also spelled  Mastich,  

      aromatic resin, obtained as a soft exudation from incisions in mastic trees. It is used chiefly to make pale varnishes for protecting metals and paintings. When dispersed in bodied (thickened by heating) linseed oil, mastic is known as megilp and is used as a colour vehicle. Mastic is also used as an adhesive in dental work.

      The mastic, or lentisc, tree, Pistacia lentiscus, an evergreen shrub of the sumac family (Anacardiaceae), is indigenous to the Mediterranean coast region from Syria to Spain, and particularly the Greek archipelago, but grows also in Portugal, Morocco, and the Canary Islands. Since about AD 50, production of the resin has been confined almost exclusively to the Greek island of Khíos in the Aegean Sea.

      The resin is contained in the bark and not in the wood, and in order to collect it numerous vertical incisions are made, during June, July, and August, in the stem and chief branches. The resin speedily exudes and hardens into oval tears, which are collected every 15 days. The collection is repeated several times between June and September. Mastic is usually marketed in the form of roundish tears about the size of peas. These are transparent, with a glassy fracture, of a pale yellow or faint greenish tinge, which darkens slowly.

      Other trees yield resins that are referred to as mastic. In Algeria, Pistacia atlantica yields a solid resin. Cape mastic is the produce of Euryops multifidus, the resin bush, or hairpuis bosch of the Boers—a plant of the family Compositae. Dammar resin is sometimes sold under the name of mastic. The West Indian mastic tree is Bursera gummifera, and the Peruvian mastic, or California pepper tree, is Schinus molle. The name mastic tree is also applied to a timber tree, Sideroxylon mastichodendron, family Sapotaceae, which grows in the West Indies and on the coast of Florida.

      The term mastic is also used for various pasty materials used as protective coatings (for example, in thermal insulation and in waterproofing) and as cements (for example, in setting tile or wall panels).
