O. C. Stephens

Oswold Counsell Stephens was a key figure in New Zealand's studio pottery movement. Born in Dunedin in 1896, he studied at various schools before receiving a gold medal for top student at Canterbury Agricultural College. Stephens went on to graduate from the University of Otago with first-class honours in organic chemistry in 1923.

His interest in the heat treatment of clays led to a job as a technical chemist at New Zealand Insulators Limited in Temuka. After losing his job during the depression, he built a studio and laboratory in his backyard and was appointed science master at King Edward Technical College in Dunedin in 1933, where he taught until 1961.

Stephens established Handcraft Pottery, a small semi-commercial workshop behind his home in Clyde Street, Dunedin. His production mostly used slip-cast techniques, but he later imported an electric kiln and built a larger kiln to fire both earthenware and stoneware. Stephens was drawn to the simple shapes of the Ming and Qing dynasties and their distinctive glazes, which he emulated.

He held several one-man shows by the 1940s and produced a set of six urns for Government House in 1948. Stephens was a founder and life member of the Otago Potters’ Group and the New Zealand Society of Potters. He organised the first exhibition of New Zealand potters in 1957 and exhibited regularly with the Otago Art Society. His work is held in several museums and galleries, including the Dunedin Public Art Gallery, Otago Museum, and New Zealand House in London.

Oak

Oak

Native to Europe and England, oak has been used for joinery, furniture and building since the beginning of the medieval civilisation. It is a pale yellow in colour when freshly cut and darkens with age to a mid brown colour.

Oak as a furniture timber was superceded by walnut in the 17th century, and in the 18th century by mahogany,

Semi-fossilised bog oak is black in colour, and is found in peat bogs where the trees have fallen and been preserved from decay by the bog. It is used for jewellery and small carved trinkets.

Pollard oak is taken from an oak that has been regularly pollarded, that is the upper branches have been removed at the top of the trunk, result that new branches would appear, and over time the top would become ball-like. . When harvested and sawn, the timber displays a continuous surface of knotty circles. The timber was scarce and expensive and was used in more expensive pieces of furniture in the Regency and Victorian periods.

Obelisks

Obelisks were first erected in ancient Egypt circa 2100 BC and were the sacred symbol of the sun god of Heliopolis. The shape, a tall four-sided narrowing square section, each side incised with heiroglyphics, and topped with a pyriamid were representitive of a shaft of sunlight. They usually stood in pairs at the entrance to temples.

In the 18th century, oblisks on pedestals appeared as a garden ornament and by the end of the 18th century were also become popular as funerary ornaments in tombs or memorials.

During the Victorian period a pair of miniature obelisks became a favourite souvenir of the Grand Tour. Common sizes varied between 35 cm and 80 cm and they were usually made in various coloured marbles, and more uncommonly in rock crystal, malachite, slate and onyx.

If the description of an obelisk does not include a date, it is likely the item is modern.

Octant

An octant is a historical instrument used in navigation to determine the angle between a celestial body (such as the Sun, Moon, or stars) and the horizon. It was widely used by sailors and navigators in the 18th and 19th centuries for celestial navigation, which involves using the positions of celestial bodies to determine the ship's position and course.

The octant is a predecessor to the sextant, which is a similar instrument but with greater precision. The octant gets its name from the fact that the instrument's arc covers one-eighth of a circle (45 degrees). It consists of a graduated scale, called the arc, and a movable arm called the index arm or horizon bar, which carries a small mirror or prism called the index mirror. By adjusting the position of the index mirror, the navigator can align the image of a celestial body with the visible horizon and measure the angle between them.

The octant allowed navigators to determine their latitude and longitude at sea, which was essential for safe and accurate navigation. While the octant is no longer in common use, it remains an important historical artifact.

Oleograph

An oleograph is a type of print that was popular in the late 19th and early 20th centuries. It is a high-quality reproduction of an original painting or artwork, made using a process called chromolithography. In this process, the original painting is first transferred onto a series of lithographic stones or plates, one for each colour used in the original artwork.

Each stone or plate is then inked with a different colour, and the paper is run through the press once for each colour, creating a full-colour reproduction of the original artwork. The resulting print has a vibrant, almost three-dimensional quality, and can be mistaken for an original painting.

