A Collector's Guide from The Wonder Room
Georgian wine glasses — made between approximately 1714 and 1830 — are among the most valuable, collectable and rewarding areas of antique glass interest. Beautifully proportioned, individually crafted, technologically innovative and rich in variety, a genuine Georgian wine glass is a tangible connection to the golden age of English glassmaking and a genuine link to those who used them before us. But how do you tell the real thing from a Victorian glass or a later reproduction?
Understanding the Georgian Period
The Georgian era saw English glassmaking reach its peak. The repeal of the Glass Excise Tax in 1845 (just after the period ended) had not yet flooded the market with cheap pressed glass, so Georgian pieces were made by skilled glassblowers using lead crystal — a material that gives genuine Georgian glass its characteristic weight, brilliance, and 'bell-chime' tapped resonance.
Tap a genuine Georgian wine glass gently with your fingernail. It should ring with a clear, sustained bell-like tone. Pressed or modern glass produces a dull, flat sound.
The Bowl
Georgian wine glass bowls come in a wide variety of forms — tulip, round funnel, waisted, ogee, bucket, trumpet etc— each associated with different periods and styles. Key things to look for:
- Hand-blown construction: The bowl will have a slight irregularity when examined carefully — no two hand-blown bowls are identical. Look for very subtle variations in thickness and form. Held up to the light, clear striations in the glass can often be seen.
- Pontil mark: Where the glassblower's rod was attached, you will find a pontil mark on the base of the foot — either a rough scar or a polished depression. Its presence is a strong indicator of hand-blown manufacture.
- Engraving: Many Georgian glasses feature wheel-engraved decoration — vines, hops, birds, or commemorative motifs. Genuine engraving has a soft, slightly frosted quality. Be cautious of engraving that appears too sharp or mechanical.
The Stem
The stem is often the most diagnostic feature of a Georgian wine glass. Key stem types include:
- Baluster stems (c.1685–1725): Heavy, bold forms with knops and balusters — the earliest and most architectural style.
- Air twist stems (c.1745–1770): Contain spiralling columns of air trapped within the glass — hold the glass up to the light and rotate it slowly to see the twist clearly.
- Opaque twist stems (c.1755–1780): White enamel threads twisted within the stem — extraordinarily skilled work that is very difficult to reproduce convincingly.
- Facet cut stems (c.1770–1810): Diamond or hexagonal facets cut into the stem, reflecting the neoclassical taste of the later Georgian period.
Examine the stem carefully for any joins or repairs — a genuine Georgian glass is made in one continuous piece from foot to bowl.
The Foot
The foot of a Georgian wine glass is typically folded (with the rim turned under to create a double thickness) on earlier examples, or plain and slightly domed on later ones. Key indicators:
- The foot should be hand-finished and show slight irregularity
- A folded foot is almost always a sign of pre-1750 manufacture
- The pontil mark on the underside of the foot is your most reliable indicator of hand-blown, pre-industrial manufacture
- There are often tiny bubbles or inclusions of grit or soot to be seen within the glass.
Weight and Feel
Lead crystal — used in virtually all quality Georgian glassmaking — is noticeably heavier than modern glass. Pick up the glass: it should feel substantial and satisfying in the hand. The brilliance of lead crystal also gives Georgian glass a particular clarity and depth that catches the light beautifully.
What to Watch Out For
Reproductions of Georgian wine glasses have been made since the Victorian era. Later copies tend to be lighter, more uniform, and lack the subtle irregularities of hand-blown work. The pontil mark is often absent on reproductions. Opaque and air twist stems have been reproduced, but close examination usually reveals a regularity and perfection that the originals — made entirely by hand — do not have.
Damage is common on genuine Georgian glass — small chips to the foot rim, minor wear to the base. A glass in suspiciously perfect condition warrants closer scrutiny.
Why Collect Georgian Wine Glasses?
Georgian wine glasses represent one of the most accessible entry points into serious antique collecting. Fine examples can still be found at auction, in antique shops, and at fairs for very reasonable sums — and they are as beautiful in use as they are on display. There are rarities to look out for, such as early small production designs and forms, unusual air twist stem configurations, specialty and Jacobite glass engravings and each one is a unique, handmade object that has survived two or three centuries of use.
