Pellets of soda lye (sodium hydroxide) Pellets of potash lye (potassium hydroxide)Lye is a hydroxide, either sodium hydroxide or potassium hydroxide.The word lye most accurately refers to sodium hydroxide (NaOH), [citation needed] but historically has been conflated to include other alkali materials, most notably potassium hydroxide (KOH).
The lye and potash stages were commonly performed on site by the settlers themselves, and the asheries only performed the final step and most difficult step of converting the black salts to pearlash. The product was often shipped to Great Britain where it was used in the production of glass and ceramic wares.
However, lye is not the only way to produce the needed result: a baking soda or washing soda solution, which is easier to handle and safer to use, will provide a similar product but will not provide as strong a reaction, so the effect will be less pronounced. Lye is the strongest agent, followed by washing soda, and then baking soda.
To make hominy, field corn (maize) grain is dried, and then it is treated by soaking and cooking the mature (hard) grain in a dilute solution of lye (potassium hydroxide) (which can be produced from water and wood ash) or slaked lime (calcium hydroxide from limestone). The maize is then washed thoroughly to remove the bitter flavor of the lye ...
The old method of making potassium carbonate (K 2 CO 3) was by collecting or producing wood ash (the occupation of ash burners), leaching the ashes, and then evaporating the resulting solution in large iron pots, which left a white residue denominated "pot ash". [9] Approximately 10% by weight of common wood ash can be recovered as potash.
Lye water is an essential ingredient in the crust of the traditional baked Chinese moon cakes. Most yellow coloured Chinese noodles are made with lye water but are commonly mistaken for containing egg. One variety of zongzi uses lye water to impart a sweet flavor. Sodium hydroxide causes gelling of egg whites in the production of century eggs.
Conk hairstyle. The conk was a hairstyle popular among African-American men from the 1920s up to the early-to-mid 1960s. [1] This hairstyle called for a man with naturally "kinky" hair to have it chemically straightened using a relaxer called congolene, an initially homemade hair straightener gel made from the extremely corrosive chemical lye which was often mixed with eggs and potatoes.
The saturated lutefisk is then soaked in an unchanged solution of cold water and lye for an additional two days. The fish swells during this soaking, and its protein content decreases by more than 50 percent, producing a jelly-like consistency. When this treatment is finished, the fish is saturated with lye and inedible, with a pH of 11–12.