Oleographs were especially popular in the late 1800s, as they offered an affordable way for people to enjoy reproductions of famous paintings and artwork in their own homes. They were often framed and hung on walls, and could be found in homes, hotels, and other public spaces. While oleographs are no longer as common today, they remain a fascinating example of early printing technology and the art of reproduction.

Onion Pattern

The onion pattern is a popular design motif used in the decoration of porcelain, especially in European and Chinese porcelain. It typically consists of a central motif, such as a flower or bird, surrounded by concentric circles of leaves, flowers, and other decorative elements. The onion pattern originated in China during the Ming dynasty (1368-1644) and was later adapted by European porcelain makers in the 18th century, by companies such as Meissen, Royal Copenhagen and Hutschenreuther, and in England by manufacturers such as Royal Wedgwood, Crown Derby and Spode. The name "onion pattern" is thought to have originated from the shape of the central motif, which resembles an onion or a pomegranate. The pattern is often executed in underglaze blue, but it can also be found in other colours such as red, green, and gold.

Onoto Pen Company

Onoto pens were produced in England by the Onoto Company Ltd. from 1905 to 1958. The company was founded by George Sweetser, an American, who had previously worked for the British De La Rue Company, a printing firm that also produced fountain pens. Sweetser started the Onoto Company with the aim of producing a high-quality pen that would be reliable and durable.

The name "Onoto" is derived from the Greek word "onotos," which means "ready for use." The first Onoto pens were fitted with a self-filling mechanism that used a plunger to draw ink into the pen. This was a major innovation at the time, as most pens required the use of an eyedropper to fill them.

In 1907, the Onoto Company introduced the "Onoto Magna," which was a larger pen designed for people with larger hands. This was followed by the "Onoto Minor," which was a smaller pen designed for people with smaller hands.

During World War I, the Onoto Company produced pens for the British military, and the pens were used by soldiers in the trenches. In 1929, the company introduced the "Onoto Plunger Filler," which was a new filling mechanism that used a plunger and a rubber sac to draw ink into the pen.

In the 1930s, Onoto pens were used by many famous writers, including Agatha Christie and Winston Churchill. The company also produced a range of luxury pens that were sold at high-end department stores such as Harrods.

World War II had a negative impact on the company, as it was difficult to source materials and many of the company's skilled workers were called up for military service.

In the 1950s, the Onoto Company faced competition from cheaper imported pens, and in 1958 the company was sold to the De La Rue Company, which had originally employed George Sweetser. The Onoto name was eventually phased out in the 1960s, although the De La Rue Company continued to produce pens under its own name.

In 2005, Onoto was reformed with centralised operations in Colney, Norwich and has been introducing limited-edition historic collections of fountain pens made in and for Britain. The company now exists to preserve traditional craftsmanship techniques of master penman.

Opal Glass

Opal glass, also known as milk glass, is a type of opaque glass that is usually white or cream-colored, with a slightly translucent appearance resembling opal. It is produced by adding various materials to the glass during the manufacturing process, such as tin, fluorides, or phosphates, which give it its characteristic milky appearance.

Opal glass has been used for centuries in the production of decorative objects, such as vases, lamps, lamp shades and figurines. It was particularly popular in the 19th century in Europe, where was used by glass makers such as Lalique.

Opal glass is still used today in the production of a wide range of decorative and functional objects, including lampshades, jewelry, and kitchenware. Its milky appearance gives it a timeless, elegant look that is popular with collectors and enthusiasts of antique and vintage glassware.

Opalescent / Opaline

The descriptions of glass as "opalescent" or "opaline" are often used interchangeably by dealers and auction houses. At the upper end of the scale, opalescent / opaline glass can refer to the opal-like milky blue glass produced by Lalique and Etling. It also refers to the pressed glass mass produced in Britain from the 1840s with a milky white edge as sugar-basins, milk jugs and vases were made in great quantities for the mass market, and were sold at fairs along with Staffordshire figures and wooden dolls. A less common type of opalescent glass was made from two layers of glass blown into a mould.

