5 Most Efficient Fuels for Smelting in Minecraft

Minecraft: Smelting is a way to gain refined goods from raw materials by heating them in a furnace, blast furnace, or smoker.
Players keep in mind many things before smelting items, to save resources and time. There are multiple fuels that can be used to smelt items.
5 Most Efficient Fuels for Smelting:
Lava Bucket:
A lava bucket can be used as an efficient fuel. It has the longest burning value of 1000 seconds, compared to 800 seconds for a coal block (a lava bucket smelts 100 items, and a coal block smelts 80).

After smelting starts, the lava bucket turns into an empty bucket. If players planning on smelting a huge number of items, using the lava bucket is the easiest, as they are renewable via dripstones.
Blocks of coal:
Coal blocks can be crafted only from regular coal, not charcoal. It is crafted in the same way as other mineral blocks. It is a slightly less effective version of the lava, with only 80% of the effect.

However, coal blocks can be stacked to 64, unlike a bucket, which consumes much less space. If players are building something big that needs a lot of smelting, such as structures make entirely from glass, carrying coal is much easier.
Dried Kelp Blocks:
Dried kelp blocks are blocks primarily used as fuel in furnaces, blast furnaces, and smokers. Its burning time is 200 seconds (4000 ticks) , and it is able to smelt 20 items. This is 2.5 times the burn duration of coal and charcoal, and 0.25 times the burn duration of a block of coal.
Blaze Rod:
Blaze rods are items exclusively obtained from blazes. When used in a furnace, a blaze rod lasts 120 seconds (12 items). Overall, while it doesn’t last as long as the above blocks, players can find Blaze Rod fairly easily by creating a blaze farm from a spawner.
Coal:
Coal is a mineral item mainly obtained by harvesting coal ore. It is used as fuel, for crafting torches and campfires, or for trading with villagers. When used in a furnace as fuel, a piece of coal lasts 80 seconds (smelting up to 8 items).
