From Wikipedia, the free encyclopedia


Stoneware a vitreous or semivitreous ceramic ware of fine texture, made primarily from nonrefactory fire clay. [1] Its maturation temperature ranges from about 1200°C to 1315 °C. In essence, it is man-made stone. One widely recognized definition is from the Combined Nomenclature of the European Communities which states, "Stoneware, which, though dense, impermeable and hard enough to resist scratching by a steel point, differs from porcelain because it is more opaque, and normally only partially vitrified. It may be vitreous or semi-vitreous. It is usually coloured grey or brownish because of impurities in the clay used for its manufacture, and is normally glazed".[2]

In contrast, earthenware is fired at lower temperatures and is not impervious to liquids. Porcelain, which some consider to be a type of stoneware, is distinguished as being whiter than stoneware and always vitreous. Kaolin, or China Clay, has a lower content of impurities than many other clays. It is also fired to a vitreous state, transforming the constituent silica into glass. Some porcelain bodies are translucent after firing. Firing a piece of pottery to too high a temperature will result in warping or melting. Vitreous clay bodies can be made at different temperatures ranges, but they are typically fired in the stoneware/porcelain range. Fired stoneware absorbs up to 5% water, porcelain 0%, and earthenware up to 10%. Earthenware, when moist, is typically not freeze resistant.

Clay refers to group of minerals that generally exhibit plasticity when mixed with water, and which chemically primarily consist of alumina and silica. Potters refer to combinations of clays mixed with other materials as clay bodies. Different kinds of clay bodies are created by mixing additives, such as feldspar, grog, quartz, flint, many other minerals are used and these can include spodumene, wollastonite to modify clays. Clay bodies can thereby be formulated to fire at a range of temperatures. Darker clays often contain iron and other metal oxide impurities. The clay used for porcelain and white stoneware clay bodies contain very little of these impurities.

Glaze may be applied to stoneware pottery before a second firing at a different temperature, or a glaze may be applied before a single, raw firing. Salt-glazed stoneware became the dominant houseware of nineteenth century America.

Stone-ware tiles

These are some of the artificial stone tiles we can offer. They are as beautiful and warm as natural stones but with more advantages like better resistance, so it is possible to have tiles with a reduced thickness (3/8") also for big tiles (24"x24"). This results in an easier installation and less expensive transport.

The stone-ware tiles have also a very limited adsorption so they don't require any treatment or special maintenance after installation. Stone-ware have matching mosaics, inserts and borders decorations ideal to create decorative patterns on floors or walls.

Stone-ware tiles are available in satin finish (smooth and matt surface ) and structured finish (rough surface) which has the best no-slippery features, required for outdoor use (R 12 value) or around swimming pools.

stoneware

Very hard, opaque, water resistant pottery made of non-porous (non-absorbent) clay with feldspar and a high silica content. it is fired at high temperatures (1.200-1.280'C /2.192-2.336'F) to the point of vitrification, producing a glasslike, non-porous material that is between porcelain and earthenware in character.

Stone ware usually fires to shades of grey or buff, thoug some red stonewares do exist, Glazing decorates and gives the survaces a smooth finish. The earliest examples are chinese, from the 10th to 3rd centuries BC.

From the 9th century AD stone ware was made in northern Europe, in Britain from the late 17th century.

TIPS ON CARING FOR YOUR TERRACOTTA POTTERY.

Bali, Lombok and Javanese pottery is low fired, Its maximum firing temperature is about 650.C – 750.C which makes it porous, even when fired to maturity. This pottery is fragile, but with careful handling and maintenance it will last for many many years.

Large terracotta pots are traditionally used as water storage jars but are more commonly used in modern times for decorative purposes. The colors and sheen of the pottery will last longer if not exposed to damp conditions. If used as plant pot without an inner plastic container, root growth pressure will eventually crack the pot. Damp conditions are conducive to mould which will spoil the surface of the pot and obliterate any color, firing marks or decoration.
In destination countries terracotta pots have been stored outside in temperatures of minus 14 degrees Celsius without breakage, Unless treated with a sealer moisture in the pottery will, as ice, expand and break the pot. We recommend the largest terracotta pots be kept in dry conditions where possible.


Bali, Lombok and Javanese terracotta tableware should be used as decoration. Normal washing by hand with detergent is recommended, the pottery should then be left to air dry.

The glazed pottery ( Teapots / cups and saucers etc. are high fired with a lead free process and are most suitable for private and commercial environments, the same ceramics are used here in large resort hotels.. .

Working With Clay : Exploring Pottery & Ceramics

See also :Polymer Clay

Pottery is a clay sculpting art form that dates back to ancient times. Whether hand-built or wheel-thrown, this art medium is still popular today.
Traditional pottery is made by forming bowls, cups, and other vessels from stoneware, terra cotta, or other clay by hand or on a wheel. The clay is then allowed to air dry before being fired in a kiln. After the firing, the clay is glazed (painted), and fired for a second time before ready to use.
The following resources point you to leading online pottery and ceramics publications and Web sites that are informative as well as instructional to those seeking to explore this enduring craft.

Ceramic Wall Tile

Ceramic tile is nothing new. It has actually been in use for centuries and is one of the more beautiful additions a person can make to their home. Ceramic tiles are available in many colors, patters and even textures if you are looking for something truly unique. Today''s ceramic tiles can be made to look identical in every way to more expensive products like stone and slate. Ceramic tile is usually glazed and looks great in the kitchen or bathroom. A ceramic tile basically starts out as two simple elements, water and clay. Different types of clay are first ground into a fine powdered and then mixed together. The powdered is then compressed until it forms the body of the tile. Moisture content is reduced through a drying process and then the glaze is applied. The tile is then fired in a kiln at around 2000 degrees Fahrenheit, which fuses the glaze to the surface. During the firing process the glaze takes on a glass like texture. In addition to ceramic, porcelain can be used to make a very dense, moisture resistant and durable tile. Porcelain unlike many other types of tile can be used as flooring in heavy traffic areas for many years without showing signs of wear. One decorative way that ceramic tile can be used is with wall tiles. Different from the tiles used for flooring, wall tiles have a glazed surface that can become very slippery when wet, which is why it isn''t used for floors. Wall tiles are also useful when making tile countertops as well since they are fairly easy to keep clean. Since the tiles are created for flooring they are less durable then regular tile. Available in a wide range of colors and styles, your wall tile can really serve to bring several elements of a room together. Often times the fixtures in a bathroom and the floor don''t seem to work together, but with the addition of wall tile, the two seem to blend in harmony.
