merese

A merese is a small, flattened disc or button of glass that sits at the junction where the stem of a drinking glass meets its foot. It serves both structural and visual functions, spreading load where two separate pieces of glassware are joined and creating a visual break in the glass profile. The merese is typically wider than the stem itself, sometimes reaching 40 to 60 millimeters in diameter on larger glasses, though on delicate pieces it may be barely 20 millimeters across.

In traditional glassmaking, the merese appears on stemmed vessels made by joining separately formed components: the bowl, stem, and foot are created individually, then fused together using heat. The merese acts as a reinforcement at the critical joint, reducing stress concentration where the narrow stem would otherwise meet the wider foot directly. Without it, the junction becomes a weak point prone to cracking under thermal shock or mechanical stress. For this reason, merese are especially common on handmade glasses and on pieces designed for frequent use.

The merese can be simple and sharp-edged, ground flat on both surfaces, or slightly domed and polished smooth. Some decorative versions feature cutting, molding, or pattern work. The quality of the merese often indicates manufacturing standards: a well-finished merese suggests care taken throughout production, while a rough or chipped one signals either poor workmanship or hard use over time.

The term derives from Italian merése, reflecting the vocabulary of Venetian glassmakers who refined this technique. The merese became a standard feature in English and European glassware from the seventeenth century onward, particularly on wine glasses and chalices. It remains a diagnostic feature for dating and valuing antique glass: its presence, proportions, and finish help identify the period, origin, and intended market of a piece.
