For domestic use and tableware this high neck bottle has a spherical cap, a technical innovation which allowed for the preservation of the liquids within it. It was produced by the Royal Glassworks of Marinha Grande, which received a royal charter in 1769. The legend on the back VIVAT REX IOSEPHUS 1 [Long Live King José I][Viva Rei José I] celebrates the monarch, adding the Cross of Christ, and in the centre of the bottle, the royal coat of arms.
