Antique Glassware Identification Guide
Color, pattern, and weight are the fastest ways to sort genuine Depression-era glassware from later reproductions.
Color as a first clue
Depression glass was produced in distinctive colors — pink, green, amber, and a pale blue among them — often with slight bubbles or imperfections from the era's manufacturing process. Reproductions tend to have unnaturally uniform color and no bubbles.
Weight and pattern
Genuine pieces from makers like Fire King and Pyrex often feel lighter than modern reproductions of similar patterns. Comparing the same pattern across multiple booths — easy to do at a large venue like Saugatuck Antique Pavilion — helps you calibrate what "right" feels like.
Check for maker's marks
Many pieces have a maker's mark molded into the base. Cross-reference it against known mark guides before assuming a piece is unmarked and therefore unidentifiable.

Pink, green, amber, and pale blue are common, often with small manufacturing imperfections rather than perfectly uniform color.
Are Pyrex and Fire King the same thing?
No — they're different manufacturers with overlapping mid-century popularity, each with distinct marks and pattern lines worth learning separately.
