SQUARE BOTTLE of Hans van Rossum

Mid-1st – 2nd century AD | Northwest provinces of the Roman Empire, probably Italy

Size↑12.0 cm | ø 8.2 cm | Weight 154 g

Technique: Free blown, handle applied

Classification: Isings 1957 form 50a | Fleming 1999 handle typed. MS 5254 | Morin-Jean 1977, form 14

Description: A bottle of transparent bluish-green (blaulichgrün) glass with an almost cubic body, short cylindrical neck, as if sunken into the sloping shoulder. Flaring mouth, rim folded outward and inward. Flat bottom, rest of pontil; massive short two-ribbed strap handle applied on the shoulder and attached to the neck, just below the rim at right angles. No pontil.

Condition: Intact, some weathering

Remark: There are two ways of making these bottles, the mold-blown bottles are the more numerous, others were free blown and flattened by pressure on the sides and the base. The mold-blown bottle is usually of rather thick, bluish-green glass often with a base decorated in relief, the other variety has thinner walls. The free-blown variety mainly occurs in the Mediterranean area’ (Isings 1957). This example is free blown and has a weight of 154 grams. Similar square bottles, but mold-blown, weigh twice. The rim of most specimens is folded inward and pressed flat horizontally. Most handles are two-ribbed, others are three-ribbed or have a lot of sharp ribs, Isings says.Characteristics of a free-blown square bottle: more rounded, in contrast to a mold-blown example which has sharp edges. The neck of a free-blown bottle is mostly sunken into the sloping shoulder, caused by pressing to make the base flattened. No base mark, also a characteristic for a blown square bottle.

Thanksgiving Day is a national holiday celebrated in Canada, the United States, some of the Caribbean islands, and Liberia. It began as a day of giving thanks for the blessing of the harvest and of the preceding year. Similarly named festival holidays occur in Germany and Japan. Although Thanksgiving has historical roots in religious and cultural traditions, it has long been celebrated as a secular holiday as well. It is a day to celebrate and give thanks for health, home, family, friends and good food.

ROMAN GLASS JAR WITH ZIG-ZAG DECORATION of the The Augustinus Collection of Ancient Glass

| From the 3rd-4th century AD. From Karanis, Faiyum*, Egypt | Kisa: Form: F 376.

Size: ↑ 6.82 cm | Ø body: 7 cm | Ø Mouth : 6.25 cm | Ø Base: 4.52cm| Weight: 99 g  |


Technique: Free blown globular jar with concave neck and slightly outsplayed, rounded rim, base indented with pontil mark; applied with trailing between shoulder and rim.

Description: Transparent yellow-green globular jar with rounded rim, short neck, and slightly concave base. A continuous horizontal zig-zag trail, 6 times up and down, forms a ‘collar’ and connects the rim with the shoulder of the vessel. The trail, in exception to most examples, is pushed against the neck. ***

Condition: Complete, zig-zag trail intact; some weathering and with white iridescence, adhering sand; some pitting and bubbles that are horizontally elongated at the rim; many bubbles are typical for the Karanis-glass in the Faiyoum .**

Remarks: * Harden states that there is no reason to suppose this type of glass was made in the Faiyum itself, for no glass-furnace has been found there and suggests these jars were made in Alexandria (1936, p 39).** Whitehouse remarks: ‘Jars of this type, transparent yellowish green glass with purple streaks and many bubbles, are typical of the glass from Karanis in the Faiyoum (CMG II, p 162, no 687).*** A clear, virtually unweathered and very balanced example, with the collar placed very close to the neck, is in the Allaire Collection, (40R Roman Glass Zig-Zag Jar. Link)

Provenance: Most likely from Karanis, Egypt.  From a private Dutch collection. Unpublished before.

COSMETIC FLASK of Nico F. Bijnsdorp

The second half of 4th – 5th century AD. (Syro)Palestinian.

H: 13.0 cm. Dmax: 6.8 cm. Drim: 4.3 cm Dbase: 4.2 cm. Weight: 120 gr.

Condition: Intact. Part of thread on lower body lost.

Technique: Free blown and tooled. Thread, zigzag trail and handles applied.

Description: Transparent natural bluish-green glass with aquamarine thread and zigzag trail. Funnel mouth with everted rim, rounded in flame. Elongated bag-shaped body with constriction just above the hollow, pushed-in tubular base-ring. An aquamarine spiral trail wound counter-clockwise in thirteen revolutions around upper body and neck. On the widest part of the body a thick uninterrupted aquamarine thread wound clockwise as a zigzag with seven legs up- and seven legs downwards. Two coil handles arching up from the upper body and attached to the edge of the rim with an extra fold.

