Liquid Frost in Valheim: Frigid Kiln Recipe and Uses

Liquid Frost is a material tied to Deep North progression. You obtain it from processing Ice in a Frigid Kiln, and its main role is fueling the Frost Foundry. Use this page alongside the Deep North guide and the item catalog.

Quick facts

How to obtain

1. Explore Winding Tunnels for Frostcores.
2. Build a Frigid Kiln, then load it with Ice.
3. Collect Liquid Frost and transfer it to the Frost Foundry before inserting a cast.

What it's used for

• Fuel the Frost Foundry to finish the Intricate Key.
• Process equipment casts made from dungeon moulds.
• Keep reserve fuel before committing to the Mörkhalla route.

Common mistakes

• Bringing a finished mould to the foundry without first making a cast.
• Assuming Liquid Frost replaces the recipe materials used at the Black Forge.

Mining and processing loop

Mine Ice from Deep North ice sheets with a Black Metal pickaxe. The movement cue is sliding: when your character starts to skid, you are standing on mineable ice rather than ordinary snow. Clear nearby enemies before swinging, because a fight on the slick surface makes stamina management and retreat harder.

Build the Frigid Kiln with 10 Frostcores, 20 Stone, and 5 Ice. Each kiln cycle consumes five Ice and produces one Liquid Frost. A cycle takes about 30 seconds, so stage several loads near the kiln rather than making a new mining trip for every cast.

Liquid Frost is consumed as fuel by the Frost Foundry while it processes each prepared cast. It is not part of the Black Forge recipe: the mould and metal make the cast first, then foundry fuel finishes it. Keep at least one unit ready before crafting an Intricate Key cast so the consumed mould does not leave you waiting on another ice expedition.

Liquid Frost can pass through portals, so the kiln and foundry do not need to share a vulnerable Deep North camp. Process Ice at a secure base and distribute coolant to any workshop that holds casts. Label it as foundry fuel so it is not mistaken for a direct crafting ingredient at the Black Forge.

Frequently asked questions

What makes Liquid Frost?

The Frigid Kiln processes five Ice into one Liquid Frost.

Where is Liquid Frost consumed?

The Frost Foundry uses it as fuel while turning prepared casts into finished items.

Can Liquid Frost go through a portal?

Yes. Liquid Frost can pass through a standard portal, so you can operate the Frigid Kiln at a protected base and move its output to another foundry.
