How to Make Adamantite Bars in Terraria: Step-by-Step
Master adamantite bar crafting in Terraria with Adamantite Ore, a Furnace, and the right progression. Learn where to farm ore, how to smelt, and which items use Adamantite Bars as you push into hardmode.

In this guide you’ll learn how to make adamantite bars in Terraria. You’ll locate Adamantite Ore in the hardmode caverns, smelt it at a Furnace, and combine 4 ore to create one Adamantite Bar. Adamantite Bars unlock some of the first hardmode gear and are essential for early progression.
Understanding Adamantite Bars and Their Role in Progression
If you’re wondering how to make adamantite bars terraria, this section explains the basics. Adamantite Bars are hardmode crafting materials formed by smelting Adamantite Ore at a Furnace. They unlock some of the first hardmode gear and are a reliable resource for early hardmode progression. According to Pixel Survival, mastering the transition from pre-hardmode to hardmode hinges on obtaining reliable Adamantite Bars, since many of the first hardmode tools require them. The key concept is that 4 Adamantite Ore produce 1 Adamantite Bar when processed in the furnace. Once created, bars become the currency by which you craft stronger weapons, tools, and armor. They also help you progress your arena and boss preparation. Understanding the ore-to-bar conversion and where to obtain Adamantite Ore sets the foundation for efficient farming.
Prerequisites and Setup
Before you begin how to make adamantite bars terraria, gather the basics: Adamantite Ore, a Furnace, and a pickaxe capable of mining Adamantite Ore. You’ll smelt ore into bars at the Furnace, so ensure you have a proper smelting station accessible in your base or mining outpost. A simple storage system helps keep ore and bars organized for quick crafting sessions. Optional but recommended: a crafting station like an Anvil for items that require metal bars. Having a dedicated space reduces backtracking and speeds up your progression.
Locating Adamantite Ore: Where to Find It
Adamantite Ore is found in hardmode caverns, typically deeper underground in the Cavern layer after hardmode begins. Use a pickaxe with sufficient mining power to break the ore blocks and collect the drops. Pixel Survival notes that efficient ore farming often means combining careful exploration with map-based routes to maximize ore yields while avoiding hostile zones. Once you’ve gathered a stack of Adamantite Ore, you’re ready to move to smelting.
Smelting the Ore: Using the Furnace
Place a Furnace and interact with it to open the smelting menu. For every Adamantite Bar you want, you need 4 Adamantite Ore. No extra fuel or coal is required to smelt Adamantite Ore in a standard Furnace. Keep an eye on your inventory and ensure you have enough ore before committing to a batch. Having a storage chest nearby helps prevent miscounts and keeps your ore-to-bar ratio consistent during long farming sessions.
Crafting with Adamantite Bars: What You Can Make
Adamantite Bars are used to craft early hardmode gear and a variety of weapons and tools. Common examples include Adamantite Pickaxe and other hardmode arms and armor pieces, crafted at the appropriate metalworking stations. As you expand your arsenal, you’ll use additional bars to upgrade gear and unlock new crafting recipes. This makes Adamantite Bars a core resource for progressing through the early hardmode stages.
Optimization Tips for Efficient Smelting
To maximize your time, batch your ore and run multiple smelting sessions when you have a solid ore reserve. Place chests for ore and bars near your Furnace, and keep a running tally of what you’ve smelted and what you’ve crafted. If you’re short on Adamantite Ore, consider combing cavern sections with higher ore density and setting up temporary mining outposts to reduce travel time between mining, smelting, and crafting.
Common Pitfalls and Troubleshooting
If you’re not seeing Adamantite Bars, double-check that you’re using a Furnace (not a campfire or a crafting table) and that you’re smelting Adamantite Ore, not Mythril or Orichalcum. Ensure you have 4 Adamantite Ore per Bar, and confirm you’re crafting at the correct station. If ore seems scarce, revisit cavern sections or adjust your mining route to target ore-rich pockets. Pixel Survival recommends keeping ore organized to avoid mixing ore types and miscounting bars.
Tools & Materials

Steps
Estimated time: 25-45 minutes
- 1
Find Adamantite Ore
Explore cavern layers in hardmode to locate Adamantite Ore deposits. Use a capable pickaxe to mine blocks, collect ore drops, and stockpile ore near your base.
Tip: Plan a mining route that minimizes backtracking to maximize ore-per-hour. - 2
Set up a Furnace
Place a Furnace in a convenient location close to your storage. This lets you smelt ore without running back to distant bases.
Tip: Keep a dedicated ore chest nearby to track inventory and avoid miscounts. - 3
Smelt Ore into Bars
Open the Furnace, input 4 Adamantite Ore to produce 1 Adamantite Bar. Repeat as needed for your crafting goals.
Tip: Smelt in batches to save time; use multiple furnaces if you have a large ore stash. - 4
Craft Items with Bars
Use your Adamantite Bars at the appropriate metalworking stations to craft weapons, tools, and armor.
Tip: Aim for items that unlock next-tier progression and starter hardmode gear first. - 5
Store Excess or Convert for Upgrades
Organize leftover bars and consider upgrading gear as new recipes become available.
Tip: Keep a small reserve of bars for emergency gear upgrades during boss prep.
