I have no idea what the numbers or percentages mean, but if we can't store more copper we'll feel wasteful gaining more space.
Research Stone Path: Stockpiles
You try to push the button, but nothing changes.
Forge for food!
Being a dwarf, you are fully capable of using a forge as a kitchen. You've always wanted to try, but never got the chance because forge time is usually too valuable to waste on food. Since you have no more copper, this is the perfect chance. Your fermented berry and bark soup is a popular change of pace, but only because there's nothing better.
The loremaster finishes his research into stockpiles and calendars. Small ore stockpiles will be included in the workshops, and more may be built if you feel the need. With the calendar, you now know that it's halfway through summer. You won't be able to forage in winter.
Despite all your foraging, you're not quite ready to start farming yet. You do get a set of workshops built, and will soon be able to start making tools. You put a button near the forge, for the smiths to appreciate in their down time.
