Projectisium

Projectisium, known colloquially as 'slug juice' or 'gun slime', was a synthetic, volatile slime used as a propellant in most commercial slugthrower models. Refined projectisium was a transparent pink in color, while unrefined projectisium was red. While many different substances were used in ancient slugthrowers, the widely accepted predecessor to projectisium was an oil that was secreted from a fungus native to Onderon, which was used in the slug rifles of both Republic and Onderonian soldiers until projectisium was discovered by Alderaanian scientists during the early Old Sith Wars era, briefly replacing older models with more advanced slug rifles until phasers (early blasters) were introduced on a wide scale circa 3998 BBY. Some artillery cannons used by the Tion Hegemony and Corporate Sector Authority used projectisium to propel explosive shells.
