Metallurgy is the understanding of the properties of metals, so you could try representing it as a lab that lets me use metals more efficiently.
I'd like to build a military academy and start training some soldiers. Just a small number for now, about 1% of the population. For defense.
Legislation passed:
Every town hall is required to have a small bronze cannon in front of it. Every morning at 7 AM a blank shot is fired during the flag raising ceremony. People who can't afford alarm clocks wake up by the sound of the cannon. The cannons represent our nation and our culture, and have become a beloved symbol in every town.
Glassblowing is a nationalized industry.
Citizens must attend school between the ages of 5 and 15. Students can get early dismissal from school days to attend work. Usually mining, growing plants, and blowing glass.
Actions:
Begin mining gold, tin and copper. Mine small quantities of aluminum for experimental purposes. Mine small quantities of uranium for the production of
uranium glass.
Offers:
I'll trade hydroponics for another farming tech.
I'll trade metallurgy for a military or industrial tech.
I'll trade mining for some other basic tech.
And I'll export fine glasswares to anyone who wants them.
