Copper: CPPR symbol. Great conductor of electricity, reddish colored metal (0xFF871800), the melting point is 1038 ° C or 1311.15K or 1900.4 ° F.
Reinforced Concrete: Symbol RECN. It blocks all pressure, does not conduct electricity and heat, highly resistant but melts at high temperatures, the color is 0xFFA0A0A0 (# a0a0a0 or rgb 89, 71, 71), it is a common solid and not a powder. Cloud: Symbol CLOU or CLUD or CLOD, I do not know. It always goes up, white, it's a gas and after a while, with low temperatures, it turns into WATR.
Storm Cloud: Symbol may be STCL, it is gray and also causes some lightning to emerge and also releases more water than the one mentioned above, the common cloud.
Chlorine: Symbol CL, greenish, toxic and corrosive gas for structures, mix with WATR or DSTW form ACID, mix with SLTW, form ACID and SALT and DSTW.

Fog is considered considered cloud perhaps when sparked it can produce lighting, but will it break saves? Caustic Gas is a corrosive gas which destroys structures except diamond. Copper has been rejected, but doesn't mean it will be added.
This belongs in the feedback section too. A moderator will move it there! So you don't have to remake this thread. Great imagination though.
Caustic gas does not replace chlorine, caustic gas is a base and chlorine forms acids and Fog doesn't replace storm cloud

You pretty much described caustic gas. Only a few minor reactions don't create caustic gas. If fog don't break saves when sparked it could possibly change color. TPT isn't meant to be super realistic and have every reaction and element.
