19R Blown Ribbed Bowl First C. AD H: 6 cm, D: 8 cm

19R Blown Ribbed Bowl First C. AD H: 6 cm, D: 8 cm

19R Roman Ribbed Glass Bowl from Allaire collection

The early cast ribbed bowls of the Hellenistic Period were simulated in the First Century by blown bowls with pinched ribs.  This example is made of clear colorless glass with no decoration and seems to be rarer than the colored decorated bowls of this type.  It was probably made in Northern Italy.

This pale olive green bottle has a funnel-shaped mouth and two handles of a darker green color. The faint diagonal pattern on the body was achieved by first blowing the glass into an optic mold. The bubble was then removed, twisted and further inflated. The small hole created by the neck constriction in this vessel permits only a drop or two of liquid to pass through at a time. This also prevents the costly contents from evaporating. The glass is still fairly clear and transparent as it was originally intended when created. Flask is intact. It was found in Israel.

The Tuscany region of central Italy has been a glass manufacturing center since Roman times through the Renaissance up to modern day.  The glass made there in the 15th to 17th had a slightly different styling than glass from Venice in the Veneto region of Northern Italy.  The examples in this post will illustrate this.

The Roemers and Berkemeyers shown in this post all have stems decorated with smooth spherical prunts.  A prunt is a blob of glass applied to a glass object mostly on the stem.  Usually these prunts have bumps (called raspberry prunts) or have pulled spikes coming out of the center of the prunt.  Smooth spherical prunts on vessels are rarer.

The Berkemeyers were the forerunners of the Roemers.  Made in the 15th C. as short beakers they had a conical shaped bowl attached to an open stem decorated with pulled drops or prunts.

Roemer (Dutch) or Römer (German) is a type of wine or beer glass that evolved in the Rhineland and the Netherlands from the 17th Century.  They have their roots in the Waldglas (Forest glass) particularly the Berkemeyer, Krautstrunk and Nuppenbecher of the later Middle Ages which were produced in northern Germany, the Low Countries and central Europe.  The Roemer style glass is still being produced today.

The Dorflinger Factory Museum

The museum is located in beautiful White Mills Pennsylvania. The Museum is in renovated buildings which were part of the old Dorflinger Glas Works and in the Dorflinger-Suydam Wildlife Sanctuary. This link is to their website:

The glass collection is one of the Nation’s largest collection of American brilliant-cut Dorflinger glass displayed in the home of the founder.  It is more than 1,000 pieces of cut, engraved, etched, gilded and enameled crystal.

Beginning in the 1860s, Christian Dorflinger transformed White Mills from a sleepy hamlet on the banks of the Lackawaxen River into a bustling industrial center. For more than half a century the Dorflinger Glas Works produced exquisite cut lead crystal that graced many of America’s finest tables, including those of several White House administrations.

The museum is arranged so that it tells the story of how these glasses were made and shows how it was used in a beautiful period room. Below are pictures of the museum and the some of examples of the fine glass collection.


There are two Dorflinger museums in White Mills – the Dorflinger Glass Museum in the grey farmhouse (pictured below) where the family first lived when they came to White Mills, and the Dorflinger Factory Museum (above) in the old factory buildings.  The Dorflinger Glass Museum website is

Roman glass simpulum From The Windmill Collection of Roman Glass

Date: 1st – early 2nd  Century A.D. ,  Adriatic Sea area Size: H =  7.4 → 10.0  cm, D = 5.7 c

Condition: completely intact

Classsification: Höricht 1995, form 17

Description: Translucent blue green free-blown glass. The wall of the body runs slightly bent from the folded edge to the applied foot, slightly welling up in the middle of the bottom. There is no pontil mark. The separately applied handle, fluttering wider on one side on the edge, initially runs straight up. From approx. 7 cm nodded twice and then with a bend culminating in a narrower end.

