## What you would see

Centered against a soft gradient from dark charcoal at the top to pale light gray below, a clear lidded glass vessel stands upright. The body is tapered, wider at the rim and narrower toward a thick, rounded foot, all hand-blown with subtle thickness variations and tiny trapped air bubbles. The glass is transparent with gentle highlights along its edges. The lid is tall and steeply conical with a wide, stepped flange that rests on the rim, topped by a teardrop finial with a small collared ring at its base. On the front wall, an opaque white wheel-engraved decoration stands out: a large central stylized tulip with pointed petals, flanked by scrolling tendrils and two sprays of feathery foliage with small hanging berries or buds. Wavy engraved borders extend to either side of the upper flower. Front lighting creates a soft shadow beneath the base and emphasizes the contrast between the glossy clear surface and the matte etched ornament, while faint reflections define the curvature of lid and body.

## How to look at it

Start with the overall silhouette and the pointed finial, then move down to the frosted engraving. Notice how light passes through the clear wall and reveals tiny bubbles from blowing. Look closely at the slightly irregular symmetry of the tulip and scrolls, a sign of hand work.

## Context

According to Cleveland Museum of Art records, this is a Flip Glass by an unknown maker, dated to the late 1700s and attributed to America, late 18th century, classified as Glass in the Decorative Art and Design department. The source description provides no further details. Flip glasses were lidded vessels for a popular colonial hot drink made of beer or cider, rum and beaten egg, kept warm by the cover. The engraved floral motif is typical of German-American glass of Pennsylvania, where craftspeople of German descent decorated blown glass with wheel-engraving. The exact workshop for this piece is not known.

## Curious detail

Lidded flip glasses were used for flip, a colonial tavern drink that was frothed by plunging a red-hot iron called a loggerhead into the mixture of beer and rum.

- What does the lidded form suggest about temperature, sharing and ritual around drinking in the 1700s?
- What can a single stylized flower tell us about cultural exchange in early America?