Open Mouth Doll

An "open mouth" doll is a doll with a mouth that is designed to be open showing moulded or inserted teeth, as if the doll is in the process of speaking or singing. This type of doll was first introduced in the late 19th century and became increasingly popular in the early 20th century. Open mouth dolls were typically made of bisque, a type of unglazed porcelain that is fired at a lower temperature than traditional porcelain. The open mouth design allowed doll manufacturers to create dolls with a more expressive, lifelike appearance, as the open mouth made it possible to add teeth, a tongue, and other features that added to the doll's realism. Open mouth dolls were often dressed in elaborate costumes and accessories, and were marketed to both children and adults as decorative objects.

Openwork in Jewellery

Openwork, also known as pierced work, is a decorative technique used in jewellery making that involves removing or cutting out sections of metal from a piece of jewellery to create a pattern or design. This technique can be used in a wide range of jewellery styles, including necklaces, bracelets, earrings, and rings.

Openwork jewellery can be made using a variety of different techniques, including hand carving, sawing, and laser cutting. The design can be simple or complex, and can feature a range of different shapes and motifs, from delicate floral patterns to bold geometric designs.

One of the advantages of openwork jewellery is that it can add visual interest and depth to a piece without adding a lot of weight or bulk. This can be particularly appealing in larger pieces, such as necklaces and bracelets, where heavy materials can be uncomfortable to wear.

Ormolu

Ormolu was popular with French craftsmen in the 18th and 19th century for ornamental fittings for furniture, clocks and other decorative items. True ormolu is gilt bronze, that is bronze that has been coated with gold using a mercury amalgam. Due to the health risks associated with using mercury, this method of creating ormolu was discontinued in France in the 1830s. A substitute was developed consisting of about 75% copper and 25% zinc, however it was inferior to the bronze version. It was often lacquered to prevent it tarnishing.

Oroton

Oroton is an Australian fashion house that specializes in luxury handbags and accessories. The company was founded in 1938 by Boyd Lane, who started out as an importer of European textiles. In the 1950s, Oroton began to design and manufacture its own handbags, and quickly became known for its innovative use of metallic mesh. The company's signature mesh bags were a hit with Australian women, and Oroton soon became one of the country's leading fashion brands. Embracing the changing fashion trends and consumer demands of the time, the company rebranded as Oroton in 1951, a name derived from "oro" meaning gold in Spanish and "ton" representing the fabric and textiles aspect of the business.

In the 1970s, Oroton expanded its product range to include a wider variety of handbags, as well as other accessories such as scarves, jewellery, and eyewear. The company also began to export its products to other countries, including the United States and Europe.

In the 1980s, Oroton went public and became a listed company on the Australian Stock Exchange. The company continued to grow and expand in the following decades, and by the 2000s, it had over 100 stores in Australia and New Zealand.

However, like many fashion brands, Oroton faced challenges in the ever-changing retail landscape. In recent years, the company went through ownership changes and financial difficulties, leading to the closure of some stores. However, the company has remained resilient and continues to be a leading fashion brand in Australia.

Osier / Ozier Pattern

When used to decorate porcelain, the osier / ozier pattern is a decorative technique that creates a woven or basket-like pattern on the surface of the ceramic. The pattern is created by using a small, pointed tool to incise lines into the surface of the porcelain, creating the appearance of woven strands. It adds a subtle yet interesting texture to the surface of the piece. The pattern can be applied in a variety of ways, such as in a random or structured arrangement, and can be combined with other decorative techniques, such as hand-painted designs or gold leaf accents.

Osrey Pottery

Osrey Pottery was a studio pottery established in Ballarat, Victoria, Australia in 1922 by Gladys Reynell and George Osborne. The name of the pottery was an acronym formed from their surnames.

Gladys Reynell was South Australia's first studio potter and the first Australian artist to apply modernist principles to the crafts. She had studied ceramics at the South Australian School of Arts and Crafts in Adelaide, and was influenced by the work of British potters such as Bernard Leach and William Staite Murray.

George Osborne was a gardener and ex-serviceman. He helped Gladys with the technical aspects of pottery making, such as firing the kilns.

The pottery produced a range of tableware, decorative pieces, and functional objects. The pottery was known for its use of bright colors, particularly the characteristic "Reynella blue" slip. Gladys Reynell's designs were often geometric and abstract, and she experimented with different glazing techniques.

