The shape is formed by the union of a convex and a concave line. A mass-produced variant of the shelf clock, the ogee clock stands about 30 inches (75 cm) high and is usually weight-driven. See: American Ogee Clocks
oil gilding (decoration - gilding)
Oil gilding disperses reflected light and appears lighter than water gilding from certain angles. It is done with a varnish or an oil-based gold size that will dry gradually and develop a tacky surface. The gold leaf is simply pressed onto the gold size and it adhears to the tacky surface.The method is used to achieve the matt centre seen in traditional lettering and is used to emulate acid etching.
Usually transfer leaf is used this way. It is easier to handle with less wastage and a bright lustre is not critical. When oil gilding on a surface, the size is usually left tacky as long as possible without actually drying to achieve the best burnish. On glass it not critical as the intention is to achieve a matt finish.
The varnish is sometimes left to dry and then water gilded over with plain gold leaf. This gives more of a satin appearance than direct oil gilding, both of which are useful finishes. It should not be left to fully cure
oil painting (pictures - pigment ground in oil)

Roger Fry belonged to the Bloomsbury Group of writers and artists, members of which, including painters Duncan Grant (1885-1978) and Vanessa Bell (1879-1961), were also involved in the project.
Although the workshops closed in 1919, they heralded a new approach to British 20thC design.

Overlay or cased glass refers to more than one layer of contrasting glass, usually of different colors and with or without a clear layer.
The layers can be put together by several different methods, and frequently are referred to as lining, plating, or flashing. Usually the terms "plating" and "flashing" are applied to glass that has a very thin outside layer.
The Romans knew how to make overlay glass. The famous Portland Vase in the British Museum in London is the product of their skill in design and glassworking technique. A shell or cup was formed and set in a container while a gather of a contrasting color was quickly and gently blown into it. The two were fused and the article finished according to the decorative effect desired.
A quicker method of casing is usually called flashing, that is, a gather of one glass is covered with a gather of a contrasting color, and then finished. Using this method a thinner layer of one of the glasses cand be used, saving costly material such as gold-ruby glass.
During the 1860s cased glass cut in patterns was popular for vases, lamps, scent bottles, and other items. The outside layer of opaque white was cut through to form a pattern on the colored layer beneath.
The designs were simple all-over patterns. The cutting of the pattern required a steady hand and accurate eye. This glass is a favourite of collectors.
Cameo glass is a cased or overlay glass where the outer layer forms the design.
The Portland vase is an outstanding example. The undercoat is the background. A great deal of skill is required to make cameo glass using the old process of hand grinding on a rotating wheel. The use of hydrofluoric acid in the latter part of the nineteenth century eliminated or reduced the handcrafted skill to a minimum.
