The structure of a hourglass comprises two glass bulbs interlinked with a narrow neck in a vertical position; and held by a wooden or metallic frame. The sand from upper glass bulb pours to the lower one slowly. The sand can be powdered marble, powdered silica, or round & polished sand. Through sand quantity, the exact time can be measured.
