What is Hephaestus Forge?
Hephaestus Forge is part of this pack's mod list, and the version you get here is 1.0.16. It has been in the pack since version 1.0.2 or earlier, so it is not a recent addition.[1]
The jar the pack ships is hephaestus-neoforge-26.1.2-1.0.16.jar. If you ever need to check that your install matches the pack, that is the file name to look for.[1]
How do you get started with Hephaestus Forge?
5 parts
Welcome to Hephaestus Forge! In this pack the early game is about molten metal: you pour it into a casting table or a casting basin and get items out. What I can confirm here are the recipes, so this section follows those and doesn't cover how to build the smeltery itself.[2]
Step one: make a Blank Cast
Start with the Blank Cast. The pack adds a casting table recipe that makes it from 90 units of Molten Copper, so copper is the first metal to get into liquid form.[2]
Casting Table (hephaestus)
Recipe id: hephaestus:smeltery/casting/casts/blank_cast
Added by the pack: 90 units of molten copper poured in a casting table.
Step two: make the shaped casts
The other casts use the same casting table and the same amount of molten copper, 90 units each: Ingot Cast, Nugget Cast, Plate Cast, Gear Cast, Rod Cast and Gem Cast. The ingot cast is a handy one to start with.[2]
Casting Table (hephaestus)
Recipe id: hephaestus:smeltery/casting/casts/ingot_cast
Mod recipe: 90 units of molten copper in a casting table.
Step three: cast your first cobalt
A casting table turns 90 units of Molten Cobalt into a Cobalt Ingot. For storage, a casting basin turns 810 units into a Block of Cobalt.[2]
Casting Table (hephaestus)
Recipe id: hephaestus:smeltery/casting/table/metal/cobalt/ingot_cast
Casting table, 90 units of molten cobalt.
Casting Basin (hephaestus)
Recipe id: hephaestus:smeltery/casting/basin/metal/cobalt/block_cast
Casting basin, 810 units of molten cobalt.
Step four: try an alloy
Alloy recipes combine molten metals into new ones. A simple one is Molten Brass, which takes equal parts Molten Copper and Molten Zinc and makes 180 units from 90 of each.[2]
Mod recipe: 90 units each of molten copper and molten zinc make 180 units of molten brass.
Changed by the pack.
Pack-added recipes to know about
- The pack adds an obsidian alloy recipe: 1,000 units of lava and 1,000 units of water make 288 units of Molten Obsidian.[2]
- Seared stone can be cast in a basin from 144 units of Molten Seared Stone, also a pack-added recipe.[2]
- The pack adds a melting recipe that turns 50 units of lava into 90 units of molten steel for the steel plate. Netherite nuggets melt from 50 units of Molten Blaze into 10 units of Molten Netherite.[2]
Casting Basin (hephaestus)
Recipe id: hephaestus:smeltery/casting/basin/misc/seared_stone
Added by the pack: 144 units of molten seared stone in a casting basin.
How does Hephaestus Forge work?
5 parts
The sources for Hephaestus Forge in this pack show its recipes and block names, not the rules for building and running its structures. So this section covers what is confirmed: the recipe types (melting, alloying, table casting and basin casting) and the values this pack sets for them.[2][3]
Blocks the mod adds
The language file lists these functional blocks: Seared Melter, Seared Heater, Seared Fuel Tank, Seared Ingot Tank, Seared Casting Tank, Seared Casting Table, Seared Casting Basin, Seared Drain, Seared Duct, Seared Chute, Seared Channel, Seared Faucet, Seared Fuel Gauge and Seared Ingot Gauge. It also lists many decorative seared blocks, such as seared bricks, pavers, tiles and roads, each with slab, stair and wall variants.[3]
Melting
The pack adds its own melting recipes. The recipe dump counts 916 melting recipes that take a vanilla ingredient and make a Hephaestus fluid, with 69 different results. It also counts 467 that take a Hephaestus ingredient. Each group has just 1 distinct ingredient, and the examples written out use lava or Molten Blaze.[2]
- The steel plate melting recipe turns 50 lava into 90 Molten Steel.[2]
- The gold adze head recipe turns 50 lava into 180 Molten Gold, and the broad axe head recipe turns 50 lava into 720.[2]
- The netherite nugget recipe turns 50 Molten Blaze into 10 Molten Netherite. The netherite adze head recipe gives 180 from 50 Molten Blaze, and the broad axe head recipe gives 720.[2]
Alloying
Alloy recipes combine fluids into a new one. Brass, bronze and constantan below are the mod's own recipes, and the pack adds an obsidian alloy.[2]
- Molten Brass: 90 Molten Copper and 90 Molten Zinc make 180.[2]
- Molten Bronze: 270 Molten Copper and 90 Molten Tin make 360.[2]
- Molten Constantan: 90 Molten Copper and 90 Molten Nickel make 180.[2]
- Molten Obsidian: 1,000 lava and 1,000 water make 288. This is a pack recipe.[2]
Brass is the mod's own alloy recipe.
