COLORLESS CARCHESIUM of Joop van der Groen



Roman Empire, Eastern Mediterranean │ 2nd – 3th century AD
Size: ↑ 9,9 cm; Ø foot 4,8 cm; Ø rim 9,4 cm. │ Weight: 72 gram

Technique: Free blown. Tooled.
Classification: Isings (1957) form 36 b.
Description: Transparent colorless glass with a number of small air bubbles. Body of waisted bell-shaped form. Side wall sharply curving back to slightly concave underside. Bottom pushed in to form a tubular base ring. Pontil mark. Thin glass thread around the body. Rounded rim.
Condition: Intact.
Remarks: Carchesia have been found throughout the whole Roman Empire. La Baume (1974) says: “Carchesia of glass have been blown according to examples in metal.” It is not certain that this form was called carchesium in the antiquity (Isings, 1957).
The basic color 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 0,2 to 1,5 percent antimony oxide the bluish/green raw glass changes into colorless glass. The use of silver or quartz sand also results in colorless glass.
