I just want a basic rundown on how they work.
I've put wood blocks in and it's trickling tar out slowly
How much tar does 1 block make?
How does it make charcoal?
How long does it take now that it's been fixed?
EDIT:
What you were probably looking for:
Tar per block: most ~.1L, spruce ~.2, pine ~.4
Making Charcoal: fuel it up, light it and wait 16 hours for 2-4 pieces of coal per block
How long: 16 hours IRL time for a full burn it seems
Tar Kiln Quality: Does not effect the burnt materials so don't waste good clay on it
Tar Usage: Torches and tar sticks which right now have only a known cosmetic use to make black roofs
Coal Usage: for smelting metals, do not use for regular fuel ticks because it doesn't do much different than you'd think
