One of several forms of aluminium potassium sulphate which is used in treating leather, in paper-making, and as a mordant to fix dyes in the textile industry Supplies of alum came from Rome until these were stopped in the 17th century by the Pope – because of the dispute with Henry VIII A local industry then sprang up at Ravenscar on the east coast of Yorkshire There was a short-lived alum export industry from Whitby in the 18th century; An astrigent crystalline substance used in rosin sizing to hold paper fibers together; responsible for introducing acid into the paper; aluminum sulfate, commonly called Floc Used to help clarify water Causes small particles to join together so they can be trapped in filter Alum lowers the pH of the water; a double sulphate of aluminum and potassium that is used as an astringent (among other things) a white crystalline double sulfate of aluminum: the potassium double sulfate of aluminum a white crystalline double sulfate of aluminum: the ammonium double sulfate of aluminum; It has twenty-four molecules of water of crystallization; an alkali metal or of aluminium; A double sulphate formed of aluminium and some other element esp; To steep in, or otherwise impregnate with, a solution of alum; to treat with alum; a former student of a school, college etc (alumen). Inorganic compound, any of a class of hydrated double salts, usually consisting of aluminum sulfate, water of hydration (an essential part of the crystal makeup), and the sulfate of another element. The most important alums are those of potassium sulfate (potassium alum, or potash alum, K2SO4Al2(SO4)324H2O), ammonium sulfate, and sodium sulfate. Alums occur naturally in various minerals and can be prepared and purified by crystallization from their solutions. Most are white crystals with an astringent, acid taste. They are used as paper-sizing agents, flocculating agents in water treatment, mordants in dyeing, and in pickles, baking powder, fire extinguishers, and medicines; A double sulphate formed of aluminum and some other element (especially an alkali metal) or of ammonium; {i} double sulfate (Chemistry); alumen
