I made a short history of Chemistry to try and remove a bit of handwave.

I actually really like this.

It's a guide without being a guide, with nice enough lore.

Still, I'll miss my crazy handwaves for why it's 2 oxygens to a hydrogen for water.

Nanako did a massive in-depth guide on Chemistry.

I guess we'll just say this is done, really. Too little too late, though.
