Salt usage questions
Can anyone please explain -- part says "the storage tank's interior was scattered with a salty compound that would form a surface on top of the water" -- another part says "To prevent form rotting, salt lick was added to the water from the top of the tank. Due to the stagnation of water, the salt lick was not dissolve in the whole water and over time, a dense saltwater was form at the bottom of the tank about one meter."


 * How does salt both float and sink, or what information has been left out here? Perhaps something else was floating on the surface?


 * Was "form rotting" (the rotting of a form) or "from rotting" (the rotting of other materials in the water) the intended meaning? — Preceding unsigned comment added by 24.16.88.201 (talk) 20:18, 5 September 2020 (UTC)

Bottom filled with metals
Can anyone please explain "The bottom of the storage tanks were often filled with metals for various structural reasons."


 * Was "covered" or "filled" intended? "filled" implies a much greater volume of metal than a (perhaps) 2 to 6mm layer.


 * What metals were used?


 * Would this be a layer of (perhaps) lead to provide a leak-proof impermeable bottom? The article text:  "The 18th century monarch Agha Muhammad Khan, is said to have extracted the metals from the bottom of the Ganjali Khan public baths to make bullets for a battle.[1]" would be consistent with lead usage.

 * If lead or another toxic metal was was used, what effect might this have on public health?
