Smelting Recipe


Blast furnaces are similar to furnaces but are used to smelt mineral blocks in particular. When a smelting item and a fuel is placed into the blast furnace, the block state will change to lit and the item will smelt, twice as fast as a regular furnace. Fuel is also used at double the rate of regular furnaces, so that the amount of items cooked per fuel stays the same. The product can then be collected by pressing use on the blast furnace. Like normal furnaces, a hopper can be fed into a blast furnace and can also pick up items from it.

Light source[edit]

Blast furnaces emit a light level of 13 when active, similar to normal furnaces.

Custom name[edit]

By default, the GUI of a furnace is labeled "Blast Furnace", but this name can be customized by naming it in an anvil before placing it, or by changing the CustomName tag using the /data command.

Change profession[edit]

If a village has a blast furnace and there's no armorer villager, any nearby villager who hasn't chosen a work station has a chance to change their profession to armorer.

    •  CustomName: Optional. The name of this container in JSON text component, which will display in its GUI where the default name ordinarily is.

    •  CookTimeTotal: Number of ticks It takes for the item to be smelted.
    •  RecipeLocationN: N is the number of the recipe, starting at 0. The recipe name that has been used, used to calculate experience given to the player when taking out the resulting item.
    •  RecipeAmountN: N is the number of the recipe, starting at 0. How many times recipe N has been used, used to calculate experience given to the player when taking out the resulting item.
    •  RecipeUsedSize: How many recipes have been used, creates corresponding RecipeLocationN and RecipeAmountN tags, used to calculate experience given to the player when taking out the resulting item.
