Oxygenation

Setting that can be turned on and off, follows the 4x4 grid, follows air pressure. Max and min values: 1 and -1.
Things will not burn if the value is less than 0.1. Fire will be forced to turn into smoke if the value is less than 0.6. Not burning will be ignored if there is OXYG in the grid. Oxygenation will gradually fill the screen like ambient heat does, and is blocked by any solid/powder/liquid. Oxygenation will decrease when something burns in the grid or the air velocity pushes the oxygen into more oxygen, leaving a vaccum. Oxygenation will also increase when there is OXYG in the grid. PUMP sets the oxygenation value to 1, unless its temperature is negative.
Also if the oxygenation value is 0.5 or higher a grid with a pressure of 150 or higher will become slightly white, more with a higher oxygenation value.

I made this idea when i was gonna go to bed btw

Also another idea: SFUL
Color: 0xFF746736
Made by combining COAL and FWRK. Burns for the same amount of time as COAL but will not break. Makes some pressure when burned (1?), burns as hot as TNT. Will still burn even if the oxygenation value is less than 0.1. Becomes NITR and FIRW when EXOT is run across, and warped by NEUT. Emits some embers (think IGNC or TNT) when burned. Reflects PHOT as 0xFFFCEACB, just because. Only starts burning when struck by lightning, sparked, or at 700 degrees celcius.

Description:
Solid rocket fuel. Makes pressure when burned and always burns.

Extra thing because U42 said to add pyrolysis: Any flammable material can now be converted into something else by heating it up to certain temperatures. If it is WOOD, PLNT, or SPNG, it releases ASH, (explained later) PVPR (also explained later) and FIRE. ASH is a light powder that doesn't burn well (like 1 flammability) and burns at about 50-100 degrees celcius. It also helps PLNT grow a bit while getting absorbed. It absorbs PHOT and can be used instead of GAS in INSL production.  PVPR is a gas that slowly expands and goes away from wherever gravity is coming from, and when accelerated to high enough speeds (8 or so) turns into GAS. It is also slightly flammable.
If it is INSL, it turns into SLDG (explained later) and releases PVPR if it is touching something at 900 degrees or more and the oxygenation value is 0 or less than 0. SLDG can be cooled back into INSL and allows all energy particles except ELEC. It turns into GAS and CAUS when irradiated. It also conducts heat. SLDG is also a viscous liquid.
If the material is COAL it must have an oxygenation value of 0 or less and requires temperatures of 900 degrees or more. It is converted into COKE (explained later) and releases HYGN, GAS, TAR (explained later) and OIL. COKE is a breakable solid that burns for a bit longer than COAL and burns at temperatures of around 500-1500 degrees and can also be used instead of COAL in METL production. COKE can also be used in SFUL production which makes it have a tmp of 1, which causes it to burn at higher temperatures. TAR is an absurdly viscous liquid that is highly flammable and will ignite at 13 degrees no matter what. Any other flammable element will ignite at whatever other temperature they would without oxygenation.
COKE breaks into BCOK when at a pressure of 3 after 40 frames, like COAL. COKE turns into CO2 when exposed to OXYG and irradiated with NEUT, same with BCOK.
BCOK has the same properties as COKE except it's a powder.

Element colors:

Uses the same system as deco
ASH: 0xFF130E0E
PVPR: 0xFFF7C400
SLDG: 0xFF442D18
COKE: 0xFF3A3A3A
BCOK: 0xFF4F4F4F
TAR: 0xFF1A1109

Edit: I forgot to add element descriptions so here:
ASH: Ash. Formed from pyrolysis, acts as fertilizer.
PVPR: Pyrolytic vapor, can be refined into GAS by launching it at high speeds.
SLDG: Molten plastic. Very bad for you.
COKE: Refined coal, burns slowly and hot enough to melt iron.
BCOK: Broken coke. Burns slowly, heavy particles.
TAR: Coal tar, made from refining coal into coke.
