Recent innovations\u2014including the use of (bi)carbonate-based compositions and the integration of metal powders\u2014have significantly improved safety and visual performance. This study introduces a pellet-based design called the Dragon Tear, which standardizes the sparkler&#8217;s core composition for better reproducibility and ease of handling. These pellets can be safely stored, transported, and later wrapped in paper by the end user to create a functional sparkler. With added magnesium or magnalium, the design produces a striking glitter effect in the final phase of combustion. The Dragon Tear bridges traditional beauty with modern practicality, offering a scalable, low-risk alternative that preserves the art of polysulfide sparklers for future generations.<\/p>\n<p>&nbsp;<\/p>\n<hr \/>\n<p>Ref: JPyro 2025 (101-138)<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Frederick Van Der Sypt, M.D. Abstract: Polysulfide sparklers are renowned for their delicate spark display and complex reaction dynamics, rooted in the centuries-old Japanese tradition of Senko Hanabi.
