So. the Dwarves invented "iron" -- not "discovered" it as an ore, but "invented" it; presumably, a Heroquest (or more than one) was involved. Any details (and in which book(s)) as to the process for creating iron in Glorantha?
Also: in at least some supplements, I understand, Dwarves have guns of some description. Is that muzzle-load, breach-load, or...? Personal weapons (rifles, pistols) or only canon/artillery pieces, or both? Etc...
What other "mytho-tech" do Dwarves possess that others don't (or at least, that Dwarves created, even if the "secret" has spread)?
