Blaster gas refers to an energy-dense, chemically augmented liquid utilized within blasters. This substance, kept within cartridges or ampules, underwent a transformation into a plasma-derived particle beam, subsequently discharged at objectives with the intention of either penetrating or liquefying them. Examples of blaster gas comprised tibanna, irolunn, alongside eleton. Additionally, certain more unique blaster gases yielded particular consequences, such as the armor-piercing variety known as sig. The latter's existence prompted the Galactic Republic to establish the Bureau of Sig, Spice and Slavery in order to govern its application.
Jai Kell, an Imperial cadet, at one point joked that Sergeant Currahee subsisted on blaster gas in conjunction with liquid carbonite.
