Art Deco Style Bagley Glass Vase with fin type handles 1930s
Price: £45
Daum Crystal Glass Swallowtail Bowl, signed Daum-France circa 1960
Price: £150Vases in this form were produced by the well known French maker Daum in the 1950s and the 1960s. The sizes and designs can vary with some examples measuring up to two feet and intended as table ornaments. This piece is rather smaller and perhaps more elegant. The crystal glass is of extremely high quality and reflects the light in a very attractive way. The weight is good and the glass itself is thickly blown and expertly formed, The flat base shows signs of bevelled edging at the exterior and one of the sides bears the typical etched Daum mark with 'Daum' and 'France' separated by a device comprising an upright line with two crosses.
The more petite size and the quality of the manufacture and design make this a most appealing example of Daum's work at its best. Dating can be assumed to be around 1960 if not slightly before. A desirable piece indeed for collectors of twentieth century art glass.

A Blue Glass Icicle Bowl, designed by Tauno Wirkalla for Humppila Finland, late C20th
Price: £150Tauno Wirkalla was the brother of the celebrated Finnish designer Tappio Wirkalla and like him favoured an ‘ice glass’ effect in his designs. He was one of the designers for the Humpilla Glassworks in Finland which was founded by the Helander brothers in 1952 and was then subject to various takeovers, finally being acquired by the firm Nuutajarvi (for whom the Helander brothers had originally worked) in 1986. Wirkalla produced many ‘ice glass’ designs for Humppila, some of which are signed and some still surviving with their factory labels, which is not the case here. This bowl is of an exceptionally large size and has miraculously survived undamaged with all its pointed edges intact. A truly distinctive centrepiece recreating the style of an earlier era.

Cranberry art glass Vase, probably Chřibská, Josef Hospodka, Czech late C20th
Price: £55This design is generally attributed to the designer Josef Hospodka (1923-1989) who worked for the Chřibská glassworks in Czechoslovakia from 1950 to 1970 and again from 1985 to 1989. His organic, sculptural blown glass designs enjoyed great popularity and some remained in production after his death until the factory closed in 2007. There are catalogues from the factory and some of the pieces were also illustrated in the Czech Glass Revue where they were directly attributed to Hospodka. There does not appear to be either a catalogue entry for this vase or any mention of it in the journal, but the general style is extremely close to known works by him and the attribution is reasonably safe. Chřibská pieces were distinguished by their vibrant colours, flowing forms, weight and a smooth polished base, all of which are present here making this a fine example of their productions.
Murano style Art Glass Paperweight, second half C20th
Price: £45
Davidson Glass Topaz Briar Table Centrepiece, 1930s
Price: £45George Davidson founded the Teams Flint Glass Works in 1867, which later became known as George Davidson & Co. In the 1880s the company began producing pressed glass tableware in a variety of shapes and by the 1920s their designs began to reflect the new Art Deco trends. The firm continued production until the 1980s, closing in 1987. Some of their catalogues still exist and one from the early 1930s shows a piece very similar to this one (see image 11). The colour is known as ‘Topaz Briar’ and the swirling effects resemble other pieces in their ‘cloud glass’ range, a pattern for which the firm was famous.
The colourings and small size of this piece make it an unusual find amongst the Davidson wares which can be seen today and the presence of all three elements (perfect and complete) make it a desirable addition to a collection of twentieth century pressed glass.

Cranberry Glass Vase circa 1900
Price: £30
Black and Gold Copper Glitter Art Glass Scent Bottle, probably Murano late C20th
Price: £55
Sowerby Amber Glass Centrepiece circa 1930
Price: £75The Sowerby family came from the North West of England near Carlisle and settled in Gateshead in the late eighteenth century. The firm Sowerby Glassworks is known from 1807 onwards and continued production until 1972, concentrating on pressed glass. Catalogues of their wares still exist and they produced pieces in a wide variety of styles and shapes which retain their popularity today.
The centrpiece figurine, which was intended as a flower holder or ‘frog’, is rather unusual; normally the figures are female but the style of the modelling is identical. Similar designs to the bowl can be found in a 1936 catalogue but versions of it even appear in another catalogue from 1882. Many centrepiece/bowl combinations are found and some of them are not always original. This may possibly be the case here but if so the ‘match’ is extremely pleasing to the eye and the two elements set one another off perfectly to produce a striking example of Art Deco decorative design.

