Element #21 (ACID):
  Name: Acid
  Acid corrodes soft materials.
  Special Cases:
    Explosives:
      * C-4
      * NITR
      * GUN
      * RBDM
      * LRBD
    Igniters:
      * FIRE
      * PLSM
      * LAVA
      * SPRK
      * PHOT (when PHOTIgnite = 1)
      * High temperature PROT
    * WTRV (turns into CAUS)
    * GLAS
    * CLNE
    * ACID and CAUS
    * PCLN
    * GOLD
    * QRTZ
    * ISOZ
  When .life = 75, it's "unaffected".

Element #86 (CAUS):
  Name: Caustic Gas
  Acts like ACID. Doesn't trigger explosives.
  Reactions:
    CAUS + GAS + High Pressure = RFRG/RFGL

Element #107 (ISOZ):
  Name: Isotope-Z
  Radioactive liquid, decays into photons when touching PHOT or under negative pressure.
  Solidified into ISZS) at < -113.15 C

Element #108 (ISZS):
  Name: Isotope-Z (solid)
  A radioactive solid which decays into photons over time.
  Melted into ISOZ at > 26.85 C

Element #183 (RFRG):
  Name: Refrigerant
  Heats up and liquefies under pressure (> 2 Pressure).

Element #184 (RFGL):
  Name: Liquid Refrigerant
  Cools down and evaporates under negative pressure (< 2 Pressure).
  
Element #187 (E187):
  Acts like ISOZ.
  E187 + ACID + (NEUT) = "Infected" E187
