Understanding the Minecraft Comparator Clock
Before we jump into the efficient furnace, let’s understand the star of the show: the minecraft comparator clock. In its simplest form, a comparator clock is a repeating Redstone circuit that pulses on and off at regular intervals. Comparators, in general, are incredibly versatile Redstone components with multiple functions, but in this context, we’re leveraging their ability to maintain a signal based on the presence of items in a container, and to create a clock circuit when combined with other components.
A basic comparator clock typically involves a comparator, some Redstone dust, and a block. The comparator reads the signal from a container (like a dropper or chest) and outputs a signal. This output is then looped back into the comparator’s input, creating a continuous, pulsing circuit. By adjusting the length of the Redstone dust path or adding repeaters, we can control the speed of the clock, making it faster or slower as needed for different Redstone mechanisms.
In our efficient furnace design, the comparator clock plays a crucial role in precisely controlling the item input, ensuring that only the desired batch size is processed before fuel is added. This precise control is what makes the furnace “100% efficient,” eliminating wasted fuel.

The 100% Efficient Furnace: How It Works in Detail
The “100% Efficient Furnace” operates on a principle of batch processing. It waits until a specific number of items (in this case, eight, to perfectly match the cooking capacity of one piece of coal or charcoal) are queued up before introducing a single piece of fuel. This eliminates the common inefficiency of burning fuel while the furnace is empty or only partially loaded. The system works in three key stages, all orchestrated by our clever use of Redstone and the minecraft comparator clock:
- Precise Item Queuing: Using the comparator clock, we ensure exactly eight items are fed into the furnace’s input buffer.
- Single Fuel Delivery: Once the item queue is full, a single piece of fuel is dispensed into the furnace.
- Automated Reset: After the items are cooked and removed, the system automatically resets, ready for the next batch.
Let’s break down each of these stages to understand how the minecraft comparator clock and other Redstone components work together.
Item Queuing with the Comparator Clock
The item queuing mechanism is where the minecraft comparator clock truly shines. It controls two droppers: a “feeder dropper” that contains the items to be cooked, and a “counter dropper” that acts as our item counter. The comparator clock is wired to activate both droppers repeatedly.
The counter dropper is initially loaded with eight items. As the clock pulses, both droppers dispense items. The feeder dropper sends items into a buffer chest, which then feeds into the furnace via a hopper. Simultaneously, the counter dropper dispenses its items into an adjacent hopper.
The comparator, positioned next to the counter dropper, plays a key role in the item counting process. As long as items remain in the counter dropper, the comparator remains active, powering the adjacent block and deactivating the Redstone torches.
A comparator is placed next to the counter dropper, reading its inventory. As long as there are items in the counter dropper, the comparator outputs a Redstone signal, keeping two Redstone torches deactivated. When the counter dropper becomes empty (after dispensing all eight items), the comparator’s signal turns off, allowing these Redstone torches to activate.
One of these torches is strategically placed to cut power to the comparator clock itself. This stops the clock and, crucially, halts the feeder dropper from sending any more items. Because the counter dropper started with exactly eight items, precisely eight items will have been dispensed by the feeder dropper into the buffer chest.
The buffer chest is a clever addition. It allows the furnace to handle batches of mixed items. Without it, if the feeder dropper fed directly into the furnace, you would be limited to cooking only one type of item at a time. The buffer allows you to input up to eight different items, which will then be cooked efficiently in a single fuel cycle.
The buffer system, comprised of a chest and hopper, is essential for the versatility of the 100% Efficient Furnace. It allows for queuing different types of items, not just a single kind, for efficient batch cooking.
Single Piece Fuel Delivery
The same Redstone signal that deactivates the comparator clock also triggers the fuel delivery system. Another dropper, the “fueling dropper,” is positioned to feed fuel (coal or charcoal) into the side of the furnace. When the comparator clock stops (because the counter dropper is empty), the activated Redstone torch powers the fueling dropper, causing it to dispense a single piece of fuel into the furnace. This ensures fuel is only added when there are items ready to be cooked, maximizing efficiency.
The activation of Redstone torches upon the counter dropper emptying is the trigger for the fueling system. One torch, in particular, activates the fueling dropper, ensuring a single piece of coal or charcoal is deposited into the furnace at the perfect moment.
Automated Reset Mechanism
The reset mechanism is crucial for making this furnace fully automatic. After the eight items are cooked, and the furnace is empty, the system needs to reset the item counter (the counter dropper) to prepare for the next batch.