Alloy (hephaestus)
Recipe id: hephaestus:smeltery/alloying/obsidian
The pack adds this obsidian alloy recipe.
Casting
Casting turns fluid into solid items. There are 10 table casting recipes in the dump. The casts below each cost 90 Molten Copper. The Blank Cast recipe is added by the pack, while Gear Cast and Gem Cast are the mod's own.[2]
Casting Table (hephaestus)
Recipe id: hephaestus:smeltery/casting/casts/blank_cast
Pack-added table casting recipe for the blank cast.
Same fluid cost as the blank cast, from the mod itself.
Basin casting handles block-sized results. 810 Molten Cobalt casts into a Block of Cobalt (mod recipe). The pack adds a recipe that casts 144 Molten Seared Stone into Seared Stone.[2]
Casting Basin (hephaestus)
Recipe id: hephaestus:smeltery/casting/basin/misc/seared_stone
Pack-added basin recipe for seared stone.
Clear glass
The pack removed the mod's own recipe for Clear Glass and added a stonecutting recipe for it. Clear glass is also in the c:chisel/glass block tag alongside Connected Glass blocks.[2][4][5]
The pack's stonecutting route to clear glass.
How do you progress through Hephaestus Forge?
7 parts
Same as in the FTB Evolution 2 1.1.0 guide
Hephaestus Forge in this pack is a recipe-driven path: you work up from seared stone, through copper casts, to alloys and finally to the rare metals. The stages below follow the in-pack recipes, and I flag every place where the pack added or changed something.[6]
Seared stone and forge bricks
The foundation is Seared Stone. The mod's smelting recipes for Seared Stone, Cracked Seared Bricks, Seared Creeper and Seared Paver are all still there. On top of that, the pack adds a casting basin recipe that makes seared stone from Molten Seared Stone.[6]
Casting Basin (hephaestus)
Recipe id: hephaestus:smeltery/casting/basin/misc/seared_stone
Pack-added casting basin recipe for seared stone.
Casting Table (hephaestus)
Recipe id: hephaestus:smeltery/casting/table/misc/forge_brick
The pack also adds this casting table recipe for the forge brick.
Seared blocks also come in decorative shapes. The crafting recipes cover slabs, stairs and walls for seared bricks, seared cobblestone, cracked seared bricks and seared creeper, plus a fancy seared brick slab.[6]
Casts
Next you need casts. The Blank Cast recipe is added by the pack. The Ingot Cast, Nugget Cast, Gem Cast, Gear Cast, Plate Cast and Rod Cast recipes are the mod's own, all made on a casting table.[6]
Casting Table (hephaestus)
Recipe id: hephaestus:smeltery/casting/casts/blank_cast
Pack-added casting table recipe.
Casting Table (hephaestus)
Recipe id: hephaestus:smeltery/casting/casts/ingot_cast
One of the mod's own cast recipes.
Basic alloys
Once you can melt metal, the alloy recipes open up. These are the mod's own recipes and the pack leaves them as they are:[6]
- Molten Brass: makes 180 per alloy batch.[6]
- Molten Bronze: makes 360 per alloy batch.[6]
- Molten Constantan: makes 180 per alloy batch.[6]
- Molten Electrum: makes 180 per alloy batch.[6]
- Molten Invar: makes 270 per alloy batch.[6]
Brass as an example of an unchanged mod alloy.
Pack-tuned alloys
This is where the pack departs from the mod. The steel alloy is changed by the pack, so do not rely on a default recipe from elsewhere. Obsidian and enderium alloys are added by the pack.[6]
Changed by the pack: it makes 90 Molten Steel.
Alloy (hephaestus)
Recipe id: hephaestus:smeltery/alloying/obsidian
Pack-added: makes 288 Molten Obsidian.
Alloy (hephaestus)
Recipe id: hephaestus:smeltery/alloying/enderium
Pack-added: makes 180 Molten Enderium.
Molten Netherite has a mod alloy recipe that makes 360 per batch. The pack also adds melting recipes that produce it from Molten Blaze, covered below.[6]
The mod's netherite alloy, unchanged by the pack.
Cobalt
Cobalt is cast rather than alloyed. A casting table turns Molten Cobalt into a Cobalt Ingot or a Cobalt Nugget, and a casting basin makes a Block of Cobalt. All of these are mod recipes.[6]
Casting Basin (hephaestus)
Recipe id: hephaestus:smeltery/casting/basin/metal/cobalt/block_cast
Casting basin recipe for the cobalt block.
Late game: Molten Blaze melting
The pack adds a large set of melting recipes. Netherite parts and the diamond, emerald and iridium ore melting recipes use Molten Blaze as their only mod input. In the dump, 254 melting recipes use it and they make 19 different results. Gold and iridium tool parts that are written out use lava instead.[6]
Melting (hephaestus)
Recipe id: ftb:hephaestus_materials/melting/netherite/nugget
Pack-added: makes 10 Molten Netherite.
