A block is a sub-type of building material. Stone and wood can be shaped into blocks at the Mason's workshop or Carpenter's workshop. Glass can be formed as blocks at a Glass Furnace, and metal blocks can be made at the forge from a single metal bar.

Blocks are required to make wells, pumps, and are used when constructing an ashery. They can also be used in place of raw stone or wood in roads and other major constructions (but not in items like crafts or furniture), but the difference is purely in the value. A pillar made out of normal stones is called a rough pillar.

Blocks, unlike raw stone or wood, can stack in bins in bar/block stockpiles.

Blocks have a base value of 5, compared to the raw material value of 3 for stone, wood or glass; metal bars already have a base value of 5. Blocks do not have quality levels.

Blocks are sometimes used as materials during strange moods.

It is possible to turn blocks back into stone. You'll need blocks in a bin (preferably metal) that is exposed to lava. Each blocks object will become a molten object of the same stone type, and because it is in the bin, won't be subsumed into the lava. After it cools down, each object will have reverted to the base stone type. Metal bins are not subject to destruction by the lava. Note that this does result in having stone in bins, a state of affairs that isn't normally possible.
