Use

A Kettle is used for reducing various liquids by boiling.

There are two methods used for the kettle:

• Non-stoked - load with requirements including wood, leave until complete.
• Stoked - load with requirements, stoke with wood and ignite, continue to add wood/stoke as it burns down until the liquid is boiled off. For stoked runs (see details below), you will need 28 wood per kettle (assuming no mistakes), with the total process taking about 14 teppy minutes (30 teppysec per tic).

Stoking

In general terms, it works as follows:

• Once the kettle is ignited, it runs in a series of 30-teppysecond ticks. At the beginning of each tick, it consumes one deben of wood. At the end of the tick, it evaporates one deben of water. (Meaning that most of the time, except for the very beginning and end of the batch, it will consume one wood and one water simultaneously every 30 tsec.)
• The first three ticks after igniting are "warm-up" ticks... wood is consumed, but no water is evaporated.
• If at the beginning of a tick there is no wood left under the kettle, the fire goes out. The batch isn't ruined, but the fire will have to be reignited, and will go through the warm-up process again, wasting time and wood.
• You can stoke the kettle at any time to add wood, but it will only hold up to 5 at once.
• In total you will need 28 wood per kettle (assuming no mistakes).
• Total process takes about 14 teppy minutes (30 teppysec per tic).
