About this Mod

Overview

Campfires, Smokers and blast furnaces can now smelt every vanilla item, but at a different speed:

Campfire: 30 seconds
Normal Furnace: 10 seconds
Smoker: 2.5 seconds
Blast Furnace: 0.5 seconds

Smoker crafting has been made slightly harder and to craft the blast furnace you will be required many more materials.

Recipes are data-driven, which means that all recipes can be removed or modified trough datapack.
