A radioactive solid which decays into photons over time. The process can be sped up with negative pressure. It has essentially the opposite reaction of plutonium. ISZS can also be melted into its liquid form at 27C/300.15k (see isotope-z), this normally happens during the duration of the photon decay or it can be done manually with heat.
