An 1836 lithograph of tortilla production in rural Mexico Bowl of hominy (nixtamalized corn kernels). Nixtamalization (/ ˌ n ɪ ʃ t ə m ə l ɪ ˈ z eɪ ʃ ən / nish-tə-mə-lih-ZAY-shən) is a process for the preparation of maize, or other grain, in which the grain is soaked and cooked in an alkaline solution, usually limewater (but sometimes aqueous alkali metal carbonates), [1] washed ...
Calcium oxide (formula: Ca O), commonly known as quicklime or burnt lime, is a widely used chemical compound. It is a white, caustic , alkaline , crystalline solid at room temperature . The broadly used term lime connotes calcium-containing inorganic compounds , in which carbonates , oxides , and hydroxides of calcium, silicon , magnesium ...
The term "calcium ammonium nitrate" is applied to multiple different, but closely related formulations. One variety of calcium ammonium nitrate is made by adding powdered limestone to ammonium nitrate; [1] [2] another, fully water-soluble version, is a mixture of calcium nitrate and ammonium nitrate, which crystallizes as a hydrated double salt: [3] 5Ca(NO 3) 2 •NH 4 NO 3 •10H 2 O.
Calcium hydroxide (traditionally called slaked lime) is an inorganic compound with the chemical formula Ca 2. It is a colorless crystal or white powder and is produced when quicklime (calcium oxide) is mixed with water. Annually, approximately 125 million tons of calcium hydroxide are produced worldwide. [8]
Coriander (/ ˌ k ɒr i ˈ æ n d ər, ˈ k ɒr i æ n d ər /), [1] whose leaves are known as cilantro (/ s ɪ ˈ l æ n t r oʊ,-ˈ l ɑː n-/) [1]: 90 in the U.S., is an annual herb (Coriandrum sativum) in the family Apiaceae. Most people perceive the leaves as having a fresh, slightly citrus taste.

The hot chocolate effect is a phenomenon of wave mechanics in which the pitch heard from tapping a cup of hot liquid rises after the addition of a soluble powder. [ 1 ] [ 2 ] The effect is thought to happen because upon initial stirring, entrained gas bubbles reduce the speed of sound in the liquid, lowering the frequency.
The pozzolanic reaction converts a silica-rich precursor with no cementing properties, to a calcium silicate, with good cementing properties. In chemical terms, the pozzolanic reaction occurs between calcium hydroxide , also known as portlandite (Ca(OH) 2 ), and silicic acid (written as H 4 SiO 4 , or Si(OH) 4 , in the geochemical notation):
