"Mass production" refers to making standardized products in a highly mechanical manner, using things like assembly lines, molds, and that sort of thing. It's a trade-off between a gain in speed/ease of production and a loss of individual variations between items, and whatever craftsmanship/quality hand-production would be able to offer instead.
You have obviously never been to an Asian carpentry shop. Know those 12" wooden dragon figurines that everyone seems to have?
Seriously all carved by one dude working 12 hours a day and makes 40 of them, by hand, and they're neigh identical, every last one.
I'd call that mass produced.
I'll see if I can come up with a picture.
Edit:
My point is, "hand carved" only means that the mistakes are unique, not the design.
There's still a point of pride in doing it by hand, and dwarves are pretty big on that.
Also, there's absolutely no indication that dwarves follow the same design pattern repetitiously in order to save time. In anything, it's the opposite: Every item made is distinct from every other item and is rolled completely separately. The only reason the effects of this aren't clear is because items are pretty samey at the moment, in the sense that not much is going to distinguish between those mugs in the first place.
Sounds like a "Manufacture".
That technically applies to making
anything, in any manner involving tools, but I think I know what you mean, and the above applies.
sand and glass trading officially in for next version.
It's been mentioned in this thread at least twice; we know.
