From what I can tell, this is allowed, But, if i'm wrong, slap me wrists, delete/lock topic or do whatever your going to do.

I've been trying to create any elements I see what I believe could be useful and uploading them to my own TPT fork on GitHub. This is also doubling as an attempt by me to get a decent grasp on C programming while I'm here. ^^

Changes:
Removed OIL<->GAS Relationship
-OIL now compresses into Plastic[PLAS]
-PLAS melts into OIL
-PLAS acts like GOO when under pressure however it does not vanish
-GAS now liquefies into Diesel[DESL] under pressure.
-DESL becomes GAS under negative pressure
-DESL ignites under high pressure and burns slowly
-NEUT turns DESL into GAS
-NEUT turns PLAS into OIL
-Doesn't Break any simulations I've tried so far, but they will need some edits to run as they should

Added COAL
-WOOD becomes COAL under pressure
-COAL burns a lot slower than all other elements as far as I know.
-NEUT turns COAL into WOOD (Known bug: Neutrons bounce off coal)

Added Liquid Oxygen and Oxygen (May later remove Oxygen)

Planned Changes:
-Tungsten/Lamp -> Metal gets very hot without melting and releases photons (Could take a LOOONG time)

I won't be releasing any binaries, not until I figure out SSE and Cross-Compiling at least. If anyone on the forums wants to post some they are welcome too and I will link to them in the initial post. I'll link the 2 wiki articles on building and compiling, I assumed everyone read the wiki ^^'

That's technically charcoal and it'd burn before you'd see the transition. I'll play around with making WOOD turn into COAL at high temperatures.
