About this project
What does Alloy Smelter add?
Alloy Smelter
This mod adds 3 levels of multi-block structure for smelting ore, made of Bricks, made of Polished Blackstone, made of End Stone Bricks. All recipes from lower level forges work in higher level forges. In its basic configuration, it serves as a simple way to increase the speed of smelting ores, but you can add recipes and change block for forge as you see fit. These features are primarily intended for mod and modpack authors.

IMPORTANT
If you have an old version of the mod and you updated to the new version, where there are 5 slots in the forge, if you placed forge block in your world, the world will not start. Break all the forge blocks in your world, then update the mod.
There are only two smelting recipes for each vanilla ore for each forge level. When smelting one item, it can be placed in any slot in the forge. If a recipe contains 2+ items, the order in which they are placed in the slots is important.
Features
Forge automation
You can use both hoppers and blocks from other mods (ae2, etc.) to automate the forge. For the pattern provider (ae2): on any side except the top and bottom. For hoppers: the output slot is located bottom the forge, and the input slot is on top. The hopper loads items into the input slots like a chest; the hopper does not have access to the fuel slot.
Change blocks for each level of the forge.
To change the blocks required for the forge, you need to add the required tag to the block. You can do this using datapack or kubejs.
Each forge level has its own BlockTag:
- Forge Tier 1:
alloy_smelter:alloy_smelter_blocks_tier1 - Forge Tier 2:
alloy_smelter:alloy_smelter_blocks_tier2 - Forge Tier 3:
alloy_smelter:alloy_smelter_blocks_tier3
Add custom fuel
If you want to add fuel for the smelter, just add this tag "alloy_smelter:alloy_smelter_fuel" to any other fuel.
Add and edit recipes for the forge
To create a recipe you can use datapacks or kubejs. Having created a json file with your recipe.
