Iron ore

Iron ore is created by starting a hematite crushing project on a stone table or work bench. You will be able to crush 525 grams of ore a day, and it will require the use of 750 grams of hematite. Either a hammer (stone, bronze or regular hammer) or sledgehammer must be in your inventory at the time of working on the project, and either one works just as well as the other. However, there are separate projects for each tool, so one may not help on a hematite crushing project designed for hammers, while using a sledgehammer.