Wylde Green Perfume Bottle, Lesley Ann Clarke Glass, signed and dated 2019
Price: £75The signature at the base is for Lesley Ann Clarke, a glassmaker based in St Ives, Cornwall (see image 8). She writes herself “Over the years many artists and craftspeople have come to live in Cornwall for its light and wondrous views. I was born here and knew no other. My work with blown glass makes full use of the light and the flowing nature of hot glass. To grow up in St Ives is an art lesson in itself.” Her work is exhibited at various galleries in the UK and all her pieces employ individual naturalistic designs in variety of shapes and colours of which this perfume bottle from the ‘Wylde Green’ range, dated to 2019, is an excellent example.

Golden Amber Webb Glass Vase, marked, 1950s
Price: £45Thomas Webb began his glass career in 1829, when he became a partner in the Wordsley Glassworks. Various career changes followed and in 1859 he was joined by his sons Thomas Wilkes Webb and Charles Webb and began trading as Thomas Webb & Sons based in Stourbridge. The firm was run by various family members until mergers started to occur in the early twentieth century and Sven Fogelberg, previously from Swedish glassworks Kosta, became manager in 1932. Production continued with more mergers in the 1960s and 1970s until the firm closed in 1990. This vase was made by Thomas Webb during the 1950s as part of their 'Gay Glass' range in a design called 'Old English Bull's Eye' and has the typical 'Webb England' mark to the base.

Kosta Boda Bowl, designed by Anna Ehrner, with label, second half C20th
Price: £45Kosta Boda, previously known as Kosta Glasbruk, is a Swedish glassmaking company founded by two foreign officers in Charles XII's army, Anders Koskull and Georg Bogislaus Staël von Holstein, in 1742.It is located in Kosta, Sweden. Early production consisted of window glass, chandeliers and drinking glasses. From the 1840s, the factory was at the forefront of new trends and technical developments, producing pressed glass, and in the 1880s setting up a new glass-cutting workshop. In 1903, the company merged with the Reijmyre glassworks but both retained their own names and Kosta went on to maintain its reputation as one of the leading Swedish manufacturers with a range of fine art glass and tableware by distinguished designers.
Anna Ehrner, born in 1948, has been associated with the firm since 1974. This bowl is from the ‘Contrast’ range and is made using a technique called centrifugation which creates trails of colour inside the glass body. While the design is still produced today, it is no longer available in this size and the lines here are more angular than those found in the modern examples, suggesting a dating to the late 1970s or 1980s soon after Ehrner began working for Kosta Boda.
Twister glass Bowl, Kjell Engman for Kosta Boda, signed and with label, late C20th
Price: £180Kosta Boda, previously known as Kosta Glasbruk, is a Swedish glassmaking company founded by two foreign officers in Charles XII's army, Anders Koskull and Georg Bogislaus Staël von Holstein, in 1742.It is located in Kosta, Sweden. Early production consisted of window glass, chandeliers and drinking glasses. From the 1840s, the factory was at the forefront of new trends and technical developments, producing pressed glass, and in the 1880s setting up a new glass-cutting workshop. In 1903, the company merged with the Reijmyre glassworks but both retained their own names and Kosta went on to maintain its reputation as one of the leading Swedish manufacturers with a range of fine art glass and tableware by distinguished designers such as Vicke Lindstrand, artistic director from 1950-1973.
Kjell Engman (see image 11) has been a designer at Kosta Boda since 1948. Also a professional rock musician, his works are often held to display a dancing feel and joie de vivre derived from his musical background. On the Kosta Boda website he writes “In my view, the glass is the pen for writing my stories. I don’t want to depress my audience; rather, I want to offer them joy and fantasy. My art should make people smile; it should be something positive.” Perhaps something of his sense of fun can be seen in this bowl, one of the largest of the range produced by Kosta Boda. which incorporates colour with movement and is often termed ‘Twister’. These bowls seem not now to be available from the firm direct and probably date to the late twentieth century. This example is of exceptional size and in pristine condition, an imposing centrepiece for a modern interior.

Phoenician Glass Vase, signed, late C20th
Price: £45Phoenician Glass was founded on Manoel Island, Malta in the 1980s by Leonard Sullivan, who had worked previously at Mdina Glass and many of his designs resembled those of his old employers. Certainly, the influence of Mdina and perhaps that of one of its founders, Michael Harris, can be seen here. Phoenician Glass took its name from the ancient Phoenician civilisation, which colonised Malta during the first millenium BC.

