Block of Quartz

Blocks of Quartz (also known as Quartz Blocks) are mineral blocks crafted from Nether Quartz that are used only for decoration. In the Pocket Edition, their ingredients appear next to powered nether reactors.

Unlike other mineral blocks such as the Block of Iron or Glowstone, they cannot be crafted or broken back into Nether Quartz items. Much like Sandstone, they can only be further crafted into more decorative forms.

Pocket Edition
Normal smooth quartz: Decorative block, used to create other kinds of Quartz blocks.

Chiseled and pillar: Decorative block

Crafting
To craft quartz blocks in Pocket Edition, you need to use a Stonecutter rather than a Crafting Table.

Trivia

 * The block of Quartz is usually considered to be very similar to marble, and sometimes called marble incorrectly.
 * The texture for the pillar quartz block is very similar to a log, and follows the same placement behavior as logs.
 * Quartz was first available in Pocket Edition, before PC. (unless snapshots are counted)
 * Because of the low blast resistance of regular quartz blocks, it may be preferable to use two quartz slabs when making fortifications using quartz.
