Minecraft (Pocket Edition)
Quartz Stairs are, for the moment, a Creative Mode only item. There appears to be a glitch in the Stonecutter which prevents the creation of them with a Block of Quartz
Usage / Purpose
Quartz stairs are a decorative form of the typical stair unit. They are especially useful when constructing a building that has a "classical" appearance.
Quartz Stairs are presumed to be stored in stacks of up to 64 units, once craftable in Survival Mode.
The lack of Quartz Stairs has been noted in the Mojang Bug Tracker, but has not been resolved as of release 0.10.0.
