The slightly arcing shapes of these small tubes of green glass, excavated at Essouk-Tadmekka, Mali, suggest they were likely part of small spouted bottles. Made in Egypt or western Asia, such bottles were used throughout the medieval Mediterranean as containers for perfume or rose water. Material remnants of the long-distance trade of luxury glassware, fragments of glass vessels, have also been found at other medieval sites north and south of the Sahara Desert.
