There are three tiers of goods manufacturing. Basic, Crafted and Magical.
Basic - Steel, Marble, Planks
Crafted - Crystal, Scrolls, Silk
Magical - Elixir, Gems, Magic Dust
The three relic provinces surrounding your village is what makes up your boosted goods. This means that those manufactories produce a lot more goods than non-boosted. If you collect more of the same relic type as your boosted manufactory, your boost increases and you produce more goods in that manufactory.
Tip: to see what your current boost is, click on your Main Hall and then click the relics tab. If no boost is available, unlock the boost technology in your research
