Senko Hanabi - A Tradition From Japan

Senko hanabi ( 線香花火 senkō hanabi ) (sparkler - literally: incense-stick fireworks) is a traditional Japanese firework. Essays about them date back to at least 1927.

They are a thin shaft of twisted paper about 20 centimeters long with one end containing a few grains of a black gunpowder. The black powder composition consists of three basic chemicals: potassium nitrate, sulfur, and charcoal .

The pointed end is lit and held straight down, so that the flame is at the bottom. After a few seconds a glowing, molten slag will forml. The molten ball will ignite the second phase of the senko hanabi, silently spraying an array of delicate branching sparks with a range of up to 20 cm] They are ignited away from the wind and held with a steady hand, so that the delicate molten head does not drop and that the two phases of ignition are completed. Senko hanabi are included in packets of fireworks and are ignited last amongst other fireworks.

Senko hanabi are said to somehow hypnotize the viewer into silence and to evoke mono no aware(translated as "an empathy toward things," or "a sensitivity to ephemera"), a Japanese term describing a flash of sadness felt when reminded of the beauty and briefness of life. The poignantly ephemeral has long been appreciated in Japan and is still felt in the quiet celebration of senko hanabi.

Adults and children alike light up senko hanabi. With our superstition, the longer you can keep it burning, is like your life line. Unlike western fireworks, this one is very quiet and gives us a sense of peace and reflection on our lives.
