Block of Quartz

Blocks of Quartz are mineral blocks crafted from Nether Quartz that are used only for decoration. In the Pocket Edition, they are one of the blocks that appear when a Nether Reactor is activated.

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.

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 wooden log, and follows the same placement behavior as logs.
 * Quartz was first available in Pocket Edition, before PC.
