Art Deco Green Depression Glass Footed Cake Plate | 1920s-50s Sowerby UK Pattern 2563

Age of an Item

Antique: An item that is at least 100 years old.

Vintage: An item that is at least 20 years old but less than 100 years old and is representative of its era.

Retro:  A newer item designed in the style of a past era. It is not from that era but is a modern homage to it.

Condition of an Item

Mint: As new, with no signs of wear.

Excellent Vintage Condition (EVC): Shows minimal signs of wear through use but is not perfect.

Very Good Vintage Condition (VGVC): Shows some signs of age and use but is still in good overall shape.

Good Vintage Condition (GVC): Shows clear signs of wear, use, and age.

Perfectly Imperfect: This is not an official term. We've adopted it for the purposes of The Timeless Edit because we believe damaged items still have value. Our definition of Perfectly Imperfect is if an item has visible damage but remains beautiful as a decorative piece or suitable for use in a different capacity from that for which it was originally designed.

Common Flaws found in Antique and Vintage Items

Crazing: Crazing is the existence of web of fine cracks that only occurs in the glaze layer of Fine Bone China and porcelain. It is a normal occurrence, particularly in older items. 

• Clean Crazing: The cracks are clear, without any staining from food, moisture, or other contaminants. Clean crazing can be used as an intentional decorative design element.

• Stained Crazing: This occurs when food particles, bacteria, or other contaminants get into the cracks over time, causing them to darken and become visually conspicuous. Items with stained crazing are not recommended for use with food but are still great for use as a decorative piece or other practical function.

Flea Bite: A flea bite is a tiny, pin-sized chip or nick in the surface of an item. It is a common form of imperfection in older items, especially glass.

Bottom Wear: This is common in older items, especially glass, and is often an indication of age.  Wear to the base of an item is caused by everyday use over time and includes scratches, scuffs, shallow chips, flakes, and flea bites.

 Chip: chips are considered either shallow or deep. A shallow chip is typically inconspicuous. A deep chip is large enough to be immediately apparent.

Flake: a small and shallow chip which breaks the surface of an item.

Scratch: a mark which compromises the surface of an item, and which feels raised, rough or sharp to the touch. Not to be confused with Straw Marks and marks which can occur during the manufacturing process.

Hairline Crack. This is a narrow and tight break going through glaze and porcelain body and is visible from both sides of the item. It is not always immediately obvious and can be missed on first inspection. Generally, a hairline crack does not affect the integrity of the item.

Water Mark/Stain: patches, ridges, deposits and clouding on glass caused by water left standing in the vessel for a lengthy period. Such stains can’t be removed.

Air Bubbles: Air bubbles in hand-blown glass are a natural result of the traditional glassmaking process, where air becomes trapped in the molten glass during its creation. They are often seen as a sign of authenticity, indicating the item is handmade and unique, rather than a defect. While a small number of bubbles is generally acceptable, a high concentration of bubbles may indicate fragility. There are exceptions though. In some cases, air bubbles are an intentional decorative feature where artists have used specific Molds or techniques to control their appearance. Also, air bubbles are found in Depression Glass due to its mass production method, where the glass was quickly moulded with little concern for perfection. These bubbles are a common characteristic that signifies authentic pieces.

Maker’s Miss: This is an unintentional inclusion or air bubble in the item caused or overlooked by the glass blower or maker in the manufacturing process.

Firing Flaw:  This is original flaw cased during the firing process. Examples include pinholes or blisters in the glaze, grit stuck to the glaze, stains caused by an impurity in the porcelain and shrinkage cracks that have opened during the drying or firing process. This is not considered damage.

Straw marks: These are marks on the external surface of glass that look like fine lines or even scratches. They occur when molten glass is cut with shears, and the resulting mark doesn't fully smooth out before the glass cools and sets. They are not considered damage but are instead a common characteristic of old, handmade, or machine-pressed glass. Unlike a scratch, straw marks feel smooth to the touch. Straw Marks are commonly found in Depression and Carnival Glass.

The Story of Sowerby: English Glass with Victorian Elegance

Sowerby holds a prestigious place in English glassmaking history, creating beautiful pressed glass that graced Victorian and Edwardian homes with affordable elegance. Today, these pieces are treasured by collectors worldwide for their quality craftsmanship, distinctive designs, and the connection they provide to England's rich glassmaking heritage.

A Legacy of Victorian Innovation

Founded in 1847 in Gateshead, County Durham, Sowerby's Ellison Glass Works became one of England's most important and innovative pressed glass manufacturers. For over a century, the company produced an extraordinary range of decorative and functional glassware – from elegant vases and bowls to practical tableware and novelty pieces – all crafted with the quality and artistry that made English glass renowned worldwide.

Throughout the Victorian and Edwardian eras, Sowerby brought beauty and refinement to British households. Their pieces weren't expensive cut crystal reserved for the wealthy – they were beautifully designed pressed glass that middle-class families could afford, democratizing elegance and proving that quality design could be accessible to all.

