Kiln

The Kiln is a temperature-controlled crafting machine that produces valves using glass and metal. It uses an energy-based heating system with fuel progression - more advanced valves require hotter temperatures and better fuels.

How It Works

The Kiln operates on a temperature and energy system:

  1. Add fuel - Coal, lava buckets, blaze rods, etc.
  2. Temperature rises - Fuel burns and heats the kiln
  3. Craft valves - Place materials and glass/sand in crafting pattern
  4. Glass melts - Kiln melts glass internally during crafting
  5. Energy consumption - Recipes consume energy over time
  6. Maintain temperature - Better fuels sustain higher energy recipes

Key mechanics: - Temperature derived from internal energy - Recipes require minimum temperature (1200°C) - Different fuels burn at different rates - Advanced recipes need premium fuels to maintain temperature

Using the Kiln

Basic Operation

  1. Place kiln in your workshop
  2. Right-click to open GUI
  3. Add fuel to fuel slot (bottom left)
  4. Wait for heating - temperature rises to operating point (1500°C)
  5. Place pattern - Arrange metal + redstone in crafting grid
  6. Add glass/sand - Kiln melts it internally (1 block → 1000mb → 4 recipes)
  7. Crafting begins - Progress bar shows completion (uses 250mb molten glass)
  8. Collect output - Valves appear in output slot

Fuel Requirements

Different valve tiers require different fuel quality:

Tier 1 (Coal sufficient): - Copper Valve - 40 energy/tick - Tin Valve - 60 energy/tick

Tier 2 (Coal at limit): - Iron Valve - 100 energy/tick - Bronze Valve - 140 energy/tick

Tier 3 (Blaze rod/lava needed): - Gold Valve - 180 energy/tick - Apatite Valve - 200 energy/tick

Tier 4+ (Lava recommended): - Diamond Valve - 240 energy/tick - Emerald Valve - 280 energy/tick - Netherite Valve - 400 energy/tick - Blazing Valve - 440 energy/tick (maximum)

Fuel Types

Wood/Planks: - Burns fast, low energy output - Cannot sustain valve recipes (too weak)

Coal: - Standard fuel for early valves - Works for copper, tin, iron - Struggles with bronze (140 energy/tick) - Fails at higher tiers

Blaze Rods: - Mid-tier fuel - Sustains gold, apatite valves - Still insufficient for highest tiers

Lava Buckets: - Premium fuel source - Required for diamond, emerald, netherite valves - Maximum burn rate ~75 energy/tick net capacity - Barely sustains blazing valve (440 demand vs ~315 capacity)

Temperature Behavior

Operating setpoint: 1500°C Crafting minimum: 1200°C Maximum theoretical: 2000°C

What happens: - Fuel burns → energy increases → temperature rises - Recipe active → energy drains → temperature may drop - If temperature falls below 1200°C → crafting pauses - Add better fuel → temperature recovers → crafting resumes

Natural progression: - Low-tier recipes work with any fuel (just slower) - High-tier recipes require premium fuels or they stall

Glass Requirements

All valve recipes require 250mb of molten glass.

Using glass: - Add glass blocks or sand directly to the kiln - Each block produces 1 bucket (1000mb) of molten glass when melted - One glass block = enough for 4 valve recipes - Kiln melts it internally during crafting - No external smelting or fluid infrastructure needed

Tips

  • Start with coal for copper/tin valves
  • Upgrade to lava buckets for advanced valves
  • Watch temperature gauge - if it drops, crafting pauses
  • Better fuels = faster, uninterrupted crafting
  • Keep spare fuel on hand for continuous operation
  • Stock glass blocks or sand for valve crafting

Common Patterns

Early kiln setup: 

[Kiln] + Coal → [Copper/Tin Valves]

Advanced setup: 

[Kiln] + Lava Bucket → [Diamond/Emerald/Netherite Valves]

With glass storage: 

[Sand/Glass blocks] → [Kiln] → [Valves]

Troubleshooting

Crafting paused/temperature dropping: - Fuel is insufficient for recipe energy demand - Upgrade to better fuel (coal → blaze rod → lava) - Low-tier recipes will complete eventually, just slowly

No glass available: - Need glass blocks or sand to start crafting - Add glass/sand directly to the kiln GUI - No pre-smelting required

Pattern not accepted: - Check recipe pattern (materials + redstone configuration) - Ensure glass/sand is available - Verify minimum temperature reached (1200°C)
