Glassware ID: 9 shapes that separate decorative from valuable
Glass can look “plain” in one light and collectible in another. Use this collage as a fast visual reference for common shapes and glass categories buyers talk about. When you find a close match, photograph the rim, base, and any seams or pontil marks—those details usually matter more than the overall silhouette. Value depends on maker, age, rarity, and condition, but good photos make identification much easier.
Legend (tiles 1–9)
- Cut crystal bowl — sharp facets, heavy feel, and a starburst base; photograph the base pattern and any maker mark.
- Art glass vase — smooth surfaces with internal color ribbons; check for a polished pontil on the base.
- Pressed glass cake stand — repeating molded pattern; look for mold seams and a more “soft” edge to details.
- Stemmed wine glasses — thin rims and consistent proportions; check for chips, clouding, and etched signatures.
- Cranberry glass decanter — rich red/pink tint with a stopper; photograph the neck, stopper fit, and any applied decoration.
- Milk glass compote — opaque “opaline” look; examine the rim and foot for wear, and note any maker stamp.
- Etched glass vase — frosted floral or scroll designs; a close-up of the etching helps separate hand work from acid-etching.
- Decorative paperweight — dense glass sphere with internal dots/flowers; photograph the base (often ground flat) for signatures.
- Amber oil lamp base — antique form without chimney; inspect metal fittings, burner threads, and any cracks.

How do I tell pressed glass from cut crystal?
Cut crystal usually shows crisp, sharp facets and often a starburst base pattern; pressed glass shows repeating molded patterns and may have visible mold seams. Weight can help, but seam/pattern evidence is more reliable than “feel” alone.
What photos should I take to identify glassware?
Take a straight-on full view, then close-ups of the rim (chips), base (pontil, pattern, marks), and any seams/joins. Include a ruler or coin for scale, and photograph in both natural light and indoor light to show color.
Do bubbles mean the glass is old?
Not always. Some older pieces show bubbles or waviness, but modern studio glass can also have intentional bubbles. Use multiple clues: pontil finishing, seams, wear, and any signatures.
Is milk glass valuable?
It can be—especially certain makers, colors, shapes, and sets in clean condition. Chips, heavy scratches, or dishwasher clouding can reduce value, so condition details matter.
How should I clean older or delicate glass?
Hand-wash with mild soap and lukewarm water, avoid abrasives, and skip the dishwasher for thin rims, gilding, or fragile applied details. If the piece has a metal burner or fittings, avoid soaking metal parts.
