The Free Kingdoms?
Also, a lot more goes into the production of fiber optic wires than just melting sand down in the right way.
I'm not sure what you mean by "cars will probably be made for ceramics or titanium. Dirt and sand are about the cheapest things imaginable". Titanium is not "dirt" or "sand", it's an incredibly rare, very expensive metal.
Gold was still valuable in AoL. Not as valuable as rare-earth metals like Cadium, but that's how it is in real life.
Gold is way, way, way rarer than copper. Also, gold melts a lot easier. Cars wouldn't be made of ceramics for the same reason they aren't today: ceramics are too brittle and don't have a high impact tolerance.
Limelights aren't made from quicklime and water; you have to heat the quicklime up quite a bit for it to work. It's exceedingly inefficient compared to electric lights, which is why we don't use limelights anymore.
I guess my point is is that not a lot of things will necessarily be different from ours except when Allomancy has a noticeable effect on the culture... Such as streetcars. I believe that streetcars can easily be pushed/pulled by mistings, which makes them more efficient than cars. We've already seen the introduction of cars in the broadsheets of AoL.
