Glass became very popular across the Roman Empire, especially after the discovery of glassblowing in which production rates rapidly increase to match the level of demands. Glassblowing not only allowed for a wider range of styles and shapes to be produced but the translucency of the glass became more achievable. This method revolutionised glass production thus changing the everyday trends, people became more favourable of glass cup rather than pottery ones. Two different trade businesses were involved with the manufacturing of glass, glassmakers and glassworkers. The glassmakers would melt down glass and when cooled, it would be broken into chunks and shipped to glassworkers. Once receiving the glass, the glassworkers would mould it into the desired vessel/object. The function of these objects varied in everyday life, smaller bottles such as unguentarias would hold essential oils and perfumes while larger vessel, like this jug, would be filled with drinking liquids and placed on tables. Glass vessels were also used for storage, merchants would pack different food products and goods in them and ship them overseas.
