About this Mod
What this adds
This mod adds 7 new levels of furnaces to the game. Currently the ones implemented are: Copper Furnace, Iron Furnace, Gold Furnace, Amethyst Furnace, Diamond Furnace, Emerald Furnace and Netherite Furnace. Each tier has an increased smelting time allowing for more fuel efficiency and less time wasted, the speeds are obviously based on the material's worth and rarity. Beware that each furnace has the same resistance as the original blocks materials so a netherite furnace might be quite tough to break.
How to get them
To craft each furnace you are gonna need, in most cases, the furnace from the previous material, for example to craft the iron furnace you need 1 copper furnace, 1 iron block and 7 iron ingots. For the copper furnace you have to use the standard furnace. Two of the tiers are optional, that is the amethyst furnace, which can be used for the diamond furnace but the same can be done with the golden one and the copper furnace.
