Not fine metal, precision metal. Those ornaments didn’t have to fit something perfectly and if one person’s was slightly bigger than another’s, it didn’t really matter other than maybe for their pride.
I’m talking about making 50 barrels with the exact same measurements (within some small error range) so that they will all fit the same receiver perfectly and can handle a standard sized bullet.
Or, in the case of motors and machines, bearings that spin smoothly, gears that fit together without slipping, the ability to align things well enough that spinning wheels on an axle won’t add a force that wants to rip the axle apart.
Not that electric motors are completely useless without that precision, but there’s only so far you can take them with more maintenance required without that precision.
i’m pretty sure the vikings has fine metal ornaments. and they were centuries earlier than the renaissance.
