Papier-mâché

Relief is a sculptural method in which the sculpted pieces remain attached to a solid background of the same material. The term relief is from the Latin verb relevare, to raise (lit. 'to lift back'). To create a sculpture in relief is to give the impression that the sculpted material has been raised above the background plane. When a relief is carved into a flat surface of stone (relief sculpture) or wood (relief carving), the field is actually lowered, leaving the unsculpted areas seeming higher. The approach requires chiselling away of the background, which can be time-intensive. On the other hand, a relief saves forming the rear of a subject, and is less fragile and more securely fixed than a sculpture in the round, especially one of a standing figure where the ankles are a potential weak point, particularly in stone. In other materials such as metal, clay, plaster stucco, ceramics or papier-mâché the form can be simply added to or raised up from the background. Monumental bronze reliefs are made by casting.

There are different degrees of relief depending on the degree of projection of the sculpted form from the field, for which the Italian and French terms are still sometimes used in English. The full range includes high relief (Italian alto-rilievo, French haut-relief), where more than 50% of the depth is shown and there may be undercut areas, mid-relief (Italian mezzo-rilievo), low relief (Italian basso-rilievo, French: bas-relief), and shallow-relief (Italian rilievo schiacciato), where the plane is only very slightly lower than the sculpted elements. There is also sunk relief, which was mainly restricted to Ancient Egypt (see below). However, the distinction between high relief and low relief is the clearest and most important, and these two are generally the only terms used to discuss most work.

The Mesha Stele, also known as the Moabite Stone, is a stele dated around 840 BCE containing a significant Canaanite inscription in the name of King Mesha of Moab (a kingdom located in modern Jordan). Mesha tells how Chemosh, the god of Moab, had been angry with his people and had allowed them to be subjugated to the Kingdom of Israel, but at length, Chemosh returned and assisted Mesha to throw off the yoke of Israel and restore the lands of Moab. Mesha also describes his many building projects. It is written in a variant of the Phoenician alphabet, closely related to the Paleo-Hebrew script.

The stone was discovered intact by Frederick Augustus Klein, an Anglican missionary, at the site of ancient Dibon (now Dhiban, Jordan), in August 1868. A "squeeze" (a papier-mâché impression) had been obtained by a local Arab on behalf of Charles Simon Clermont-Ganneau, an archaeologist based in the French consulate in Jerusalem. The next year, the stele was smashed into several fragments by the Bani Hamida tribe, seen as an act of defiance against the Ottoman authorities who had pressured the Bedouins to hand over the stele so that it could be given to Germany. Clermont-Ganneau later managed to acquire the fragments and piece them together thanks to the impression made before the stele's destruction.

Methyl cellulose (or methylcellulose) is a compound derived from cellulose. It is sold under a variety of trade names and is used as a thickener and emulsifier in various food and cosmetic products, and also as a bulk-forming laxative. Like cellulose, it is not digestible, non-toxic, and not an allergen. In addition to culinary uses, it is used in arts and crafts such as papier-mâché and is often the main ingredient of wallpaper paste.