Spatter Glass Basket with thorn rope twist handle, probably Stourbridge, late C19th
Price: £75The 'spatter’ technique was known from Roman times but enjoyed something of a renaissance in the Victorian era when there was a general revived interest in the glass making techniques of the ancient world. Similar baskets are normally associated with the glassmakers at Stourbridge, Worcestershire, a centre of glass production since the 1600s, and this seems the most likely source of this piece, with a dating to the late nineteenth century. It is an excellent example of the type and remains in fine condition.
Mdina Earthtones Pattern Vase, late C20th
Price: £85Mdina Glass was founded in the Maltese town of Mdina in 1968 by Michael Harris and Eric Dobson. The town had no history of glass making but the venture proved to be a success. Its wares, free formed organic glassware, often in colours inspired from the sea, sand, earth and sky, proved very popular with tourists visiting Malta. Michael Harris left Mdina in 1972 and formed a new company, Isle of Wight Studio Glass, on the Isle of Wight, UK, leaving Eric Dobson in charge, but many of the designs he created continued to be made at Mdina Glass after his departure although new designs and patterns were added as well of which this vase is an example. Ownership of the company later changed but it is still producing a popular range of glasswares today.

Art Deco style kneeling figure of a Girl, Aquincum Hungary, second half C20th
Price: £75Aquincus was an ancient Roman settlement, eventually to become the town Obuda, the third of the three cities which were merged to form Budapest and the oldest district in the Hungarian capital. In 1854, Hüttl Tivadar set up a shop in Pest selling porcelain eventually becoming involved in porcelain manufacture itself with such success that by the early 1900s he was supplying the court at Buda, eventually supplanting the rival firm of Herend. Despite legal battles amongst the family concerning the ownership of the business, the firm continued to prosper until the 1950s when the new communist government decided to nationalize the factory, renaming it Aquincum Porcelángyár. Tableware, which had been the staple of the Hüttls’ production was replaced by figurines which rapidly enjoyed great popularity. One of the principle artists was Antonia Szabó who became chief designer in 1966. With the end of socialism, the firm went into private hands in 1993 but suffered an immediate and rapid decline causing it to close soon after.
This figure may possibly, then, have been designed by Szabó himself but it is certainly typical of the pieces produced in the early years of state control and perhaps one of the most appealing. The form of the mark corresponds with a dating to the 1950s or 1960s and the piece has both historical associations and considerable decorative appeal.
Two Amelia Art Glass Vases, Apple and Pear

Art Deco Flower Vase, Frog and Stand, Bagley Glass, Spinette Range, 1930s
Price: £45Bagley Glass was established in Knottingly, England (south east of Leeds) in 1871. Bottle makers at first they branched out in 1912 and opened a department 'The Crystal Glass company' which made crystal and pressed glass. But it was for the latter that Bagley were to become famous and they became the biggest manufacturer of pressed glass in England in the years before and after the war. Many of their designs were influenced by the Art Nouveau styles and this flower vase, unusually presented complete with its frog and stand, is a classic example of their range.

Blue and Green Ice Glass Square Bowl, designed by Tapio Wirkalla for Iitala Finland, late C20th
Price: £55The Finnish designer Tapio Wirkkala (1915–1985) was a major figure of post-war design, working in a wide variety of media including ceramics, wood and glass as well as postage stamps, bank notes and even light bulbs. His first piece for Iitala was produced in 1946 and the commercial ‘Tapio’ collection from 1954. Some of his ‘ice glass’ effects took the Iitala craftsmen many hours to perfect the glass blowing techniques required to produce them but enjoyed immense popularity. These chunky bowls, almost brutalist in style, were produced in the 1970s and 1980s and are an excellent example of his work for the popular market.
Two Wedgwood Glass paperweights designed by Ronald Stennett-Wilson, late C20th
Price: £40
Frosted art glass lollipop form vase, Peter Layton, signed, late C20th
Price: £150Peter Layton is one of Britain’s most celebrated glass artists. Born in 1936, his initial interest was in ceramics but in 1965, while on a teaching post at the University of Iowa, his focus changed and he began to study the art of glass blowing, at a time when the art glass movement in America had an enthusiastic following. Returning to England in 1968, he started a a small glass studio in the Highlands of Scotland while relying on pottery to earn a living. Eight years later, in 1976, he opened the ‘London Glassblowing’ studio which continues to this day and where Peter Layton, now in his eighties, continues to train and supervise upcoming glass artists as well as producing his own work.
This vase is probably one of his earlier pieces and derives its inspiration from the celebrated glass workshops at Mdina and the Isle of Wight whose productions tended to draw heavily on landscape and nature and some of whose shapes clearly influenced it. There are a few other pieces in a similar form, but the colourings and design here are particularly pleasing making this a highly desirable addition to a collection of British studio glass.

Loetz style glass Bowl, early C20th
Price: £110Most of the original Loetz pieces were not signed and there were many contemporary manufacturers making pieces in a similar style. There are, furthermore, modern reproductions. The attribution ‘Loetz’, is, inevitably, generously and loosely applied but sometimes true certainty is hard to achieve. Much information and assistance can be obtained from the website Loetz.com. On that basis this attractive bowl with its crimped rim and wavy line design on a purple ground is best regarded as Loetz style but probably contemporary with the output of the Loetz factory itself. It has great decorative appeal nevertheless.