Here’s how the reset works: The hopper that receives items from the counter dropper initially holds those items. It’s prevented from passing them further down the line by a Redstone torch. Once the counter dropper is empty, and the comparator deactivates, the Redstone torch controlling this hopper is also deactivated. This allows the eight counter items to move into the next hopper in the chain.
This Redstone torch plays a control role, initially preventing the hopper from transmitting items and holding the counter items in place until the reset sequence is triggered.
The deactivation of this Redstone torch, triggered by the empty counter dropper, is the signal for the counter reset to commence, allowing items to flow again.
These eight counter items are then fed into another hopper. This hopper’s output is blocked by another Redstone torch, which is controlled by a comparator monitoring the furnace. As long as there are items in the furnace (meaning cooking is in progress), this Redstone torch remains active, blocking the hopper.
A comparator attentively monitors the furnace’s status, detecting whether it contains any items and playing a crucial role in the reset timing.
Once the furnace finishes cooking and is emptied (all cooked items are pulled out by the output hopper), the comparator next to the furnace no longer detects items. This turns off the Redstone torch blocking the hopper, allowing the eight counter items to flow through one final hopper and back into the counter dropper. This refills the counter dropper with eight items, restarting the whole process with the minecraft comparator clock initiating a new cycle of item counting and fuel delivery.
The signal from the furnace comparator is carefully routed and delayed, ensuring precise timing for the reset mechanism to function correctly and efficiently.
This Redstone torch is key to holding back the counter items as long as the furnace is active, preventing premature resets and ensuring the furnace cycle completes properly.
The 14-tick delay in the reset circuit (achieved using repeaters) is critical. It ensures that all eight counter items have fully transferred through the hoppers before the system restarts. Without this delay, the timing might be off, and the counter might reset prematurely, leading to incorrect item counts.
Step-by-Step Guide: Building Your 100% Efficient Furnace
While there might be more compact designs, this efficient and reliable build measures 5 blocks wide, 5 blocks tall, and 7 blocks deep. Follow these layer-by-layer instructions to construct your own.
Layer 1: The Collection Layer
This is the base layer and the simplest. Place a chest, and then place a hopper feeding into the chest. This chest will collect all your efficiently cooked items.
Layer 2: Furnace and Fuel Delivery
Layer two is where things start getting more complex. Place a furnace directly above the hopper from layer one. On one side of the furnace, place a dropper facing into the furnace (this is your fueling dropper). You can place a slab or a solid block behind the fueling dropper; it’s not critical. Optionally, place a hopper feeding into the fueling dropper for easier fuel loading.
Behind the furnace, place three blocks in a row. Place a comparator facing away from the furnace (it should be monitoring the furnace). Place a repeater coming out of the comparator, and then Redstone dust leading away. This is the start of the furnace monitoring circuit for the reset.
Pay close attention to the repeater delays in this layer. Three repeaters need to be set to 4 ticks (full delay), and one repeater to at least 2 ticks for the circuit to function correctly.
Layer 3: Hopper Loop and Counter Dropper
On layer three, directly above the furnace, place a hopper. This hopper will feed items into the furnace. Above and slightly behind the furnace, place the counter dropper, facing away from the furnace. Arrange hoppers in a counter-clockwise loop: one hopper to the left of the counter dropper feeding into the counter dropper, and another hopper connecting the output of the counter dropper to the input of the first hopper in the loop.
Layer 4: Feeder System and Comparator Clock Foundation
Place a chest above the hopper that is above the furnace. This is your buffer chest. Next to this chest, place the feeder dropper facing into the chest. This dropper will feed items into the buffer.
Now, build the base of the minecraft comparator clock. Place a block next to the counter dropper. Place a comparator facing away from the counter dropper, monitoring its inventory. Place a repeater coming out of this comparator. Set this repeater to 3 ticks delay.
It’s recommended to use a slab for the block next to the counter dropper (above the hopper feeding into it). While not strictly essential, it can smooth out item flow by preventing intermittent deactivation of the last hopper in the chain by the comparator clock signal.
Using a slab above the hopper can improve the smoothness of the item flow within the comparator clock mechanism, though it’s not strictly mandatory for functionality.
Layer 5: Completing the Comparator Clock and Input Hopper
The final layer completes the minecraft comparator clock. Place three pieces of Redstone dust to finish the clock circuit, connecting the repeater from the comparator back to the dropper. Finally, place a hopper feeding into the feeder dropper. This is your input hopper where you’ll load items to be cooked. You can place this hopper next to or above the feeder dropper, as preferred.
