Finding very old glassware—such as antique or vintage pieces from the 18th to early 20th centuries—requires a mix of knowledge, observation skills, and some detective work. Here’s a breakdown of how to find old glassware and what key things to look for:
🔍 How to Find Very Old Glassware
- Visit the Right Places
- Estate sales: Often have genuine old household items.
- Antique shops: Especially those with a focus on kitchenware or decorative arts.
- Flea markets and thrift stores: Sometimes yield hidden treasures.
- Online marketplaces: eBay, Etsy, and specialist auction sites like Ruby Lane or LiveAuctioneers.
- Auctions and antique fairs: Great for high-quality or rare pieces.
- Local historical societies or museums: Can offer leads or connections to private sellers.
- Research Beforehand
- Familiarize yourself with popular antique glass styles and makers.
- Learn the eras (e.g., Depression glass, Victorian, Georgian, Art Deco). See below for key differences
- Carry a reference book or use your phone to compare patterns and maker marks.
- Ask Questions
- Inquire about provenance (where it came from).
- Ask about any maker’s marks, damage, or repairs.
Key Things to Look For
- Signs of Age (Wear & Tear)
- Light scratches, especially on the base (called “wear rings”).
- Small bubbles or irregularities from hand-blown or early mold-making.
- Slight asymmetry or thickness variation (typical in older glass).
- Pontil Marks
- A rough or polished scar on the base from when the glass was detached from the blowpipe.
- Usually found on blown glass before the mid-19th century.
- Color
- Certain colors were more common in specific periods. For example:
- Pale green or aqua: Common in early 1800s bottles.
- Deep cobalt blue, amethyst, or vaseline glass (uranium glass): Popular in the late 19th century.
- Depression glass: Often pink, green, or amber (1930s).
- Certain colors were more common in specific periods. For example:
- Mold Lines or Seam Marks
- Hand-blown glass typically has no mold lines.
- Early mold-blown glass (pre-1900) may have soft or faint seams.
- Later machine-made glass (post-1900s) has sharper, more uniform seams.
- Maker’s Marks and Signatures
- Some glass companies etched or stamped logos on the base.
- Signatures may be hard to see—use a magnifying glass.
- Patterns and Cuts
- Intricate cut glass from the American Brilliant Period (1876–1917) is often sharp and deeply cut.
- Depression glass has molded patterns, not cut.
- Pressed glass often has a grainy texture near the mold seams.
- Weight and Feel
- Older glass tends to be heavier and more solid.
- Fine glass may feel smoother and better balanced.
- UV Light Test
- Uranium glass (vaseline glass) glows green under UV light.
- This is a sign of late 19th–early 20th century production.
1. Depression Glass (1929–early 1940s)
Key Characteristics:
- Mass-produced using molds; made during the Great Depression.
- Colors: Pink, green, amber, blue, crystal clear, and some rare colors (e.g. red, black, amethyst).
- Patterns: Pressed or molded floral, geometric, or Art Deco motifs (e.g., “Princess,” “Cherry Blossom,” “Cameo”).
- Lightweight & Thin: Often feels inexpensive—because it was!
- Machine-made: Sharp mold seams, consistent shapes.
- Often Given Away: Found in cereal boxes, movie theaters, gas stations.
How to Spot It:
- Molded patterns rather than cut.
- Cheaper feel, sometimes with rough mold seams.
- Bright translucent colors typical of the 1930s.
Victorian Glass (circa 1837–1901)
Key Characteristics:
- Decorative and ornate: Reflecting the opulence of the Victorian era.
- Techniques used: Hand-blown, cased glass, enamel decoration, etched designs, opalescent glass, milk glass.
- Common types: Bristol glass, cranberry glass, satin glass, uranium/vaseline glass.
- Colors: Rich and varied—deep ruby, cobalt, amberina (red-yellow), opal, and pastel tones.
How to Spot It:
- Decorative techniques like hand-painting or enamel flowers.
- Look for pontil marks (blown glass).
- Irregularities due to hand production.
- Often made for parlors, lighting, or ornamental purposes.
3. Georgian Glass (circa 1714–1830)
Key Characteristics:
- Hand-blown: Pre-dates industrial production.
- Clear lead crystal: Highly prized for its brilliance and ring.
- Simple elegance: Wheel-engraved or facet-cut designs, not overly ornate.
- Glass types: Wine glasses, decanters, and candlesticks were common.
- Baluster and air-twist stems: A key identifier in wine glasses.
How to Spot It:
- Pontil mark on base (usually rough).
- Delicate and light due to skilled hand-blowing.
- Intricate cuts or engraved patterns, but not “busy.”
- Often lacks color—usually clear or slightly tinted.
4. Art Deco Glass (1920s–1930s)
Key Characteristics:
- Bold geometric designs: Zigzags, chevrons, sunbursts, stepped forms.
- Colors: Black, frosted, clear, jadeite, amber, cobalt blue.
- Modernist feel: Angular, streamlined shapes.
- Production: Both hand-crafted and molded.
- Materials: Used both pressed and cut glass techniques.
How to Spot It:
- Think modernist meets glamor—sharp edges, symmetrical lines.
- Often opaque or frosted glass with geometric detail.
- Art Deco patterns may also appear in Depression glass (so overlap exists).
