Cassiterite is the only ore (in DF) that can be smelted into tin. This ore can also be smelted with others to create bronze, trifle pewter, and fine pewter. In the world of Dwarf Fortress, cassiterite is found in only layers of granite, as veins.

Smelting

Cassiterite is a required ingredient to make several types of metal alloy bars from ore at a smelter:

• Tin bars
• Bronze bars - with copper nuggets, malachite, or tetrahedrite
• Trifle pewter bars - with copper nuggets, malachite or tetrahedrite (takes 2 cassiterite)
• Fine pewter bars - with copper nuggets, malachite or tetrahedrite (takes 3 cassiterite)

The above can also be made from bars of tin combined with bars of the appropriate metals. Note that bismuth bronze and lay pewter, both of which require tin, cannot be made directly from cassiterite, but must first be smelted into tin bars.
