Ore Crusher

The Ore Crusher crushes ore blocks, making two dust for each block placed in it.

Making an Ore Crusher: To make an Ore Crusher, you will need the following:
 * Nether Brick Fence x1 ***
 * Iron Bar x2   (not an ingot, a bar)
 * Dispenser x1

Place the Dispenser with the slot facing up at the ceiling.

Place Iron Bars on either side of the Dispenser.

Place the Nether Brick Fence on top of the Dispenser by shift right-clicking with the Nether Brick Fence in hand.

Using the Ore Crusher: Look for a response in the chat box. If you receive - "Sorry. I could not recognize this Recipe. Please place the items in the correct pattern into the Dispenser." -, the material may not be crushable.
 * 1) Open the Dispenser and place ore block(s) inside.
 * 2) Leave the ore blocks inside and right-click the Nether Brick Fence.

If you see sparks and hear a click, then you have crushed the ore blocks successfully.

3. When successful, reopen the Dispenser to take your newly-crushed ore dust.

*** Note: This machine seems to require Nether Brick Fence specifically. Other fence types may not work.