Remarks: It is rather unusual that two threads on the same glass are applied in different directions and there is no explanation why this was done. This type of cosmetic flask (also called kohl tube) was a common product of Syro-Palestinian workshops in the fourth and fifth centuries AD. At the same time or slightly later double and quadruple cosmetic tubes, sometimes with elaborate (basket-shaped) handles were produced in large quantities (see NFB 056), (Live Link NFB 121) and (Live Link NFB 334).

Provenance: Aphrodite Gallery, New York, USA. Private collection Massachusetts, USA, 1970’s.

Dimensions: H = 13,1 cm.; ø bowl 6,8 cm.; ø foot 7,1 cm.’ weight 66 grams.  Origin: Tuscany ~ mid 17th century

Description: The round funnel bowl has 12 ribs formed with the mezza stampaura technique, or the double dip method. In the English nomenclature these ribs are called gadroons. Just above the gadroons the bowl is further decorated with a single thin thread of glass. The bowl is set on a hollow stem embellished with two somewhat annular hollow knobs. Subsequently the stem is set via a kind of “sock” on the slightly conical folded foot. For this type of stem the descriptive term “spool form” was developed. . (See the stem formation chapter on this site).

Remarks:There is a distinctive difference between cristallo and vitrum blanchum (VB). For example, cristallo has much less CaO than VB say ~ 5% vs. 10%. The Na2O% is also different say ~ 17% vs. 13% and for SiO2 ~ 70% and ~ 65% and that can vary by origin. See as example, the Annales of the 20th AIHV congress in 2015, pg. 552, Hulst eo. “The golden age of Amsterdam glass.

Tim Osborne stated in his catalogue of the Tim Udall collection that gadrooning was derived from a continental practice. See the picture of the jelly glass from the Tim Udall collection, now in our collection glass # 109 , which has the same type of decoration. From the input of Peter Korf de Gidts and Kitty Laméris we learned that this type of decoration is typical for glasses from Tuscany. (see the references under parallels)

ROMAN GLASS SIMPULUM of the The Augustinus Collection of Ancient Glass  and co-author  Hans van Rossum

First century AD. | From Aquileia or Adriatic Area |  Höricht forma: 17 |

Size: ↑10.81 cm | ↑Cup: 3.0 cm | ø Cup 7.51 cm | Weight: 38 g|

Technique: Free-blown cup; rim outsplayed, turned down and inward; handle tooled and applied, bent backwards at the top and a small surplus tip folded again; no pontil mark.

Description: Yellow-green, almost white transparant glass; with iridescence and encrustation. Cup mended from 12 parts; handle in one piece; at the end of the handle a smal triangle of glass is folded over as if forming the head of a cobra snake; a very small piece of the tongue or face seems to be broken or cut off.

Condition: Complete and uncleaned, heavy brownish encrustation; the cup once was broken into many pieces, mended in the past and professionally consolidated by Restaura, Heerlen (NL) in 2017.

Remarks:  Excitare fluctus in simpulo. ‘A storm in a teapot’ in translation from the latin, is a reference to the Simpulum in general, probably for the connotation of the instrument as a laddle to tranfer or to stir liquid with.

The true importance of the instrument though is, that it belongs to the seven priestly implements of the Pontifex Maximus. In other words, the Simpulum is a special instrument to be used only by the Emperor or Caesar, from Augustan times on, in his function of Pontifex Maximus, as is proven by coins and other imagery on which the ladle occurs, such as the exceptional beautiful blue and white glass cameo from Cologne, now in the Römisch-Germanisches Museum Cologne, Germany (inv. Nr. 72,153).*See additional information below.

Provenance: From a private dutch collection. Probably from Aquileia, or near the Adriatic coast. Previously unpublished. Rare, several examples are known to be in exsistence.

Ribbing of Glass Vessels


The ribbed design on glass vessels is created by having the glass blower blow a bubble into a mold with internal ribs, sometimes called an optic mold. When removed, the ribs can be left with sharp edges or softened by further inflating, leaving the ribs less pronounced or even extremely faint. The blow pipe may also be twisted and the glass further inflated creating a swirled effect on the vessel giving it the desired surface texture.  The final form of the vessel is then completed.

Below are examples from the Allaire collection and other collectors to illustrate ribbing on glass vessels.