What Made Sowerby Distinctive

The Peacock's Head Mark: Sowerby became famous for their distinctive trademark – a peacock's head – which appeared on most of their pieces from 1876 onwards. This iconic mark became synonymous with quality English pressed glass and remains instantly recognizable to collectors today.

Innovative Colours: Sowerby pioneered distinctive glass colours, including their celebrated "Queen's Ivory Ware" (creamy opaque glass), "Blanc-de-lait" (milk glass), "Patent Queen's Ware" (marbled slag glass), and beautiful transparent colours including amber, blue, green, and purple. Their experimental approach to colour created pieces with remarkable visual appeal.

Victorian Design Excellence: Sowerby's designs captured Victorian aesthetic sensibilities perfectly. Intricate patterns, naturalistic motifs, classical forms, and ornate detailing characterized their output, creating pieces that embodied the era's love of decoration and craftsmanship.

Technical Mastery: Sowerby's pressed glass technique achieved remarkable detail and consistency. Their moulds produced crisp patterns, clean lines, and intricate textures that rivaled more expensive production methods, demonstrating true technical excellence.

Pattern Variety: From the elegant "Dolphin and Shell" to geometric "Basketweave," from naturalistic "Fern and Bamboo" to ornate "Scroll," Sowerby's extensive pattern library showcased Victorian design at its finest.

Why Sowerby is Collectible Today

Over a century after their peak production, Sowerby glass has achieved significant recognition among collectors and antique enthusiasts. Here's what makes these pieces so sought-after:

Historical Significance: Sowerby pieces represent an important chapter in English industrial and design history. They document the Victorian era's democratization of beauty and the development of pressed glass manufacturing techniques.

The Peacock's Head: The iconic trademark makes Sowerby pieces instantly identifiable and highly collectible. Finding that distinctive peacock mark adds authenticity and provenance that collectors value.

Colour Rarity: Sowerby's distinctive colours, particularly their slag glass with marbled effects and their Queen's Ivory Ware, are increasingly rare and prized. Unusual colours command premium prices among serious collectors.

Victorian Aesthetic: As Victorian design experiences renewed appreciation, Sowerby pieces perfectly capture the era's ornate, nature-inspired aesthetic. They bring authentic period elegance to both traditional and eclectic interiors.

Quality Craftsmanship: Despite being mass-produced, Sowerby maintained exceptional standards. Well-preserved pieces showcase remarkable detail, crisp moulding, and durable construction that has survived over a century.

Pattern Diversity: With hundreds of patterns produced over decades, Sowerby collecting offers endless variety. Enthusiasts can focus on specific patterns, colours, forms, or eras, building collections that reflect personal taste and historical interest.

Investment Potential: As English antique glass gains recognition, Sowerby pieces have shown strong appreciation. Rare colours, unusual patterns, and pristine examples command significant prices at auction.

Sustainable Luxury: Collecting vintage Sowerby aligns with circular-economy values. Each piece represents Victorian craftsmanship and English heritage given new life, a conscious choice to cherish what already exists rather than consume new resources.

Identifying Authentic Sowerby

Sowerby pieces produced from 1876 onwards typically bear the distinctive moulded peacock's head trademark on the base, often accompanied by a registration number or design registration mark (the diamond-shaped "Rd" mark used in Victorian Britain). Earlier pieces may be unmarked or bear different marks. The quality of moulding, characteristic colours (particularly the slag glass and Queen's Ivory Ware), and Victorian design aesthetic are reliable indicators of authenticity. Registration marks can help date pieces precisely using Victorian design registration records.

Notable Patterns & Ranges

Sowerby's most collectible ranges include their "Patent Queen's Ware" slag glass in purple, blue, and green marbled effects, "Queen's Ivory Ware" in creamy opaque glass, and "Blanc-de-lait" milk glass pieces. Popular patterns include "Dolphin and Shell" with naturalistic marine motifs, "Fern and Bamboo" featuring botanical designs, "Basketweave" with geometric texture, and various "Pressed Lace" patterns. Their novelty pieces, including animal figurines, posy holders, and decorative dishes, are particularly sought-after by collectors.

Caring for Your Sowerby Glass

These Victorian treasures deserve careful stewardship. Hand wash gently with lukewarm water and mild detergent, avoiding harsh chemicals or abrasive materials that could damage the glass or obscure the peacock mark. Handle with particular care, as Victorian glass can be more fragile than modern pieces. Avoid extreme temperature changes that could cause thermal shock. Display away from direct sunlight to prevent colour fading, especially with purple and blue slag glass which can be light-sensitive. Store with care, using soft padding between pieces. With proper care, your Sowerby glass will continue its journey through homes for generations to come.

At The Timeless Edit, we celebrate Sowerby glass as part of our commitment to circular luxury – honouring Victorian craftsmanship, English heritage, and giving beautiful antique pieces a cherished second chapter in homes that will treasure them.
