laccicacid

Chem.: An acid said to have been separated from stick-lac by Dr. John. It is a yellow crystalline powder, soluble in water and alcohol, and forms deliquescent soluble salts with potash, soda, and lime; but insoluble salts with the oxides of mercury and lead. lăc-çine, s. [Eng. lac (1); -ine.] A substance formerly thought to be obtained from lac. lāçe, *laas, *las, s. [O. Fr. las, laqs = a snare, From Lat. laqueus.] *1. A snare, a gin. Morals , p. 973.) (P. Holland: Plutarch; 2. A string; a cord used to bind or festen, especially by interweaving; as a stay-lace, a boot-lace, . 3. A kind of network of threads of flax, cotton, gold or silver wire, or other suitable material, forming a fabric of transparent texture. Its origin is not known, but it appears to have been used by the ladies of ancient Greece and Rome. It was early used in Northern Italy, and is said to have been introduced into France by Mary de Medicis. In 1483 its importation into England was prohibited. Point lace was embroidered with the needle. Bone lace (Charles I.) was a kind of thread lace, and received its name from the bobbin being made of bone. About 1768, a stocking-weaver of North amp ton produced a machine for making lace; it was called the pin-frame, and is still employed in France for making the lace called tulle. In lace-weaving, the threads of the weft are twisted round those of the warp. The manner of twisting determines the character of the net and its name, as whip-net, mail-net, pattern-net, drop-net, spider-net, balloon net, Paris-net, bobbin-net. The following is a list of the cla ified laces: (1) Pillow-lace, the article or fabric being wholly made by hand (known as Valenciennes, Mechlin, Honiton, Bucking ham); or Guipure, made by the crotchet-needle; and silk lace, called blonde when white, and Chantilly, Puy, Grammont, and black Bucking hams hire, when black.
