yes it  is name "Cf"

(sorry i have no pasetbin account so i have to paste the code here.)

old idea. emits neutrons undernormal temperature or hot, produce photons under pressure, colour dependent on pressure, and electrons with negative pressure.

When over 2000 degree c it will turn into a special ISOZ Which explodes into a mixture of photons, protons and neutrons. shines with texture like minecraft lava.
