Again, I'm talking about the lovely Japanese Fireworks (花火) ! In my personal opinion, the Japanse shells are not only the most beautiful, but are also the big ones in general and there's a variety of sizes. Years ago, I found a chart on http://japan-fireworks.com/ website with the most common sizes , but for the most of the readers of this blog, that probably don't understand Japanese, may be difficult to understand some data in the chart, so I did a translation for you and here it is (in the left ou can see the translated information): Image credits to http://japan-fireworks.com/ As you can see in the image, the most common sizes vary from 90mm to 900mm. A very interesting and useful info in this chart is the lift charge weight.
Some words about the Black Powder and Fireworks art, science and technique around the World.
