Flashgold

Flashgold is a magnetized Gold-198 lattice with antimatter inside. It is used to make (virgin) Balefire without needing Balefire to begin with. It is extremely radioactive at 250 RAD/s.

Production
Shapeless recipe of a Gold-198 billet, an Antimatter cell, and some Ionized Particles from a Fusion Reactor.

Use
Flashgold RBMK Fuel Rods to produce Thermonuclear ashes from the spent fuel, which is then used to make Balefire. This will yield on average 44 thermonuclear ashes or 11 Balefire shards.

Trivia

 * It is not pyrophoric, despite regular Au198 being so.