Remarks: Glass simpula or serving spoons are rare. The few glass ladles known from the literature all have an upright grip. The shape of the handle of this one is fairly unique, because the glass blower has, with a number of curves, ensured that this simpulum can also be hung up.  The glass serving spoon is derived from bronze and silver examples, probably mainly made in the Pompeii area. Like the bronze one in the House of Menander and the silver simpulum in the Casa di Lucius Habonius Primus, both with an inward-facing end of the handle for hanging. The dimensions of the glass serving spoons are generally considerably smaller than those of the bronze and silver ones.

Simpula were also depicted on the coins of Roman Emperors in the 1st and 2nd centuries AD. As one of the seven priest attributes of the Emperor in his function as Pontifex Maximus. Special is also a picture on a bronze coin of Empress Lucilla Augusta (163-189 AD) where on the other side is Vesta, Goddess of hearth, home and family, near an altar with a simpulum and a palladium in her hand. The Vestal Virgins lived together in a house near the Forum (Atrium Vestae), supervised by the Pontifex Maximus.

Date: First century AD. Western Empire, probably Italian, Campania.


Size: Each beaker: H: 13.0 cm. D: rim: 7.0 cm. D: base: 4.8 cm. Weight: 90 gr.

Condition: (L) Two cracks at  the rim and one at the inner lower body. Fine bluish silver iridescence. (R) Tiny chip to the rim. Fine golden green iridescence.

Technique: Blown into three-part mold: two vertical parts and a third part for the disc shaped base.

Description: Transparent yellowish green glass. Downwards tapering cylindrical body, decorated with eight vertical ellipse formed indentations, framed by parallel raised ridges and separated by vertical rows of dots and dimples, connected at the bottom side by festoon formed ridges. Rim cracked off and ground. Slightly concave base with two raised concentric circles around central boss. Horizontal raised concentric circle around the body 7 mm above base. No pontil mark.

Remarks: (1) Only two parallels of this type of beaker are known: one in Naples (from Pompei) and one in the Cologne Museum. This set of two identical beakers is unique. (2) Both beakers have the same height, diameter, weight and decoration. Most probably they were blown in the same mold by the same glassmaker. Also the parallels in Naples and Cologne have the same height and decoration, which may justify the assumption that there was only one workshop that made all four beakers. (3) These beakers may be compared with similar beakers with different ornaments, such as a “Lotus-bud beaker” (NFB 168) and a “Mythological beaker” (NFB 260). All of them have truncated conical bodies with cracked-off rims and can be classified as Isings form 31 or closely related.

Provenance: David and Jenny Giles Collection, London, UK. Sasson Collection, Jerusalem, Israel.

The master-glassmaker Ennion worked from about A.D. 30-70. His signature is known from fifty to fifty five surviving pieces, and many other works are attributed to him on the basis of style. He reportedly created the technique of mold-blowing glass vessels. Mold blowing: Inflating a parison of hot glass in a mold. The glass is forced against the inner surfaces of the mold and assumes its shape, together with any decoration that it bears. This new process allowed the vessel to be decorated as it was formed and permitted the creation of multiple copies of the same vessel. Ennion’s clear, precise designs distinguish his work; he also minimized the visibility of the lines caused by the seams in the mold.  Sometimes Ennion’s marketing genius is overlooked for he was one of the first artists to develop a brand name, “Ennion Made Me”.  The location of Ennion’s workshop is debated, in part because his work is found throughout the Roman Empire. Some scholars believe he worked in Sidon located in modern Lebanon, and later moved to northern Italy. The inscriptions he frequently used as decoration may provide a clue. Though his name may have been Semitic in origin, he signed it in Greek, the language of the eastern Mediterranean, not Italy. The city of Sidon, where he may have worked, had all the raw material for glass-making and extensive trade connections.  The Metropolitan Museum of Art and Corning Museum of Glass both had an exhibition on Ennion’s Roman glass 2015.  This was a fascinating show.  All these great works of glass in one place.

A comment was made by Hans van Rossum and Theo Zandbergen; that Ennion may have been a master mold-maker….so he made these amazing molds and put his name on it…and his workers were the glass blowers.  The title of this post should be: ENNION MASTER MOLD-MAKER IN ROMAN TIMES

The exhibition catalog: Ennion Master of Roman Glass is still available at this link. This book about the Glass master Ennion and the products he could blow in the first century AD.
