Smelting is a method of obtaining refined goods from raw materials by heating in a furnace, blast furnace, or smoker. For example, raw iron can be smelted to produce iron ingots using coal as fuel. Like crafting, smelting uses recipes to determine what item is produced, but its recipes are simpler. Smelting also yields experience.
The furnace, blast furnace, and smoker share a similar interface: At the upper left is a slot for smeltable item input, below that is a slot for fuel input, and on the right is a slot where output items accumulate and can be removed by the player. Flames above the fuel slot act as a gauge showing the gradual consumption of the current fuel item, and an arrow in the middle gradually fills to show the progress of smelting the current input item.
To smelt, an input item and fuel must be placed into the input and fuel slots, respectively. The furnace then begins to smelt and will continue even after the player closes the interface. (The player can still tell when a furnace is working by its block texture showing flames and fire particle effects appearing.)
The furnace burns one fuel item at a time, with the fuel gauge indicating how much of that item's burn time remains. As each fuel item is fully consumed, another one is taken from the fuel slot and the gauge starts over.
Smeltable input items are also processed one at a time, but are not removed from the input slot while smelting is in progress. The arrow indicates how much of the smelting process has completed. When the arrow is full, the input item is removed from the input stack and an output item is added to the output stack. Smelting of the next input item then begins immediately.
If smelting stops while a fuel item is still burning (a normal occurrence), the furnace will continue to run visually but no more input items will be processed. If the fuel is exhausted (and the fuel gauge is empty) when an item is partly smelted, the smelting progress is undone at double speed and the item remains in the input stack.
Smelting is suspended if players move far enough away from the furnace (including going to another dimension) that simulation stops in the chunk the furnace is in. It will resume when a player returns.
If the player sleeps in a bed while a furnace is smelting items, the furnace's progress remains the same as if the bed had not been used and no additional time had passed. This is because when a player sleeps in a bed, no time actually passes; the game simply sets the time of day to morning.
The furnace keeps track of experience for each item as smelting is completed for it, accumulating it in a hidden counter. It remembers the total earned experience even if a hopper is used to remove the items from the output slot. This earned experience is awarded to the next player who uses the interface to remove items manually, after which the counter is reset. (If the player takes some of the output but leaves some in the slot, the experience corresponding to those items is retained by the furnace and not awarded to the player.) However, in Bedrock Edition the saved experience count is not reset due to bug MCPE-71777.
All food recipes can be used in a furnace or smoker. Food can alternatively be cooked on a campfire, which doesn't require any fuel and is faster (when cooking 4 at a time) than a furnace, but which doesn't award any experience and is slower than a smoker.
The following additional ores can be smelted, but it's more efficient to mine them with an appropriate pickaxe. Mining them saves fuel and in most cases yields more product and experience, especially if the pickaxe has a Fortune enchantment. Smelting them, though, allows obtaining them from an automatic device. The ore blocks themselves can be obtained only via the Silk Touch enchantment.
For fractional experience values, first multiply this value by the number of smelted items removed from the furnace, then award the player the whole-number part, and if there is a fractional part remaining, this represents the chance of an additional experience point.
For larger jobs, a single lava bucket or a block of coal can smelt more items than can fit in the furnaceboth input and output are limited to a stack of 64, but a block of coal smelts 80 items, and lava can smelt 100 items.
The smelting process can be automated with hoppers on the top and bottom of the furnace. For larger smelting jobs, a third hopper on the side of the furnace can feed in fuel and, in case of lava being used as fuel, any empty buckets come out of the bottom hopper. This automatically feeds and empties the furnace so that different materials can be smelted in the same batch with no loss.
Whenever a hopper or minecart with hopper removes items from a furnace, any experience earned from cooking or smelting the removed items is saved in the furnace and awarded to the next player who manually removes an item from the furnace's output slot. This saved experience is in addition to that earned for the manually removed item(s).
If the trip you are planning takes you into the outback or far north then getting an idea on the petrol/diesel price per litre is a must as it can be 50 c or even more expensive per litre. Outback fuel is not cheap!
Filling up during or just after a fuel tanker has been and emptied is not the best idea as the refilling action causes the settlement on the bottom to stir up mixing with the new fuel. You can't know when one has just been but if you see one there unloading take caution!
I also recommend using the premium fuels versus cheaper fuels, its better for the engine and will give you more kilometersfor your hard earned $$'s. doing it just once for the first time won't make any difference, it needs to be used for about 5 full tanks before you will notice a real difference.
Formula for litersper 100 km: Litersused * 100 divided by kilometerstravelled = answer per 100 km Example: 107 liters* 100 = 10700 / by 790 km = 13.54l per 100 km Formula for kilometersper liter: Use the kilometerstravelled divided by litersused. Example: 790 kilometerstravelled divided by 107 liters= 7.38km perliter Litersrequired for travel formula: To estimate the litersrequired for a trip: 2000 km trip divided by 100 = 20.00 20.00 * 13.54 (the above litersper 100 km) = 270.80 litersrequired. Keep in mind different terrain will use more fuel; this is based on high way driving fuel consumption.
