The Jumbo Furnace Supports Jumbo Recipes
This is an example of how a JSON recipe that takes multiple ingredients can be defined. The Jumbo Furnace supports these recipes, but this mod does not add any by itself. Note that cooking times for Jumbo Furnace recipes cannot be specified per-recipe.
The Jumbo Furnace's Item Handling Interfaces
Every face of the Jumbo Furnace is connected to one of its three inventories; the top faces access its inputs, the side faces access its fuel, and the bottom faces access its outputs.
The Jumbo Furnace's GUI
The Jumbo Furnace can use standard smelting recipes in addition to its special recipes.
The Jumbo Furnace
Automatically formed when a solid cube of furnaces is placed by a player. The furnaces don't have to face a particular direction.
Tag Stack Ingredient
The "jumbofurnace:tag_stack" ingredient type takes an item tag ID and a stack size count. This ingredient type allows recipes to use items-from-a-given-tag with stack sizes greater than 1.
