With the 1400 technology cutoff are there plans for platinum, aluminium, bismuth, and nickel silver what with them being on the other side of it?
How Toady sees it is that there are some aspects of Dwarven society which is more advanced then the 1400 cut off. For example Dwarves have certain cuts more advanced then the 1400s.
Though I will admit my Chemist friend says that natural aluminium is actually outright nonexistant.
I would like to see Toady chime in on this regardless. I've poked around wikipedia and compiled the information surrounding the issues here for the convenience of forumgoers.
Platinum
does exist in
vary rare native desposits naturally. Platinum is simply a rare element, and while it was not identified before 1400, there were no actual physical technical limitations to just picking it up, should you be astonishingly lucky enough to find some. I would agree that it is substantially more abundant in Dwarf Fortress than it ought to be (especially when you chance upon a castle made entirely of native platinum).
Have to agree about the aluminum. Unless you can do at least
some chemistry, there is simply no aluminum to be smelted anywhere. Even today, aluminum production is prohibitively costly in terms of electricity, and frankly it is somewhat surprising how common it is, given how inconvenient it is to produce.
Bismuth has been around since ancient times, but was not identified as a unique metal until the 16th century (may have been mistaken for tin or zinc). In my own mind I'm fine with the metal being in the game as-is, since it
was in use since antiquity, and I don't know how Toady would simulate mistaking one metal for another (though once some kind of fantastical generated metals get into the game, perhaps something sensible would become available).
Nickel-Silver, while not produced until the 19th century, again nothing about its composition would make its production at an earlier time impossible, however it would possibly be more appropriate to use cupronickel in stead, since cupronickel looks the same and
was available since antiquity. As an added bonus, cupronickel is corrosion-resistant in seawater, so if that's ever a thing that gets into the game, it would be a good idea for this alloy to be available.
