Strontium

Strontium was a red-colored solid substance. It was poisonous, being potentially lethal to inhale. Strontium could be used as fuel for vehicles or explosives, with the use of the substance in the latter leading to red-hued explosions.
In 5 BBY,The mention of strontium in Sabine Wren's in-universe journal represented by Sabine My Rebel Sketchbook is set between the formation of the Spectres and the events of Star Wars Rebels: Spark of Rebellion, both of which Star Wars: Timelines dates to 5 BBY. Sabine Wren, a member of the anti–Galactic Empire rebel crew of the starship Ghost, noted in herStar Wars: Timelines journal strontium as a possible fuel for creating red explosions. After the Galactic Civil War battle on the planet Jakku ten years later, the planet's surface became littered with the wreckage of starships and vehicles, leading to dangerous fuels such as strontium leaking in its sand. At some point prior to her departure from Jakku in 34 ABY, the human scavenger Rey mentioned strontium in the survival guide she was writing. She included in it a note with a visual depiction of a sample of the substance and wrote that strontium colored sand red, a fact that could inform scavengers to proceed with caution.
