Glass sand timer, an hourglass with clear glass bulbs filled with purple sand, set in a polished gold-toned metal frame. Three slim pillars topped with round ball finials join a round top plate to a round base plate, and a gold-toned collar holds each end of the glass. A sand timer measures a set stretch of time as the sand runs from the upper bulb to the lower one, then turns over to start again. Material: Glass (Glass Wares range).
