to get napalm
with lua

tpt.el.gel.flammable=1

There's a mod that add napalm called cracker1000's mod (Best mod because add base which is opposite of acid). Also this mod adds sodium and chlorine which react together in a process called combustion, and create sodium chloride (Salt) that already exists in the game, but has no way to be created and this mod adds it so. Also, base and acid react together to form sodium chloride (Salt) another way to create salt. So, this mod recommended.

what about adding a bomb which lights up the whole screen and turns it all to ash?

magnesium, bomb, but exploded by heat, not auto explode, because magnesium acts a lot like BOMB when it burns, with sparks, and a little pop/explosion

also maybe COLF/ cooling fluid, which would slowly cool down elements it touches when they go above the COLF's temperature, which could help people make more ambient heat friendly stuff, and would be cool (pun intended) for weapon cooling and thermal weapon resistant armor
