Apothecary historical name for a medical professional now called a pharmacist

Apothecary is one term for a medical professional who formulates and dispenses materia medica to physicians, surgeons, and patients. The modern pharmacist has taken over this role. In some languages and regions, the word "apothecary" is still used to refer to a retail pharmacy or a pharmacist who owns one. Apothecaries' investigation of herbal and chemical ingredients was a precursor to the modern sciences of chemistry and pharmacology.

Magnesium oxide chemical compound

Magnesium oxide (MgO), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide). It has an empirical formula of MgO and consists of a lattice of Mg2+ ions and O2− ions held together by ionic bonding. Magnesium hydroxide forms in the presence of water (MgO + H2O → Mg(OH)2), but it can be reversed by heating it to separate moisture.

Prussian blue is a dark blue pigment produced by oxidation of ferrous ferrocyanide salts. It has the idealized chemical formula Fe
. Another name for the color is Berlin blue or, in painting, Parisian or Paris blue. Turnbull's blue is the same substance, but is made from different reagents, and its slightly different color stems from different impurities.
