Some of the craftable items in Glean can also be mined, but most items can be obtained only by crafting. The recipes for those, as well as some basic crafting-only items such as metal bars, unlock once you have found enough resources to create one of the item. More advanced recipes unlock with the discovery of artifacts. Below are summaries and recipes for all the craftable items:
