Glass krater (mixing bowl)

Translucent deep honey yellow.
Outsplayed horizontal rim with slightly rounded edge; hemispherical body with convex curving sides; small, slightly convex bottom on interior; applied tall, outsplayed base with a solid, cylindrical stem with slightly concave profile, a deep concave bottom, and a thick vertical outer edge.
On upper edge of rim, two broad concentric grooves; on interior, a single broad horizontal groove below rim; on exterior, three concentric grooves around bottom and applied base; on base, a single broad horizontal groove below stem, another around top of outer edge, and a third groove in vertical edge.
Broken and repaired, with many small areas missing, especially in body; a few pinprick and larger bubbles; patches of thick creamy weathering and elsewhere some dulling and iridescence.
Rotary grinding marks on interior and exterior of both body and base. One small jagged piece of same-colored glass is attached to the bottom of the base.

This large footed bowl, possibly used for mixing wine, belongs to a small group of luxury glass vessels that remains problematic, for neither their date nor their place of manufacture have yet been precisely ascertained.
