Ash
Ash was the solid, somewhat powdery substance that was left over after any fuel would undergo combustion.
In 2269, when told to commence his sensor sweep by James T. Kirk and before being cut off by a loud noise, Arex said, "Sensors show crystalline surface heavily fractured by lava flows. Ash and smoke suspended in oxygen-nitrogen atmosphere." (TAS: "The Terratin Incident")
