The 
Kiln is the first building in Graveyard Keeper 2 that works while you are somewhere else, which makes it the first one you stand next to wondering why it has stopped.
It is four 
Piece of stone, five 
Clay and five 
Water, none of which needs a kiln to make, and it fires three different things rather than the one everybody builds it for.
It fires three things, and two of them come off the wheel
Brick is the one everyone knows: four Clay and twenty 
Fuel for six bricks. The other two slots take pottery that has already been shaped somewhere else.
A 
Clay Plate is two Clay at the 
Potter’s Wheel for three, and three of those fired with ten Fuel give three Ceramic Plate. A 
Clay Urn is four clay for two, and two urns with fifteen fuel give three Ceramic Urn.
The plate line multiplies at the wheel and holds at the fire: two Clay make three plates, and three plates fire into three Ceramic Plate. Two clay for three finished plates is the best return on clay in the game.
The urn line does it the other way round. Four clay make only two Clay Urn, then the fire turns those two into three Ceramic Urn, so an urn costs twice what a plate does.
Fifteen seconds a tick, and mastery cannot move it
The kiln is an automatic station. It charges no energy at all, and the tick length is fixed at fifteen seconds whatever your mastery, which the window prints in its own header.
That makes a batch of six bricks exactly two minutes. A plate firing is seventy five seconds and an urn firing ninety, and none of those numbers changes however good you get.
Building mastery is what the kiln measures, and it gates rather than speeds. Bricks and plates want three, urns want five, and past that the extra does nothing at this building.
Fifteen seconds is also what both furnaces, the Distillation Cube and the crematoriums run at. The kitchen ovens are the fast ones, at ten seconds and five.
It stops after every batch and waits to be emptied
This is the part that sends people looking for a bug. All three kiln recipes finish their batch, hold the output in the building and refuse to start the next one until somebody takes it away.
Seventy six of the two hundred and thirty eight automatic recipes in the game behave that way, and the kiln has three of them. A kiln left alone overnight has made six bricks.
Put a hauler in the same zone and the output is cleared as it appears, so the kiln runs continuously instead of once. Nothing else about the building changes.
Queueing helps too, because a queued batch starts the moment the previous output is gone rather than when you next walk past.
The fuel bill, in logs
Twenty Fuel a brick batch works out at one 
Firewood for every three bricks, since two firewood make twenty fuel at a shed. Six bricks cost two logs and two minutes.
The ceramics are cheaper to fire and dearer in clay. Ten fuel for three Ceramic Plate and fifteen for three Ceramic Urn are both under what a brick batch burns, so the constraint on pottery is the Potter’s Wheel ahead of it rather than the fire.
Graveyard Keeper 2 Kiln FAQ
How do you build a Kiln in Graveyard Keeper 2?
Four Piece of stone, five Clay and five Water, unlocked by Brick Making. None of the materials needs a kiln, so it is meant to be one of the first production buildings you own.
What can the Kiln make?
Three things. Bricks from four Clay and twenty Fuel, Ceramic Plates from three Clay Plates and ten Fuel, and Ceramic Urns from two Clay Urns and fifteen Fuel. The plates and urns are shaped at the Potter’s Wheel first.
Why has my Kiln stopped?
Because it finished a batch and is holding the output. All three of its recipes wait until the previous batch is collected before starting the next one, so a kiln with nobody emptying it makes exactly one batch.
How long does a brick take?
Two minutes for six. The kiln ticks every fifteen seconds and a brick batch is eight ticks, and no amount of mastery makes that faster.
What mastery does the Kiln need?
Building. Bricks and Ceramic Plates need three and Ceramic Urns need five. Above that the number does nothing here, because the tick length is fixed.
How much Fuel does a Kiln use?
Twenty for a brick batch, which is two Firewood, so roughly one log for every three bricks. Plates cost ten and urns fifteen.
