Ore Gravel

Ore Gravel is a block added by Ex Nihilo. There are 10 types of Ore Gravel: Aluminum, Copper, Gold, Iron, Lead, Nickel, Osmium, Platinum, Silver, and Tin. Some types of Ore Gravel have Ender and Nether variations.

The Ex Astris mod also adds Ardite, Cobalt, and Draconium versions of Ore Gravel.

Obtaining
Ore Gravel can be crafted from Broken Ore.

Usage
The primary purpose of Ore Gravel is to serve as an intermediary step where work with a Hammer results in greater eventual metal production.
 * Ore Gravel is hammered into Crushed Ore, with a chance to drop more than four per block.
 * Crushed Ore is crafted into Ore Sand.
 * Ore Sand is hammered into Powdered Ore, again with a chance to drop more than four per block.
 * Powdered Ore is crafted into Ore Dust for final smelting (and a Pulverizer or Tinkers' Construct Smeltery can double the ingots produced from smelting Ore Sand).

Ore Gravels are gravity blocks — if placed in the world without a supporting block, they fall like Gravel.

Hammer
Ore Gravel (Such as Tin Gravel and Iron Gravel) can be mined with a Hammer to produce Crushed Ore. Each Ore Gravel always drops four Crushed Ore, has a 50% chance to drop a fifth Crushed Ore (60% with luck bonus), a 5% chance to drop a sixth Crushed Ore (15% with luck bonus), and a 0% chance to drop a seventh Crushed Ore (5% with luck bonus).

Furnace
Ore Gravel can be smelted into ingots.

Redstone Furnace
Ore Gravel can be smelted into ingots.

Thermal Foundation
Some Ore Gravel can be processed into metal dusts in a Pulverizer. Where secondary outputs exist, the probability is 10%.

Tinkers' Construct
Ore Gravel can be smelted in a Tinkers' Construct Smeltery to produce 288 mB of Molten Metal of the appropriate type (enough to produce two ingots of metal).

Recipe
Ore Gravel can be crafted into Broken Ore (but the only thing you can do with the Broken Ore is craft it back into Ore Gravel).
