Steel Making is the process of carbonizing [[iron]] under high temperatures, for which a new type of furnace building is required.

__TOC__

To produce [[steel]], a player needs an iron [[anvil]], a [[forge]], and a Refactory Cementation Furnace building, which itself will require a [[Mechanical power|pulverizer]].

To build a functioning cementation furnace, the player needs 1 iron door, 2 stone coffin sections and 2 stone coffin lids, 6 refractory brick gratings, 53 refractory brick blocks and a number of dirt or stone blocks to build the coal burning area beneath the furnace structure itself. The minimum raw ingredients for these items are listed below.

*6 iron plates (12 iron ingots)

*8 whole granite, andesite, basalt or peridotite blocks

*228 of each powdered ingredient needed, depending on tier, which is about 4 stacks each

Refactory blocks are important for the steel making process as no other currently available block can withstand the extreme heat necessary to produce [[steel]]. Refractory blocks come in three different tiers, all of which can be used to make the cementation furnace. All refractory brick blocks have a chance to receive damage per use of the cementation furnace smelting process, however, using higher tier blocks will reduce the amount that receive damage per use. Tier 1 has a heat resistance of 90% (1 in 10 chance to break), Tier 2 95% (1 in 20 chance to break), and Tier 3 99% (1 in 100 chance to break). (Tier 3 may actually have a heat resistance of 99.9% and thus a 1 in 1000 chance to break. This information needs verification.)

To produce refractory blocks, stone and ore types specified below need to be crushed in a [[Mechanical power|pulverizer]]. These powders can then be used in the crafting grid together with fire [[clay]] to make unfired refractory bricks. Different compositions of powders are required for the different tiers.

From tier 1 to tier 3, the recipes for raw refractory bricks are as follows:</translate>

Raw refractory bricks need to be baked in a [[Clay Forming#Pit Kiln|pit kiln]] to turn into fired refractory bricks. Those can then be used to craft their tier specific brick blocks and brick grating blocks.

The cementation furnace is a multiblock structure that needs to be built in a specific way to ensure it is functioning as intended. When starting the build of a furnace, the player can {{SneakClick}} the stone coffin with coal or an empty hand to trigger a building help overlay. {{SneakClick}}ing will additionally inform the player about the number of still missing or mis-placed blocks in the structure.

{{Protip

|The direction from where the player accesses the coffin while checking for the overlay will dictate the direction the building overlay is shown. The furnace will always assume that the coffin block the player hits when checking is the one nearest to the future furnace door - regardless if the player accesses from the side of the coffin or from the actual end of it.

Additionally to the refractory blocks, there are some more specialist blocks necessary to build a functioning steel making furnace, namely an iron door and a stone coffin including a coffin lid.

And iron door can either be found in ruins, or crafted out of 6 iron plates. Stone coffins can be made out of [[granite]], [[andesite]], [[basalt]] or [[peridotite]].

#First, place the grate blocks and the coffin. These are the center blocks of the structure. The coffin halves will always be placed with the open side towards the player. As soon as the full coffin is placed - without coffin lid, for now - the player can {{SneakClick}} for the building help.

#The full size of the furnace takes up a 5x5 space that is 6 blocks tall, however, an additional layer below the grates will be required to place fuel in.

#If the structure was build correctly, there will be no further indication of missing or misplaced block when {{SneakClick}}ing the coffin.

Blister steel is the first step of creating steel from iron, and functions the same way an iron bloom does. To heat iron up to the required temperatures to make carbonization possible, the player first needs to build a special furnace structure out of refractory blocks and other specialist blocks.

With a finished refractory furnace build, the next step requires the player to fill the coffin.

One stone coffin will hold a total of 16 iron ingots and 40 fuel pieces - either [[coke]] or [[charcoal]]. {{SneakClick|Place}} down one layer of fuel first, then one layer of iron ingots. Repeat until the coffin is full and will not accept any more items. The coffin should allow 5 layers of fuel with 8 pieces per layer, and 4 layers of iron ingots with 4 ingots per layer.

Once filled, the coffin tool tip will indicate that a coffin lid needs to be placed on top of the coffin. Note that the coffin needs to be filled completely, otherwise the process will not start even if the lid is placed and coal beneath ignited.

After the coffin is closed, the player should leave the burning chamber and close the door. It is not recommended to enter the chamber again in the middle of the smelting process, as the extreme heat inside will cause 5 HP damage per tick if inside while the bricks are still heated. The coffin tool tip will indicate that the process requires fuel to be placed and ignited '''below''' the two grates under the coffin.

Access the underbelly of the furnace as shown above from the side or the back of the furnace. Place fuel in equal amounts on the two spaces directly below the coffin. Each fuel layer on one block takes 2 fuel items, meaning a full layer on both blocks requires 4 fuel items. Charcoal, black coal, anthracite and coke work as possible fuel items.

Damaged refractory brick blocks can be broken to return some of their materials back, similar to a broken bloomery. Grate blocks do not get damaged at the moment, which means there is no sense in making them out of higher tier bricks. In addition, not all of the blocks on the cementation furnace building need to be of the same tier, allowing for use of refactory blocks of a different tier when replacing damaged ones.

When testing out the process in creative or survival, keep in mind that the coffin tooltip might take a few seconds to update correctly from one state to the next, specifically once the player ignites fuel below. The coffin will show the progress in percentages, but again it might take a tick until that progress info is shown correctly. A working furnace will have fire particles inside the burning chamber - which also indicates the danger of stepping inside at that time - as well as smoke rising from the chimney.

{{Protip

|The coffin will retain the progressed reached, even if the coal burns out before the process is finished! This allows the player to start the process with a low amount of fuel, and add further fuel as needed, or log of from a server without fear to loose progress and materials. If using charcoal, exactly 4 full loads of 32 will be enough fuel for a full firing of blister steel ingots.

}}

One firing of 16 iron ingots will reward the player with an equal amount of blister steel ingots.

Blister steel in itself is not yet workable steel, instead it behaves similar to iron blooms, and further refining is necessary. To turn blister steel into steel, it needs to be processed on an iron [[anvil]] either by hand or with the help of a helve hammer.

The design of the Refractory Furnace is a modified version of the Manuel de la métallurgie du Fer, from 1895 [[https://upload.wikimedia.org/wikipedia/commons/2/23/Four_cementation_anglais.jpg]]
