Mastic (plant resin) in the context of "Resin"

Chios (/ˈkaɪ.ɒs, ˈkaɪ.oʊs, ˈkiː-/; Greek: Χίος, romanized: Chíos [ˈçi.os] , traditionally known as Scio in English) is the fifth largest Greek island, situated in the northern Aegean Sea, and the tenth largest island in the Mediterranean Sea. The island is separated from Turkey by the Chios Strait. Chios is notable for its exports of mastic gum and its nickname is "the Mastic Island". Tourist attractions include its medieval villages and the 11th-century monastery of Nea Moni, a UNESCO World Heritage Site.

Administratively, the island forms a separate municipality within the Chios regional unit, which is part of the North Aegean region. The principal town of the island and seat of the municipality is Chios. Locals refer to Chios town as Chora (Χώρα literally means land or country, but usually refers to the capital or a settlement at the highest point of a Greek island).

The Last Supper (Italian: Il Cenacolo [il tʃeˈnaːkolo] or L'Ultima Cena [ˈlultima ˈtʃeːna]) is a mural painting by the Italian High Renaissance artist Leonardo da Vinci, dated to c. 1495–1498, housed in the refectory of the Convent of Santa Maria delle Grazie in Milan, Italy. The painting represents the scene of the Last Supper of Jesus with the Twelve Apostles, as it is told in the Gospel of John – specifically the moment after Jesus announces that one of his apostles will betray him. Its handling of space, mastery of perspective, treatment of motion and complex display of human emotion has made it one of the Western world's most recognizable paintings and among Leonardo's most celebrated works. Some commentators consider it pivotal in inaugurating the transition into what is now termed the High Renaissance.

The work was commissioned as part of a plan of renovations to the church and its convent buildings by Leonardo's patron Ludovico Sforza, Duke of Milan. In order to permit his inconsistent painting schedule and frequent revisions, it is painted with materials that allowed for regular alterations: tempera on gesso, pitch, and mastic. Due to the methods used, a variety of environmental factors, and intentional damage, little of the original painting remains today despite numerous restoration attempts, the last being completed in 1999. The Last Supper is Leonardo's largest work, aside from the Sala delle Asse.

Pistacia lentiscus (also lentisk or mastic) is a dioecious evergreen shrub or small tree of the genus Pistacia native to the Mediterranean Basin. It grows up to 4 m (13 ft) tall and is cultivated for its aromatic resin, mainly on the Greek island of Chios, around the Turkish town of Çeşme and northern parts of Iraq.

A release liner or release paper, also called a backing liner, is a paper or plastic-based film sheet (usually applied during the manufacturing process) used to prevent a sticky surface from prematurely adhering. It is coated on one or both sides with a release agent, which provides a release effect against any type of a sticky material such as an adhesive or a mastic. Release liners are available in different colors, with or without printing under the low surface energy coating or on the backside of the liner. Release is separation of the liner from a sticky material; liner is the carrier for the release agent.
