Type: Walls.
Works like a detector when SMKE, FIRE or PLSM touches it. Other elements don't trigger it. Lets all particles and pressure through.
Color: Yellow dots.
Use: Making oil/coal power plants, fire detectors and everything related to burning.

Element: Neutral Matter (NMAT)
Solid. Doesn't annihillates when AMTR touches it. SING can't annihillate NMAT too, but it will turn it into PNMT (powdered neutral matter) or just make it melt.
Breaks at 3-5 pressure.
Can be melted at 2000C.
Made by AMTR + SING (created in powder form, but can be melted and when cooled turns solid)
Use: Making AMTR containers.

Element: Liqiud Hydrogen (LHYD or LH2)
Liquid. Made by cooling H2 to very low temperature.
When flame touches it, explodes with 5000-6000 C plasma. Also explodes when gets heated very fast, from pressure and from touching LOXY or OXYG.
Use: Making explosives.
