currently in game there are two types of cauldron

Ceramic Cauldron 10 slots with 20 minute cycle
Copper Cauldron. 5 slots with 1 minute cycle

It would be nice to have a Larger sized cauldron that has the reasonably quick timings.
when boiling eggs in the cauldron it feels a little impractical due to the amount of slots available you are unable to set it going for a longer period of time and still have it being efficient.
since you need to have Fuel and Water filling up two of the spaces and at least 1 space for Raw eggs and 1 space for the Boiled Eggs as an output.
so cooking options in a copper Cauldron are only as follows

1 stack fuel (at most 20 cycles if using coal)
1 stack water (50 units will only use up half)
2 stacks Eggs (25x2)
1 space for 25 boiled eggs
takes 13 cycles (13 minutes) to produce 25 Boiled Eggs at which point you have no space

2 stacks of fuel (max 40 cycles if using coal)
1 stack water (50 units will only use up half)
1 stack Eggs (25)
1 space for 25 boiled eggs
takes 25 cycles (25 minutes) to produce 25 Boiled Eggs at which point you have used up the Eggs

Those are the only two useful layouts for Boiling them.
in a Ceramic Cauldron you have 10 slots but each cycle is 20 times longer meaning to produce 21 eggs it takes an hour (having 7 stacks of eggs)
it also uses up 5 units of fuel per cycle ie 5x (1 coal or 3 cuttings or 6 wood or 9 branches) making it even less efficient as 1 stack of fuel can at best can only produce 21 boiled eggs with 7 stacks of eggs 1 fuel and 1 stack of water as you run out of space and waste the last 5 fuel at which point you might get 28 eggs if it doesnt stall but then your out of fuel.

with 6 stacks of eggs to give more space you can get 24 eggs but it takes another 80 minutes and you run out of fuel

with two stacks of fuel it can go for 8 cycles but that means you have to reduce the number egg stacks again so after nearly 3 hours you only come out with 40 Boiled eggs

looking back at historical details Cauldrons would often be made out of Bronze or Cast iron so these could be used as materials for a larger sized cauldron. that would be as efficient as the Copper Cauldron but have more space for the raw materials.

it would also give another use for the Bronze and Cast Iron.
