ALUM: Aluminium/Aluminum. A solid which breaks into BREL when heated under pressure. Conducts faster than METL, but slower than GOLD. When heated under normal conditions, melts like a normal metal. Under low pressure, turns WATR to ACID. Makes SAND when burnt, and FIRE when CAUT reacts with it.

FERC: Ferrocerium. A solid, that when hit by particles that are moving quickly, some of it breaks and becomes very hot EMBR. Burns brightly and easily, producing a small amount of PHOT. Created by mixing BREL and BRMT at lower temperatures.

WSTW: Waste Water. A liquid that is created when MERC, PLUT, or URAN come into contact with any type of water. Turns WATR and its derivatives into WASW in a cascading effect. Doesn't freeze, but does boil, creating MERC. More conductive than SLTW. Turned into DSTW when exposed to SOAP.

DRYW: Dry water. A liquid that is formed when DRIC melts under very high pressure, or when CO2 is cooled under the same pressure. Produces a large amount of pressure when it boils (if the pressure is released).

I don't really expect these to be added, but I feel like they would make a nice addition to the game.
