If you want more powerful tools, that are for example made of metal, you will need to turn to a smeltery.
Grout
This block is needed to make seared bricks and is crafted with clay, sand and gravel.

Seared Brick
This item is used to make Seared Bricks, or components for the smeltery.

Seared Bricks
This is mainly a decorative block, and its appearance can be changed by placing it in the stonecutter.

Seared Tank
This is used to store lava and molten metals.

Seared Gauge
This is also used to store lava and molten metals.

Seared Melter
This is a compact, early-game method of melting metals.
Requires either a Seared Melter or a Seared Tank/Gauge with lava beneath it to power it.

Seared Heater
This is placed beneath a Seared Melter to power it. Uses coal and charcoal.

Each coal/charcoal piece equates to 4 smelts, while the Melter can only hold 3 ingots worth of fluid at a time.
Requires copper cans/buckets to transfer fluid.
This is what it should look like.

Smeltery Controller
This block is the main component needed for a smeltery and requires one lava bucket to activate it, allowing for 10 smelts.
It can melt everything that the Seared Melter can, but more materials can be gathered from this process, with raw metals doubling, and it can also alloy.
Now, it no longer has a crafting UI as you simply interact with each material you want to smelt.

Copper Can
This new item is very useful for transferring molten fluids around, holding one ingots worth per can, while buckets now hold two ingots worth.
To use, scoop from the Seared Melter, or from the centre of the Smeltery.

Casting Table
This is vital for making metal tool parts and is essentially an upgraded part builder.
Each cast's material cost offers a guide on how much fluid is needed to fill it.
Requires copper cans/buckets or a seared faucet to fill.


Casting Basin
This is a much faster way of getting metal blocks than the casting table. It uses 9 cans (4.5 buckets) of a molten metal to make a block. It also has other uses (i.e. Lavawood).
Requires copper cans/buckets or a seared faucet to fill.

Seared Faucet
Instead of needing to rely on copper cans and buckets to cast with materials, you can now pour out of your smeltery with seared faucets!

Seared Drain
This is the base block a faucet rests on to be able to be used with the smeltery.


Smeltery Model
Building a smeltery requires to have a 3x3 bottom, with 3x1 walls surrounding it.
Activate it by either pouring lava directly into the controller, or having a tank in the opposite corner.
Like the melter, interact with the material you want to smelt, and it will be added the smeltery.
