How To Make Senko Hanabi Sparklers (very rare Japanese fireworks)

Senko Hanabi sparklers are a type of firework I have put significant effort into perfecting since 2007. I used to build large and complex fireworks regularly, but these little sparklers proved more challenging than even large multibreak shells. The effect produced by a tiny drop of dross that forms on the end of the sparkler is very delicate and even a tiny change in the composition or method of construction causes the result to fail. Finally I have found a method that creates consistent results which I demonstrate in this video. Still, there is room for improvement.
Possible changes to the composition include replacing or supplementing the charcoal with soot (commonly called lampblack) or even graphite. My composition shown in this video contains a higher percentage of oxidizer than most documented Senko Hanabi compositions as I rely on the paper wrapping itself to contribute to the fuel mixture in consuming the potassium nitrate. I have tried a wide spread of compositions including more traditional ratios and found this to work best.
It is not well documented what reaction is the cause of the sparks forming and being ejected from the ball of dross on a Senko Hanabi. I suspect it is a reaction between sulfur dioxide produced by the burning sulfur reacting with carbon in the charcoal to form a variety of byproducts that eject yet unreacted carbon out of the drop where it further reacts in the air. Perhaps catalyzed by remaining potassium salts left over by the potassium nitrate. Here is a paper I uncovered about similar reactions: www.mdpi.com/1422-0067/6/1/130...
Here is another written tutorial for Senko Hanabi that you may find useful: bit.ly/2vPQ5VP

Me and my brother made these are few years ago, we got the composition from some Chinese website. I still got the composition saved as a .txt on my old hard drive, it's: 55 potassium nitrate 22.5 sulfur 22.5 charcoal we also made the powdered charcoal ourself, we tested both pine and coconut shell. I would say pine worked better. We also tried to add some icing sugar, the "glob" was bigger tho it seemed like it produced less sparks. For the paper we used brown sandwich wrapping paper. Tissue paper also works but burns faster.

Adding icing sugar adds cornstarch which would slow down the burn rate and less sparks. Generally avoid powdered sugar in pyrotechnics and rocketry.

I've been attempting to perfect Senko Hanabi for about 15 years now. The charcoal is the most important component, I've had some great success with charcoal from pine cones, but only one particular batch worked better than just radiata pine charcoal. Vegetable black from one particular brand of art pigment worked well also. I tried realgar once, not worth the toxicity fears, especially inhalation of the smoke! I use high purity recrystalised potassium nitrate and resublimed sulfur, but it doesn't seem to make any difference compared to fertilizer grades. I've tried many kinds of paper. The crepe of streamers works as you suggest, as does genuine Japanese washi. The best paper I found was a bleached kitchen paper, thin and smoothly calendared. The brand may only be available in Australia, it has a tiger on the wrapper. Haven't tried to find a US substitute yet, still using my original roll. Another paper that was exceptional was that which a particular brand of glass microscope slides were packed in, a sheet between each slide. A little too small for comfortable hand-held sparklers, but really excellent for some reason. Composition wise I use 60:24:16 KNO3:S:C as a starting point.

As a welder, one of the most fascinating and magical parts of the process is having your welding helmet on and seeing the molten metal in the puddle, its like controlling lava. It makes you feel like a wizard to turn a solid piece of metal into a molten puddle. And what you have done with this sparkler, is make that molten puddle completely visible in daylight without being too dangerous. Seeing that ball of slag on the bottom consuming itself is absolutely magical. I love it!!

"what might help?" well all sparkler compositions that i worked with and are similar to BP the amount of sparks and their time of burning off is dependent on the size of the charcoal particles size... grind the charcoal separately, then sift it, use the fine dust for the composition your making and add some of the larger charcoal particles for the sparks... try using ball mill for few hours to grind the composition...
@Nighthawkinlight
@Nighthawkinlight 6 жыл бұрын
These sparklers seem to work independently of charcoal particle size because the composition itself has burned long before the sparks begin to form. I have tried coarse charcoal a number of times just to be sure and it makes no difference.

you are most probably right... i never ever seen this type of sparklers and i dont know how they work... above all when i make compositions with potassium nitrate if they make such droplet it means the composition is not mixed very well (to little time in the ball mill) or there is excess of potassium nitrate, but thats not the case in the sparklers type your making it seems... maybe try to moist the mixture with 50/50 water/alcohol before making the sparkler? btw can you be so kind to tell me what video compression are you using for your videos? i found it strange but some of the channels (crazy russian hacker, slingshot channel... and your channel) upload videos (most likely depends on the video compression) that cant be watched on firefox using the youtube html5 player... this goes for some time and i reported it many times but it seems google doesnt care and forces you to use chrome...

Have you tried monitoring the temperature of the bead of dross with an IR thermometer? Maybe the amount and volatility of the sparks has a relation to the temperature of the reaction taking place and knowing this could help you narrow down to some solutions. If not that I'd suggest brainstorming some independent external testing to compare differences and similarities rather than relying so heavily on what goes into it and then when you've found some of these variances you can work on what goes in. Some other thoughts are timing the reactions so you can arrive at a weight/time assessments, determining cross sectional area of the sparkler prior to lighting vs the final dross, a way to quantify the shape of the sparkler (is the material in a cylinder, tear drop with small side up, tear drop with small side down, etc.)

DeceptiveReptile Yes basically fireworks need to be made by a company and inspected. An individual can't make fireworks even though fortunately we are able to create model rockets.

I had an old fireworks manual, published 1934, which said the best results for senko hanabi were realized using a mixture of particle sizes in the charcoal. Fines insured quick combustion and slag formation, larger particles threw more and bigger sparks. The author speculated that rubbing charcoal fines into the paper beyond the composition mixture would improve the endurance or 'climb' of the slag. Good job, I never got mine to work.

Haha, that's the proper way to title something. Haven't you learned that in school? Only thing he did technically wrong is capitalized "to".

Great to see these on KZbin. I first read about these in Ron Lancaster's book "Fireworks, Principles and Practice" which includes a chapter by Takeo Shimizu describing several compositions and the mechanism of operation.

Thank you so much! you have made me a fan of both your channel and senko hanabi! Very tricky chemistry mine want to flare like flash powder so I tried suppressing the flare with a little sugar, very little, and it seems to work to hold the glob but it sparks less. I still can not thank you enough for your tremendous effort, it has made the learning curve shorter by several years. Just like you I will share my findings and credit you for the insights in this amazing craft.
