The tar kiln is used to get coal from wood blocks or boards. It also produces Tar as a byproduct, which you can take out in a bucket or barrel.

How to Use

Fill it with blocks or boards, then light the tar kiln using a torch or other fire source. The tar kiln can hold 80 blocks or 40 boards, and it takes 83.3 RL Hours (1.2% per hour) to burn no matter how much wood is in it. Each block becomes 2 coal, one board equals 1,5 coal.

Quality

Tar Kiln Q = ${\frac {_{q}AvgClay+_{q}AvgStone}{2}}$

Tar and Coal Q = ${\frac {3*_{q}Wood+_{q}TarKiln}{4}}$

The color and amount of smoke produced varies.

Tips

• Due to boards being usually higher quality than blocks, it is recommended to use them for making high Q coal.
• Blocks are lower quality than boards, but they produce more tar.
• When adding blocks/boards to the tar kiln, the quality of the blocks/boards will average after each addition. If you want to make high Q coal, avoid putting in any lower Q blocks or boards. Each additional low Q block/board will bring down Q by 1 at least.
• In World 10, it now takes about ~3.5(83.3 hours) days real-time to finish burning coal.
• In World 10, the kiln must be at least half full to start.
• Different types of wood yield different amounts of tar. Pine blocks yield the most tar, followed by other coniferous trees.
• It takes approx. 2 minutes and 45 seconds to produce 0,01l of tar from pine wood.
• In World 11, higher Q tar kilns finish faster than lower Q kilns.
