Flux Forge

A Flux Forge smelts ore three at a time, faster than a blast furnace and without coal — on the flux of the land; it has work of its own too: recycling worn metal, opaline and flowstone. Build a cube three blocks to a side: copper at the eight corners, a Magma Block at the heart, a Copper Grate in the middle of the front — the tap grate — and in the middle of the top — the throat; Flowstone Bricks everywhere else. A pinch of quickdust on any of its blocks — the copper binds the masonry, veins of flux show in the seams, and the magma wakes as the heart of the forge.

Throw ore onto the top of the forge or feed it into the throat with a hopper: the forge melts three things at once, faster than a blast furnace, and gives the result out of the tap grate — into a chest or hopper set in front of it, or onto the ground if the way is free; behind a wall the result waits inside for pipes. Break any block of the forge, and it falls apart into what it was built from.

By itself the forge grants no luck: without additives there are no extra ingots. Instead, with every third ore Current Slag runs into the tap grate — dark glass that remembers its ore. Dissolve it in a Crucible, and the ore gives up its currents. If the land runs dry, the forge smolders and waits for flux.

The forge also has work of its own that no furnace knows. Worn-out metal — a sword, a pickaxe, mail, horse armor — flows again: the forge gives back nuggets, less than half of what went into the thing, and fewer still from a worn one. Enchantments do not pass on, the work takes twice as long, and every third thing leaves Slag that remembers it. What was bought from a villager the forge melts like a furnace: into one nugget.

An opal nodule opens whole in the heat of the forge and gives two layers of Opaline — a furnace takes only one. Dripstone grew drop by drop, Flowstone grew in a stream: the forge drives the flux of its land through a Dripstone Block, and veins rise in it. This spends flux generously.

Additives are currents in the forge: more from ore, faster smelting, tempered gear. Pour them by a siphon over the top or a vial on the forge: up to 32 parts of each (four vials), a part for every item.

Prism

More from ore — Prism: raw ore gives one more three times in four (2 parts; a stack becomes nearly 1¾), an ore block always (3 parts; a stack becomes two). No luck for concentrate or scrap.

Ember

Faster — Ember, a part per item: twice as fast, up to four times with bellows.

Gale

Wind for bellows — Gale, a part per item: the bellows blow as on Gale and can blow iron; where Gale flows, each adds another third of the pace.

Edge

More metal from scrap — Edge, 2 parts per item: 60% of the recipe metal, not 45%. Bought gear still gives one nugget.

Gleam

Flux to the land, not Slag — Gleam, a part per ore or scrap: instead of Slag, up to 4 flux to the land, never more than the forge took.

Halo

A cleaner chunk — Halo, a part per item while the chunk is murky: each item clears a unit of murk.

EmberTide

A gamble — Ember with Tide, a part of each per ore: half the ores give triple, a quarter double, a quarter is lost and fouls the chunk; on average like Prism.

PrismGleam

Cheaper gems — Prism with Gleam: a gem ore block always gives one more for 2 Prism and 1 Gleam, not 3 Prism.

Rime

Sturdier gear — Rime, 4 parts per item: an iron, gold, copper or fluxsteel tool or armor piece comes out of the forge whole instead of as scrap, with a quarter more durability than usual. Only once: tempered gear comes out as it went in. While Rime is in the forge, such things are not melted — they wait to be tempered.

RimeEmber

Hardening — Rime with Ember together: heat, then cold, as a smith does it — half again the usual durability, for one more part of Ember.

Mind

More experience — Mind, a part per item: smelting ore and anything furnaces smelt gives twice the experience.

MindEdge

Master's memory — Mind with Edge: enchanted scrap gives back its enchantments' experience, as a grindstone would — a part of Mind per item.

Tempo

Scrap and tempering twice as fast — Tempo, a part per long item: long work fits into an ordinary cycle.

Strata

Smelting on dry land — Strata, a part for every 2 flux an item takes: the forge drinks land from the vial and takes no flux from the chunk. Gleam then has nothing to give back to the land.

StrataPrism

A vein — Strata with Prism: Strata gives the ore back its stratum, and raw ore and ore blocks alike always give one more for 2 Prism.