Osrey Pottery operated for four years, closing in 1926. Gladys Reynell continued to work as a potter, and she later established a new pottery in Adelaide. Her work is now highly sought-after by collectors and museums.

Over Upholstered Seat

A Victorian mahogany side chair, circa 1860, with a serpentine fronted over-upholstered seat.

In the mid 19th century coiled upholstery springs came into use and frame of the chair was used as the upholstery frame, making for a much more comfortable and responsive seat. The springs were held in place by webbing and were covered with horse hair, coconut fibre or seaweed with the edges stiched so they were more defined.

This type of seat was known as an over-upholstered or over-stuffed seat

Prior to this, a drop in (or "drop on") seat was commonly used. This was an unsprung removable seat where the upholstery was attached to a wooden frame, which was held in place by the sides of the chair, and usually a wooden peg at the front of the chair. Because the upholstery frame was not very deep, the seats were relatively uncomfortable.

Overglaze on Porcelain

Overglaze decoration on porcelain refers to a decorative technique where designs are painted onto a fired and glazed porcelain surface, and then fired again at a lower temperature to fuse the decorative design onto the glaze surface. This technique allows for a wide range of colors and intricate designs that would not be possible with underglaze decoration, which is applied before the glaze is fired.

Overlay Glass

Overlay glass is coloured glass that has been created by sandwiching two or more layers of different coloured glass together. The layers are fused together through a process of heating and melting in a glass furnace, and the resulting glass has a unique colour and depth that is not found in single-layered glasses.

The technique of overlaying glass has been used for centuries, and was particularly popular in the Venetian glass industry during the Renaissance. Different colours of glass were layered to create intricate designs, and then the layers were carved and etched to create intricate patterns and details.

Owen Jones

 Owen Jones (1809-1874) was a British architect, designer, and writer who played a major role in the development of the Victorian design aesthetic. Born in London, Jones studied at the Royal Academy of Arts and the Royal Institute of British Architects before beginning his career as an architect and designer.

In the 1830s, Jones became interested in the revival of medieval design and the use of historical styles in architecture and decorative arts. He was particularly influenced by the work of Augustus Pugin, who advocated for a return to traditional craftsmanship and the use of Gothic architecture in contemporary design.

Jones became a prominent figure in the Arts and Crafts movement, which sought to promote traditional crafts and design in the face of industrialization. He became involved in a number of important design projects, including the decoration of the Crystal Palace for the Great Exhibition of 1851, where he was responsible for the colour scheme and decorative motifs.

Jones was also a prolific writer on design and architecture, and published several influential works, including "The Grammar of Ornament" (1856), a comprehensive survey of decorative styles from around the world, which is still considered a classic work in the field of design history.

Oxidised (finish in Jewellery)

An oxidised finish in jewellery, particularly gold, refers to a surface treatment that intentionally darkens or blackens the metal surface to create an antique or vintage look. The process involves using a chemical solution to speed up the natural tarnishing or corrosion of the metal, resulting in a dark, matte or semi-matte finish.

In gold jewellery, oxidised finishes are typically applied to lower karat gold alloys, such as 14k or 18k gold, rather than higher karat gold, such as 22k or 24k gold. This is because lower karat gold alloys contain more base metals, such as copper, which are more reactive and prone to tarnishing.

Oxidised finishes in gold jewellery can create a wide range of looks, from a subtle aged patina to a more dramatic blackened finish, depending on the strength and duration of the chemical treatment. This type of finish can add depth and character to jewellery designs, and is often used to create contrast between different elements or textures in a piece.

Oyster Veneer

"Oyster veneer" is a method of veneering occasionally used on antique furniture pieces. It refers to the use of thin, delicate sheets of wood that were cut from the growth rings of a tree to create a decorative pattern that resembles the texture and appearance of an oyster shell.

To create oyster veneer, the woodworker would carefully cut slices of the wood at a slight angle to the grain, so that the annual rings would be visible on the surface of the veneer. The resulting pattern looks similar to the swirling, irregular lines on the surface of an oyster shell, which is where the name comes from.

Oyster veneer was used to embellish high-end antique furniture pieces, such as cabinets, desks, and tables during the 18th and 19th centuries.
