Crucible Construction Guide

The crucible is a multiblock structure that forms the core of the Fire and Flames mod. This guide will walk you through building crucibles of various sizes and configurations.

Basic Requirements

Every crucible requires:

1. Crucible Controller - Can be placed at any position in the side wall
2. Fire Bricks - Form the walls and structure
3. Crucible Window - Same as Fire Bricks, but allows you to view inside the Crucible.
4. At least one fuel provider - Crucible Burner or Crucible Tank
5. At least one drain - For outputting fluids
6. Casting Faucet and Basin - Crafting with fluids

Construction Steps

Step 1: Plan Your Size

Crucibles can be built in various sizes, up to a 23x23x23 (Configurable) We will be making a Crucible with internal size 3x3x3.

Step 2: Foundation Layer

Build the 3x3x3 base of Fire Bricks.

Step 5: Validation

Once complete, the crucible will automatically validate its structure:

• Valid: The controller will activate and show the crucible interface
• Invalid: Check for gaps, missing controller, or structural issues

Troubleshooting

Common Issues

Crucible Won't Form:

• Check that the Crucible Controller is at the bottom center
• Ensure all walls are complete with Fire Bricks
• Make sure there are no gaps in the structure

No Heat Generation:

• Add fuel to Crucible Burners
• Fill Crucible Tanks with lava or other hot fluids
• Check that fuel providers are connected to the structure

Can't Access Fluids:

• Add Crucible Drains to the walls
• Install Crucible Faucets for automatic extraction

Advanced Tips

Multiple Fuel Sources

• Combine burners and tanks for consistent heat
• Different fuel types provide different heat levels, but the highest heat level always applies
• Combining high and low heat fuels improves efficiency while maintaining high heat levels
