Description: Transparent dark purple glass. Body with globular sides. Conical shoulder with bulging sides. Cylindrical neck with constriction at bottom. Rim folded outward, upward and inward. Flat base, slightly indented. No pontil mark.
Remarks: These small, typical formed perfume bottles have been made in glass of many different colours, for example in bluish-green, grayisch-green, cobaltblue, purple, amber and colourless glass.
The basic colour of Roman glass is bluish-green. This has been caused because sand (the main element for making raw glass) has been polluted by iron oxide. By addition of some percents manganese oxide in the raw glass the colour changed into purple / aubergine.
