Fire Charge

The Fire Charge is an item which can be used as fireball ammunition for Dispensers, or as an inefficient substitute for Flint and Steel.

Crafting
The ingredients can be placed in any crafting slots.

Since Gunpowder and Blaze Powder are obtained from mobs and Charcoal from trees, Fire Charges are a renewable resource.

Use
When used by a player, it instantly places Fire at the clicked location, like a Flint and Steel; however, it has only one use and so is not practical for that purpose.

When a Fire Charge is dispensed from a Dispenser, it acts like a Blaze fireball, flying in a straight line (though with the usual random aim of a Dispenser). When it hits a block, it will place Fire at that location. These fireballs have no explosive effect.

Fire charge can also be used to light a Nether Portal.

History
The Fire Charge was added in snapshot 12w04a.

In snapshot 12w04a it couldn't be crafted with charcoal, only with "regular" coal. This was fixed in the next snapshot.

Bugs

 * When you right click with the Fire Charge on a block, the fire created may not render properly according to the block, making it seem to be floating fire.
 * If it travels out of the render distance it eventually stops in mid air. If this accumulates it can cause major lag in the surrounding area.

Trivia

 * When officially released into Minecraft, Players might use this to grief servers, but not too often because Blaze Powder can only be found in the Nether.
