Unguentaria were amongst the most common objects of Roman blown glass: produced in large numbers, they were items of everyday use for keeping expensive unguents and cosmetic oils. By the 1st century AD, the technique of glass-blowing had revolutionised the art of glass-making. This glass bottle was formed from a combination of casting and blowing produced in the period before glass blowing popularity. Its method included cane and rods of pre-formed coloured glasses being arranged and fused together through reheating. The glass was then manipulated to create unique ribbon-mosaic glass. The surface of such glasses tends to be rougher due to the nature of the creation, creating entirely unique pieces.
