The technique of mold-blowing all so called mold-blown is a very old method used to make glass containers and objects. A molten glass parison (bubble) on the end of a blow pipe is blown into a mold to give shape and decoration to the vessel.  It may be further inflated and worked after removal from the mold.  The molds used are made of a two or three parts or the simple one part dip or optic type.


The following examples illustrate glass objects which are made by mold-blowing from the Allaire Collection and others.  Click on the photo to enlarge.

 Date: 4th. century AD  Isings form: 124B  Size: ↑ 12.4 cm | Ø body: 5.81 cm | Ø Mouth : 4.15 x 4.71 cm | Ø Base facet: 3.41cm| Weight: 69 g  |


Technique: Free blown Jug, tubular foot ring applied. Handle and trail around neck and under the mouth applied. Mouth tooled to a trefoil shape.

Description: Late Roman glass jug of the Constantinian era in translucent white and middle-green colour, with globular-ovoid body, cylindrical neck and trefoil mouth, green tubular ring base with pontil mark. Handle applied on shoulder, drawn up and attached to the edge of the rim in a fold. Green trail wound around neck and below the trefoil mouth.

Condition: In fair condition, several stable cracks to the body. Trail around the neck halfway broken off.

Remarks: Lots of adhering sand partly mixed with possibly its original content, for the glass of the body and neck are no longer translucent. There is an irregular contrast to the white semi-transluscent body and the green-coloured neck, as if the technical skill to separate the colours has failed.

Provenance: From a private Dutch collection, previously unpublished. No specific data of provenance known.

During the making of vessels, blobs of molten glass were dropped onto the surface creating a raised decoration, sometimes called prunts.  It was an option for the glassmaker to leave the blobs in an irregular smooth shape or to form a pattern such as a lion head or a raspberry design as with the German roemers.   On others the hot glass blobs were pulled out with a tool forming spikes.  The texture of these prunts provided a  firm grip on the vessel, as diners during the Middle Ages may have been eating with their fingers.

The following pictures show examples from our collection to illustrate various styles of blob decoration.

of Hans van Rossum

First half of 4th century AD | Eastern Mediterranean, Syria

 Size↑9.7 cm | ø 6.6 cm | Weight 76 g

Technique:Free blown, pinched ribs and toes; coil applied

Description: Transparent pale amber glass, squat globular body with five vertical ribs, made by pinching and topped by tooled knobs. Base with five similar pinched glass ‘toes’, no pontil mark. A broad splayed lip with in-folded rim, beneath with a turquoise transparent trail of glass which was added as a highlight. Like all sprinkler flasks this specimen has a tooled diaphragm with a hole at the base of the neck.

Condition: Intact and clear, perfect condition

Remarks: The pinched ribs and small ring of pinched toes forming the base of these vessels evoke pomegranates, visible by turning them. The popularity of pomegranate-shaped sprinklers may have been inspired by the fruit’s symbolic associations with beauty and fertility.