Beehive form glass vase with a swirl design, probably by Charlie Meaker, late C20th
Price: £75Charlie Meaker was born in Montana, USA, in 1946. After graduation in 1968 and a spell as an Olympic skiing coach, he studied glass design in England, Canada and Sweden before settling in the UK where he taught at Sunderland before moving to Copenhagen where he spent the last twenty years of his life. His work can be found in museums in the UK, Norway, the Netherlands and the USA and is collected today. A former colleague wrote, ‘He was brilliant at energizing people and pulling together groups of creative people to make beautiful glass. He made things happen. He made workshops and studios happen. ... Charlie was a very humane man: demanding, mercurial, funny, stubborn, loyal, infuriating, committed, intelligent, questioning and tireless’.

Perfume Bottle and Stopper, Stuart Akroyd, signed J S A, late C20th
Price: £75The signature here, which occurs on other pieces by the same artist, is for Stuart Akroyd, a celebrated English glassmaker who worked from studios in Sunderland then Sheffield from 1991 to 2021(see image 8). Born in 1966, Akroyd studied at Sunderland University, following this with a Post Graduate Diploma at the International Glass Centre, Brierley Hill. After working as the head maker at Lakeland Crystal, Cumbria he went on to establish his own business, Stuart Akroyd Glass Designs, in 1991, renaming it Stuart Akroyd Contemporary Glass when he moved from Sunderland to Sheffield in 2000. Best known for his sculptural pieces which were inspired by the ‘Skylon’ structure, the well known symbol of the 1951 Festival of Britain, Akroyd also worked on a smaller scale and there a number of small bottles by him of which this is an excellent example. The glass effects are skilful and inventive and the flat panel to the body is both decorative and functional, allowing the level of fluid in the bottle to be seen clearly. Many of his sculptural pieces were made in his later Sheffield workshop which, with its greater space, allowed him to employ the techniques necessary to create them, so it is a reasonable guess that this bottle and its companions belong to the first phase of his output.
Mdina Blue Summer Perfume Bottle and Stopper, signed, 1970s
Price: £55Mdina Glass was founded in the Maltese town of Mdina in 1968 by Michael Harris and Eric Dobson. The town had no history of glass making but the venture proved to be a success. Its wares, free formed organic glassware, often in colours inspired from the sea, sand, earth and sky, proved very popular with tourists visiting Malta. Michael Harris left Mdina in 1972 and formed a new company, Isle of Wight Studio Glass, on the Isle of Wight, UK, leaving Eric Dobson in charge, but many of the designs he created continued to be made at Mdina Glass after his departure. This perfume bottle may possibly be an original Michael Harris design. Certainly it reflects the organic forms he created and the colourings, resembling the popular ‘sea and sand’ range, are consistent with this although the pattern here is more correctly referred to as ‘blue summer’ and the stopper of this bottle is a better match in colouring and design than some of the other examples currently on the market.

Its wares, free formed organic glassware, often in colours inspired from the sea, sand, earth and sky, proved very popular with tourists visiting Malta. This vase is one of the earlier productions made by Mdina (the format of the signature confirms this) probably dating to the 1970s and, if not designed by Michael Harris, it certainly resembles the organic forms he created and the colourings, often referred to as ‘sea and sand’ although more correctly termed ‘blue summer’, reflect this. The raised detail to the sides enhances the overall profile contributing to a piece of satisfying charm.
Mdina tiger pattern glass Vase, signed, second half C20th
Price: £45Mdina Glass was founded in the Maltese town of Mdina in 1968 by Michael Harris and Eric Dobson. The town had no history of glass making but the venture proved to be a success. Its wares, free formed organic glassware, often in colours inspired from the sea, sand, earth and sky, proved very popular with tourists visiting Malta. This vase is one of the earlier productions made by Mdina (the format of the signature confirms this) probably dating to the 1970s. The design is known as the ‘tiger pattern’ and is believed to have been created by Eric Dobson himself. All the pieces in the range have individual variations but this particular version is extremely pleasing and highly characteristic of Mdina’s naturalistic style.

An art glass Perfume Bottle and Stopper, Martin Andrews Glass, C21st
Price: £75Martin Andrews (see image 9) graduated from West Surrey College of Art and Design with a BA (hons) Glass in 1991. Following this he was based in London until 2000 when he then launched his current workshop at the Ruskin Glass Centre in Stourbridge. His work often draws on the earth's natural forms and patterns and his ‘beach’ range is a prime example of this. Most of his pieces are signed, but this bottle is not, perhaps because of its size, but its inclusion in the studio’s inventory makes its provenance beyond doubt.
