Materials that were used to create an object (main ones).

aluminium (metals): Light metal with low hardness, highly resistant to corrosion and mainly it is used mixed with other elements such as magnesium, silicon or titanium alloy to increase its ability to tensile strength and hardness. Its main uses are in carpentry, as well as sometimes in the manufacture of decorative elements.
asphalt (stone): Sticky, black and highly viscous liquid or semi-solid that is present in most crude petroleum and used to build pavements, streets and roads.
azulejo (clay): Thin ceramic piece, commonly square-shaped with one brilliant and water-proof coloured band. Tile is generally used as a covering piece of walls and surfaces as well as an isolated decorative element.
brick (clay): Ceramic block material, made by clay cooked at high temperatures. The block commonly has a geometrical shape, orange-brown colour and it is used in constructions and masonry.
bronze (metals): Metal alloy made by copper and tin. Use to create ships, hammers, mallets, wrenches and other durable tools. Currently mainly associated as a valuable and decorative material.
cement (stone): Binder formed by clay and different kind of stones. When it contacts with water and dries it becomes hard almost immediately. It is widely used in construction and civil engineering.
ceramics (clay): Pieces made of porcelain, clay or other baked materials used in architecture as decorative elements in walls or other surfaces. Frequently these ceramic pieces can be covered by varnish and then they are called 'azulejo'.
cladding (): An external, covering material, that serves as decorative and protective layer. Cladding can be made of various, different materials formed as a elevation panels eg. titanium cladding, zinc cladding, wooden cladding, stone panels, copper cladding, fibre cement panels etc.
cobblestone (stone): Stone blocks used in the construction of pavements in streets. They are made by granite usually due its resistance and hardness.
concrete (stone): Construction material formed by cement and other materials, such as crushed stones (granite and others), sand and water. It solidifies and its hardness is due a chemical process named 'hydration'. This process gives to concrete a lot of resistance to compression efforts. It is commonly used in construction, pavements, civil engineering and other architectural structures. Sometimes concrete is mixed with steel sticks and used as a complex to optimize structure in traction and bending efforts.
copper (metals): Transition metal reddish orange, whose main characteristic is to possess the greatest capacity for electrical conductivity. It is part of numerous alloys, although primarily used in the manufacture of electric cables, electronic components and water pipes. It is also used in sculpture or decorative architectural elements.
floor tile (stone): Manufactured piece made by different materials such as ceramic or stone. Floor tiles are generally used for covering floors, pavements and even walls. They can be used as a functional element or as a decorative one.
glass (sand): Amorphous and non-crystalline inorganic material, formed by fusion at 1500ºC degrees by silica, and other ingredients such as sodium carbonate. It is used basically to make windows or bottles and other decorative elements. Its main characteristic is its transparency.
gold (metals): a dense, soft, shiny, malleable and ductile metal and is a chemical element with the symbol Au and atomic number 79; Gold has been a valuable and highly sought-after precious metal for coinage, jewelry, and other arts since long before the beginning of recorded history.
granite (stone): Igneous stone formed by quartz, feldspar and biotite. It is commonly used in pavements, monuments and decorative elements of constructions.
grass (nature): Herbaceous plants with narrow leaves that grow from the base and are widely used in parks and gardens as well as some stadiums and sports fields.
gypsum (stone): Mineral composed of hydrated calcium sulfate used in construction. Gypsum is a building material white and easy to shape while wet. Once dry, the plaster becomes rigid and has therefore been used since ancient times. The hardened plaster is sensitive to water thus is normally used indoors.
iron (metals): Chemical element with the symbol Fe, it forms 5% of the whole materials on Earth. It is a metal in the first transition series. It has magnetic properties and is very heavy and hard.
limestone (stone): a sedimentary rock composed largely of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3); many limestones are composed from skeletal fragments of marine organisms such as coral or foraminifera
marble (stone): Metamorphic stone formed by calcite dolomite. Its main characteristic is its colour, white with silver veins. It is used in construction of sculptures, monuments and decorative elements.
other (): uncategorized
paper (organic): Material made from mixing vegetable pastes, from different plants. Its main composition is cellulose, a polymer of glucose units.
plastics (plastic): Synthetic materials obtained by polymerization phenomena or semi-natural multiplication of carbon atoms in the long molecular chains of organic compounds derived from petroleum and other natural substances.
sand (sand): It is a granular material composed of divided rock and mineral particles. Its texture depends on the diameter of the particle. It is usually found in beaches and it is used also as a component of other construction materials.
shrub (nature): Woody plant which the main difference with tree is that on this one branches directly grown on its base, directly from the land, without forming a common trunk. Like trees, shrub is used in parks and gardens, as well as avenues and tree-lined streets as a landscape element.
slate (stone): fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism. Slate is frequently grey in color, especially when seen, en masse, covering roofs.
snow (nature): is a form of precipitation within the Earth's atmosphere in the form of crystalline water ice, consisting of a multitude of snowflakes that fall from clouds.
soapstone (stone): Soapstone (also known as steatite or soaprock) is a metamorphic rock, a talc-schist.
steel (metals): Alloy formed by iron and carbon. It is the most important alloy in constructions, specially in beams, metallic profiles and bars for reinforced concrete. Usually other elements are added to steel to give more hardness and avoid corrosion due to presence of iron.
stone (stone): In geology, rock or stone is a naturally occurring solid aggregate of minerals. There are three classic types of stones, metamorphic, igneous and sedimentary.
tile (clay): Clay piece which is used to made roofs to canalize water from rain or snow.
titanium clad (metals): A cladding material from titanium. Titanium is a material which have high strength-to-weight ratio. It is strong, light and also corrosion-resistant.
travertine (stone): Travertine is a form of limestone deposited by mineral springs, especially hot springs. Travertine often has a fibrous or concentric appearance and exists in white, tan, and cream-colored varieties. It is formed by a process of rapid precipitation of calcium carbonate, often at the mouth of a hot spring or in a limestone cave. In the latter, it can form stalactites, stalagmites, and other speleothems. It is frequently used in Italy and elsewhere as a building material.
tree (nature): Woody plant which produces branches at specific high from land level. It is commonly used in parks and gardens as well as avenues and tree-lined streets as a landscape element.
water (nature): Chemical substance formed by oxygen and hydrogen atoms. Its general formula is H20. It is essential in vital processes. It can be found in rivers or lakes in sweet form or in oceans and seas in salty form.
wood (organic): Plant material obtained by trunk of trees and shrubs. It has been used since antiquity in construction, as well as good insulation structure as the parquet floor. It is also used in the manufacture of furniture.
zinc (metals): Pure zinc was used for roofing where it replaced more expensive copper and lead in roofing. Pure zinc is subject to creep at ordinary temperatures. Zinc was also cast for sculptures and decorative elements. Decorative architectural elements were frequently cast in zinc, since it molded readily, was inexpensive compared to stone, and could be painted to imitate more expensive metals.
