PeRoXiDe
formed when HYGN and OXYG come within 2 pixels of eachother at 5 pressure and 200c,
slowly decomposes into HYGN and OXYG, burns with 1300C and 3 pressure, and ignites when it touches PTNM
wouldn't be surprised if this gets rejected, i made this up in like 2 minutes
Confirmed. H2O2 decomposes into water and oxygen.
