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.
