Potash is a wood-based product which has applications in farming, as well as production of mid- and high-end glass products.
Producing potash[edit]
Potash can be created at an ashery by a dwarf with the potash maker labor enabled. This process requires one unit of either ash or lye.
Since lye is produced from ash, it is extra work to use lye to produce potash, but lye gets the job done just the same if you wish. Either method requires one initial unit of wood, which is then turned into ash by burning logs at a wood furnace, and then lye can be optionally produced at an ashery. While making ash directly into potash takes less time and uses fewer workers, making ash into lye first has several advantages:
- It keeps more dwarves busy, potentially satisfying needs
- It provides extra experience (and associated attribute increases) to the workers
- Lye can be stockpiled in much less space (100 units per barrel, compared to only 10 bars of ash per bin)
- Lye can also be used to make soap
Potash is produced in bars with no quality level. These bars are stored in bar stockpiles, and are viewable in the stocks screen under "bars."
Uses[edit]
Potash can be used to fertilize a farm plot, increasing the stack size of harvested plants. Doing so can help cut down on the need for large farms, which may result in less labor overall.
Alternatively, potash can be further processed into pearlash at a kiln or magma kiln. This material is necessary if you wish to produce glass products of clear or crystal quality. Because potash is a wood-based product, elves will refuse to trade it.
Real world[edit]
Potash refers to a wide variety of potassium-bearing salts, first produced in roughly 500 CE. In modern times, they are used primarily in production of fertilizer, though they were once part of glass and soap production. While modern production methods have developed, this substance was once produced by soaking plant ash in a pot full of water, thus the name pot-ash, which in turn gives the name to the element potassium.
