Thanks everyone for coming out to our 2018 Safety Training Seminar held April 21st at Perfect North Slopes in Lawrenceburg Indiana.
More than 40 men and women came out to get first time training or a refresher course in pyrotechnics training.
A special thanks to our instructors for sharing their hands on knowledge about fireworks safety. John Rozzi's contribution and knowledge is unmatched in the industry. I truly appreciate his time and sharing his lifetime of experience. We are fortunate to have him as an instructor.
Martin Shaffer chipped in with his many years of hands on experience. Pat, David, and Eric answered many questions that people had on the Pyro Seeking Digital Firing System. Thanks, guys.
The highlight of the day is always the live shoot where attendees get a chance to hand fire shells. If you didn't make it this year mark down next April. Check our website next year for the exact date.
The Light The Night Walk for the Leukemia and Lymphoma Society in Cincinnati was an inspiring event that Arthur Rozzi Pyrotechnics was proud to be a part of for the second year in a row. It's night of support, celebration and remembrance of those affected by cancer. It was a beautiful evening and we were honored to help the crowd truly light the night on the banks of the Ohio River. The stories, outpouring of support and money raised for research was remarkable. We are always humbled to be included in special days and events and strive to make them as memorable as possible.

Arthur Rozzi Pyrotechnics, Swan Lake
Montreal, Canada 2014
13 years later, my guests will still remark about the incredible fireworks at my wedding!! It's true, we all want our day to be special .... to stand out from every other wedding that our guests have ever been to. The spectacular surprises and touching moments that centered around the stunning pyrotechnics, made my day unique.
Our wedding venue windows were lined with sparkler type effects that erupted when my husband and I cut into our wedding cake. I still remember the look our guests faces when that happened! I was completely surprised as well and it definitely was an incredible moment that I have cherished all of these years.
The highlight, however, was the display towards the end of the evening. It was romantic show, synchronized to my favorite Andrea Bocelli song while surrounded by all of the people that meant the most to us. It was so personalized and such magical moment.
Fireworks or special effects my sound like an extravagance with a large price tag, but Arthur Rozzi Pyrotechnics will work with your budget to add some dazzle to your special day. Contact us to discuss your vision and make it a reality.
Why Shooter School?
Besides being a fun time of getting together with our fellow pyrotechnics friends, an annual shooter training school helps us build upon the skills we need to perform great and safe fireworks displays. Unless we are traveling the world, shooting fireworks displays all year long, many of us just don’t shoot every day. We need a chance to get back into the groove so that this summer season we’ll be primed and ready to set up, choreograph and deliver the best fireworks shows we can.
The State of Ohio only requires that we attend fireworks continuing training once every three years. We know that that just isn’t enough. During training we brush up on our basic rules of gun set up, table of distance measures and all the various rules we need to know as exhibitors and assistants. We also remind ourselves that the ATF, FMCSA, PHMSA and OSHA are always keeping a close eye on us making sure that we stay compliant with all their respective regulations. In working with fireworks, explosives or any other hazardous material, we are taking on the responsibility of limiting their inherent risks to health, safety and property. We can only do this properly through education.
We want our spectators to see the best we have to offer. That’s why they come to our shows, for great fireworks entertainment. Our shooter training program gives us a chance to socialize and trade stories and ideas with each other about how to create better shows. At the same time, we learn a great deal about the safety and security surrounding the fireworks business from simply talking to each other and discussing the things we learn.
We are looking forward to seeing you all again this year!

Shooting fireworks with a computer ?
This is the reason why multiple e-match's should only be wired in series and not parallel.
The firing modules that you connect the e-match to in all computer systems share the same source of power when it comes time to ignite the e-match, an electrolytic capacitor. When the main control unit is turned on it starts to charge the capacitor that is inside each module. It is similar to a photo flash for a camera. When you turn on the flash unit you can hear an oscillator giving off a high frequency sound as it charges the capacitor. When the flash goes off you can hear that high frequency noise again as the capacitor charges back to capacity again. If the subject for the photo is close the flash goes off but charges quickly and is ready again very soon. If the subject is far away the flash needs more power from the capacitor so it takes longer to recycle before it is ready again.
The power usage of a module is very similar to that of a photo flash.
When the energy to ignite one e-match is needed it can recharge the capacitor almost immediately. When you have multiple e-match's on one circuit, more power must be drawn from the capacitor to fire all of them so it takes more time to recycle the capacitor back to it's full charge.
So What Is All Of This Leading Up To ?
Without going through all the math, the capacitor in a FireOne Module stores about 18 Watts of energy. The capacitor in a PyroSeeking module stores 44 Watts of energy.
Now lets look at an example of 5 e-match's wired in series and then parallel.
According to Ohm's Law:
Resistance in a series circuit = Rt = R1 + R2 + R3......
Resistance in a parallel circuit = Rt = 1/R1 + 1/R2 + .......
There are many manufacturers of e-match these days but I like to use to original daveyfire e-match to base my equations on. I always calculate the e-match resistance at 2ohms and to be safe I always say you should use 2 volts to ignite it. These values are not absolute but they always gave me good results.
So if we wire 5 e-match in series our total resistance will be.
5 times 2 ohm for a total of 10 ohms.
If we wire 5 e-match in parallel then our total resistance is 5 times 0.5 ohms for a total of 2.5 ohms
The voltage I said for each is 2 volts so we need 5 times 2 volts for a total of 10 volts.
The energy needed to fire the 5 e-match is calculated by the following equation.
P = V squared
The Series Circuit = 100 volts = 10 Watts
The Parallel Circuit = 100 volts = 40 Watts
Ohm's Law and Mathematics DO NOT LIE it takes 4 times as much energy to fire 5 e-match that are wired in parallel than it does if they are wired in series.
This may help explain why those 2 shots of 5 e-match that were wired in parallel and cued to fire at the same time off the same module did not work.

I am frequently asked about the science of fireworks by students who wish to make fireworks the subject for their school projects. It is a fascinating subject and excellent for studying chemistry. The most common question I have always been asked is, “what chemicals make the colors in fireworks.” The answer is the color of fireworks is actually produced by burning elements.
If you have ever taken a chemistry class, you might have performed a flame test. The flame test is used to visually determine the identity of an unknown metal or metal ion based on the characteristic color the salt turns the flame of a bunsen burner. The heat of the flame excites the electrons of the metals ions, causing them to emit visible light. Every element has a signature emission spectrum that can be used to differentiate between one element and another.
In making fireworks, we use this characteristic nature of chemicals to produce our colors. Strontium compounds produce red, sodium and iron produce yellow, magnesium and aluminum produce bright white, barium salts produce green and copper compounds produce blue.
These color producing compounds are mixed with oxidizers, fuels, binders and color enhancers to produce the burning “Stars,” that you see in fireworks.
The most common fuels we use are charcoal, aluminum and red gum. Oxidizers, like potassium nitrate and potassium perchlorate, provide the oxygen needed to burn the fuel and binders, like dextrin, hold the mixture together.
These chemical mixtures are well – blended in order to make a consistent, homogeneous mix. They are then wet and either rolled into little balls or pressed into cylindrical shapes and dried. In order to insure that they ignite well, they are coated with a black powder prime and then they are ready to be packed into a firework shell, mine or many other types of effects.
"Arthur Rozzi Pyrotechnics has consistently thrilled audiences at our annual summer Fireworks & Fountain Shows.
The choreography synchronized to music and fountains is amazing, and the set-up and take-down run like clockwork.
It’s a great collaboration.” Colvin Randall, Longwood Gardens, Kennett Square, PA
