out as using a metal might.
