Polysulfide sparklers revisited: a practical introduction to Carbo Hanabi

Frederick Van Der Sypt, M.D

Abstract: Polysulfide sparklers in the form of Senko Hanabi have been enjoyed for centuries. Research has shown that potassium nitrate can be replaced with non-oxidizing salts providing equally performing compositions that are non-explosive. This article aims to translate this research into practice and presents a detailed construction method for Carbo Hanabi: polysulfide sparklers made with potassium (hydrogen) carbonate. Additionally, it describes the inclusion of magnesium and magnalium in the composition to complement the delicate display of golden sparks with an impressive and bright finale
