Slip (ceramics)
Ancient Roman potteryPottery was produced in enormous quantities in ancient Rome, mostly for utilitarian purposes. It is found all over the former Roman Empire and beyond. Monte Testaccio is a huge waste mound in Rome made almost entirely of broken amphorae used for transporting and storing liquids and other products – in this case probably mostly Spanish olive oil, which was landed nearby, and was the main fuel for lighting, as well as its use in the kitchen and washing in the baths.Glossary of pottery termsThis is a list of pottery and ceramic terms. Definitions in Wiktionary are noted as "(W)".AAbsorbencyThe ability of a material to soak up water.AluminaA major component of the chemical composition of clays, clay bodies and most glazes.ArkLarge tank for the storage of slip. To prevent sedimentation it is gently agitated by slowly rotating blades.AtmosphereThe gaseous environment within the kiln during the firing process.
Barbotineis the French for ceramic slip, or a mixture of clay and water used for moulding or decorating pottery. In English the term is used for three different techniques of decorating pottery, though in all cases mainly for historical works. For clarity, these types are numbered here as A-C (which are not standard terms).
PotteryCraft of making objects from clayHand building a jarPottery is the process and the products of forming vessels and other objects with clay and other raw materials, which are fired at high temperatures to give them a hard and durable form. The place where a potter makes such wares is also called a pottery (plural potteries).Leather-hard
African red slip wareAfrican red slip ware, also African Red Slip or ARS, is a category of terra sigillata, or "fine" Ancient Roman pottery produced from the mid-1st century AD into the 7th century in the province of Africa Proconsularis, specifically that part roughly coinciding with the modern country of Tunisia and the Diocletianic provinces of Byzacena and Zeugitana. It is distinguished by a thick-orange red slip over a slightly granular fabric.
ClayClay is a type of fine-grained natural soil material containing clay minerals (hydrous aluminium phyllosilicates, e.g. kaolinite, Al2Si2O5(OH)4). Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour from small amounts of iron oxide. Clays develop plasticity when wet but can be hardened through firing. Clay is the longest-known ceramic raw material.
QuartzQuartz is a hard mineral composed of silica (silicon dioxide). Its atoms are linked in a continuous framework of SiO4 silicon–oxygen tetrahedra, with each oxygen atom being shared between two tetrahedra, giving an overall chemical formula of SiO2. Therefore, quartz is classified structurally as a framework silicate mineral and compositionally as an oxide mineral. Quartz is the second most common mineral or mineral group in Earth's lithosphere, comprising about 12% by mass.
MicaMicas () are a group of silicateminerals whose outstanding physical characteristic is that individual mica crystals can easily be split into fragile elastic plates. This characteristic is described as perfect basal cleavage. Mica is common in igneous and metamorphic rock and is occasionally found as small flakes in sedimentary rock.
Black-figure potteryBlack-figure pottery painting (also known as black-figure style or black-figure ceramic; Ancient Greek: , romanized: melanómorpha) is one of the styles of painting on antique Greek vases. It was especially common between the 7th and 5th centuries BC, although there are specimens dating in the 2nd century BC. Stylistically it can be distinguished from the preceding orientalizing period and the subsequent red-figure pottery style.
FeldsparFeldspar ( ; sometimes spelled felspar) is a group of rock-forming aluminium tectosilicate minerals, also containing other cations such as sodium, calcium, potassium, or barium. The most common members of the feldspar group are the plagioclase (sodium-calcium) feldspars and the alkali (potassium-sodium) feldspars. Feldspars make up about 60% of the Earth's crust and 41% of the Earth's continental crust by weight.