Melting (hephaestus)
Recipe id: ftb:unification/hephaestus/smeltery/melting/ore/diamond
Pack-added: makes 90 Molten Diamond.
Clear glass
Clear Glass is made by a stonecutting recipe the pack adds. Clear Stained Glass and Tinted Clear Glass come from the mod's own shaped crafting recipes.[6]
Pack-added stonecutting recipe.
How does Hephaestus Forge work with other mods?
4 parts
The quest book in this pack does not cover Hephaestus Forge, so its links to other mods show up in recipes instead. In practice, the casting table and casting basin turn molten metals and gems into items from many other mods, and the pack adds a few recipes of its own on top.[2]
Casting other mods' materials
The pattern is consistent across the mod recipes in the list below: 90 units of a molten material make one ingot or gem on a casting table, 10 units make a nugget, and 810 units make a block in a casting basin.[2]
- Applied Energistics 2 and Extended AE: Molten Certus Quartz casts into Certus Quartz Crystal, Molten Fluix into Fluix Crystal, and Molten Entro into Entro Crystal.[2]
- Ender IO: Molten Conductive Alloy makes a Conductive Alloy Ingot or a Conductive Alloy Nugget on the table, or a Conductive Alloy Block in the basin. Molten Dark Steel casts into a Dark Steel Block.[2]
- Ender IO: Evolution: Molten Energetic Silver casts into Energetic Silver Ingot, Energetic Silver Nugget and Energetic Silver Block. Molten Vivid Alloy casts into a Vivid Alloy Block.[2]
- Energized Power: Molten Crystallized Alloy and Molten Energized Alloy cast into Crystallized Alloy Ingot and Energized Alloy Ingot. Molten Advanced Alloy casts into a Block of Advanced Alloy.[2]
- FTB Armory: Molten Adamantite casts into an Adamantite Ingot (90 units), an Adamantite Gear (360 units) or an Block of Adamantite (810 units). Molten Aeternium casts into an Block of Aeternium.[2]
- FTB Materials: Molten Dimensional Shard casts into a Dimensional Shard Gem or a Block of Dimensional Shard, and Molten Ruby casts into a Block of Ruby.[2]
- Occultism: Molten Spirit Attuned makes a Spirit Attuned Gem or an Block of Spirit Attuned Gem, and Molten Iesnium makes an Iesnium Ingot or an Block of Iesnium.[2]
- Oritech: Molten Fluxite casts into Fluxite or Block of Fluxite, and Molten Adamant casts into an Adamant Ingot or an Block of Adamant block.[2]
- Ars Magica: Legacy: Molten Moonstone and Molten Topaz cast into Moonstone and Topaz, or into Block of Moonstone and Block of Topaz.[2]
- LTX Industries: Molten Olivine casts into Olivine, Molten Niobium into Niobium Ingot or Block of Niobium, and Molten Slatesteel into a Block of Slatesteel.[2]
- Other single-mod links: Stellaris (Desh Ingot and Desh Block), Neo Vitae (Hellforged Ingot and Hellforged Block), EvilCraft (Dark Gem and Dark Block), CakeStickLib (Wrought Iron Ingot, nugget and block), Nodeworks (Celestine Shard), XyCraft World (Blue Xychorium Gem), Iron's Gems 'n Jewelry (Garnet and Onyx) and Just Dire Things (Blazegold Ingot and Eclipse Alloy Ingot).[2]
Recipes the pack changed
Three casting recipes from other mods are marked as changed by the pack: the Advanced Alloy ingot cast from Molten Advanced Alloy, and the Block of Enderium and Enderium Gear casts from Molten Enderium. All three produce FTB Industrial Contraptions items. Check the recipe viewer for the exact in-pack amounts rather than assuming the mod defaults.[2]
Recipes the pack adds
The pack also adds its own recipes that use Hephaestus fluids. Casting Molten Gold on the table makes Hephaestus Tools parts: 180 units for an Adze Head, and 720 units each for a Broad Axe Head and a Hammer Head. Molten Netherite (10 units) casts into an Netherite Nugget, and Molten Steel (90 units) casts into a Steel Plate.[2]
Casting Table (hephaestus)
Recipe id: ftb:justhammers/destructor_core
The Destruction Core from just-hammers is cast from molten diamond on a casting table.
Casting Table (hephaestus)
Recipe id: ftb:justhammers/diamond_destructor_hammer
The finished Diamond Destructor Hammer is cast from molten diamond too, using 2,430 units.
The pack adds melting recipes that turn Molten Blaze into other fluids. 50 units of molten blaze make 90 units of ftb:molten_adamantite for an ingot-sized recipe, 10 units for a nugget-sized one and 810 units for a block-sized one. The same 50 units also make 90 units of Molten Awakened Supremium or 90 units of Molten Insanium, which links to Mystical Agradditions.[2]
Clear glass and Connected Glass
A pack script adds Clear Glass to the same glass block tag as the clear and borderless glass from Connected Glass, so those blocks are grouped together for tag-based checks.[5]
