Qadad
''Qadad'' ( ''qaḍāḍ'') or ''qudad'' is a waterproof plaster surface, made of a lime plaster treated with slaked lime and oils and fats. The technique is over a thousand years old, with the remains of this early plaster still seen on the standing sluices of the ancient Marib Dam. Volcanic ash, pumice, scoria ( ar, شاش), in the Yemeni dialect, or other crushed volcanic aggregate are often used as pozzolanic agents, reminiscent of ancient Roman lime plaster which incorporated pozzolanic volcanic ash. Due to the slowness of some of the chemical reactions, ''qadad'' mortar can take over a hundred days to prepare, from quarrying of raw materials to the beginning of application to the building. It can also take over a year to set fully. In 2004, a documentary film ''Qudad, Re-inventing a Tradition'' was made by the filmmaker Caterina Borelli. It documents the restoration of the Amiriya Complex, which was awarded the Aga Khan Award for Architecture in 2007. Old method of p ...

Lime Plaster
Lime plaster is a type of plaster composed of sand, water, and lime, usually non-hydraulic hydrated lime (also known as slaked lime, high calcium lime or air lime). Ancient lime plaster often contained horse hair for reinforcement and pozzolan additives to reduce the working time. Traditional non-hydraulic hydrated lime only sets through carbonatation when the plaster is kept moist and access of CO2 from the air is possible. It will not set when submersed in water. When a very thick layer or several layers are applied, the lime can remain soft for weeks. The curing time of lime plaster can be shortened by using (natural) hydraulic lime or adding pozzolan additives, transforming it into artificially hydraulic lime. In ancient times, Roman lime plaster incorporated pozzolanic volcanic ash; in modern times, fly ash is preferred. Non-hydraulic lime plaster can also be made to set faster by adding gypsum. Lime production for use in plastering home-made cisterns (in making them ...

Pozzolan
Pozzolans are a broad class of Silicon_dioxide, siliceous and aluminium oxide, aluminous materials which, in themselves, possess little or no cementitious value but which will, in finely divided form and in the presence of water, react chemically with calcium hydroxide (Ca(OH)2) at ordinary temperature to form compounds possessing cementitious properties. The quantification of the capacity of a pozzolan to react with calcium hydroxide and water is given by measuring its pozzolanic activity. ''Pozzolana'' are naturally occurring pozzolans of volcanic origin. History Mixtures of Calcination, calcined lime and finely ground, active aluminosilicate materials were pioneered and developed as inorganic binders in the Ancient world. Architectural remains of the Minoan civilization on Crete have shown evidence of the combined use of Calcium hydroxide, slaked lime and additions of finely ground potsherds for waterproof Cement render, renderings in baths, cisterns and aqueducts.

Great Mosque Of Sana'a
The Great Mosque of Sana'a (, ) is an ancient mosque in Sana'a, Yemen, and one of the oldest mosques in the world. The mosque is said to have been founded in the early Islamic period, suggested to be in 633. While the precise date of construction is unknown, the earliest recorded renovations occurred under Caliph al-Alid I in the early 8th century, implying a possible earlier date of construction. The mosque was reportedly built in part from spolia from the Himyarite-era Ghumdan Palace and from the Axumite Christian Church of al-Qalis that formerly occupied the site. The Great Mosque is the largest and most notable of over one hundred mosques in the Old City of Sana’a.Smith, G.R., “Ṣanʿāʾ”, in: Encyclopaedia of Islam, Second Edition, Edited by: P. Bearman, Th.

Yeseria
Stucco decoration in Islamic architecture refers to carved or molded stucco and plaster. The terms "stucco" and "plaster" are used almost interchangeably in this context to denote most types of stucco or plaster decoration with slightly varying compositions. This decoration was mainly used to cover walls and surfaces and the main motifs were those predominant in Islamic art: geometric, arabesque (or vegetal), and calligraphic, as well as three-dimensional ''muqarnas''. Plaster of gypsum composition was extremely important in Islamic architectural decoration as the relatively dry climate throughout much of the Islamic world made it easy to use this cheap and versatile material in a variety of spaces. Stucco decoration was already used in ancient times in the region of Iran and the Greco-Roman Mediterranean. In Islamic architecture, stucco decoration appeared during the Umayyad period (late 7th–8th centuries) and underwent further innovations and generalization during the 9th c ...

Suet
Suet is the raw, hard fat of beef, lamb or mutton found around the loins and kidneys. Suet has a melting point of between 45 °C and 50 °C (113 °F and 122 °F) and congelation between 37 °C and 40 °C (98.6 °F and 104 °F). Its high smoke point makes it ideal for deep frying and pastry production. The primary use of suet is to make tallow, although it is also used as an ingredient in cooking, especially in traditional baked puddings, such as British Christmas pudding. Suet is made into tallow in a process called rendering, which involves melting fats and extended simmering, followed by straining, then cooling. The entire process is then usually repeated to refine the product. Etymology The word ''suet'' is derived from Anglo-Norman , from Old French , from Latin ("tallow", "grease", "hard animal fat"). ''Sebum'' is from the Proto-Indo-European root *''seyb''- ("pour out, trickle"), so it shares a root with sap and soap. Trade ...

Lime Mortar
Lime mortar or torching is composed of lime and an aggregate such as sand, mixed with water. The ancient Egyptians were the first to use lime mortars, which they used to plaster their temples. In addition, the Egyptians also incorporated various limes into their religious temples as well as their homes. Indian traditional structures built with lime mortar, which are more than 4,000 years old like Mohenjo-daro is still a heritage monument of Indus valley civilization in Pakistan. It is one of the oldest known types of mortar also used in ancient Rome and Greece, when it largely replaced the clay and gypsum mortars common to ancient Egyptian construction. With the introduction of Portland cement during the 19th century, the use of lime mortar in new constructions gradually declined. This was largely due to the ease of use of Portland cement, its quick setting, and high compressive strength. However, the soft and porous properties of lime mortar provide certain advantages when work ...

Taiz ( ar, تَعِزّ, Taʿizz) is a city in southwestern Yemen. It is located in the Yemeni Highlands, near the port city of Mocha, Yemen, Mocha on the Red Sea, at an elevation of about above sea level. It is the capital of Taiz Governorate. With a population of over 600,000 in 2005, it is the largest city in Yemen in terms of population ahead of the capital Sana'a and the southern port city of Aden. Due to the Taiz campaign (2015–present), ongoing campaign as part of Yemeni Civil War (2015–present), Yemen's civil war, Taiz is a battleground and a war zone. Once known as the "cultural capital of Yemen", the war has bestowed a new title, "city of snipers". History The 14th century traveller Ibn Battuta visited Taiz: We went on ... to the town of Taʻizz, the capital of the king of Yemen, and one of the finest and largest towns in that country.
