2nd – 3rd century AD | Eastern Mediterranean

Size↑12.0 cm | ø 6.0 cm | Weight 34 g

Technique: Free blown, tooled

Classification: Isings 1957 form 82 (variant)

Description: Two bottles fused together creating one and oval-shaped body without an inside wall. One bottle made in colorless glass and the other in pale green glass, long and narrow tubular neck. Rim folded outward and inward. No pontil mark.

Condition: Intact with iridescence, some incrustation and fine hairline cracks in body.

Remarks: This is an extremely rare example of an experiment(?), conducted by a Roman glass blower somewhere during the 2nd or 3rd century AD. Perhaps intended as a joke or as the result of an accident. Two authentic unguentaria blowing from different colored glass bubbles into two regular formed bottles of which the bodies join each other forming one undivided body, like a Siamese twin. By bringing a small light into the neck it is very well visible that there is no connection seam or mark between the two different bodies, so it is undeniably one large and squat blown body with two different colored body sections of glass. Very strange and a real puzzle to understand how they made it. Where the mouth edge of the green bottle is attached to the colorless bottle, a part of the rim is omitted by the glass blower to get a better adhesion. To adhere the two mouths together the glass blower forced applying the mouth of the colorless glass. He tooled it by using a hand-held tool and the marks of that tool are visible on the rim which is somewhat distorted. Another remarkable detail relates to the bottom of the colorless bottle which is not flattened as is rather common. It means that this bottle was blown and fused together with the greenish one, when they were not finished yet.
