107E Venetian Filigrana Glass Vase of the Allaire Collection of Glass

107E Venetian Filigrana VaseH: 12.7 Date: 1700 Venice

Description: The pear-shaped body of this Venetian vase is fashioned with two styles of filigrana retortoli canes. The straight neck may have had a lid.  The vessel is decorated with clear glass wing handles, single center trail and ring foot also of clear glass.  The dating of this vase is based on a similar object in the collection in the Rosenborg Castle in Copenhagen.

Remarks: In 1709, the Signoria in Venice gifted filigrana glasses to the Danish king, Frederick IV for his castle at Rosenborg. Now referred to as Rosenborg-type glasses, these were technically different from earlier Venetian filigrana glasses made with two layers, or more specifically: a layer of canes on an inner layer of cristallo. With the exception of very large examples, the Rosenborg-type filigrana glasses, are made of a single layer of glass canes using a technique called filigrana a retortoli.

57A American Green Glass Pitcher, “Juno’s pitcher”

from the Allaire Collection of Glass

Juno's pitcher

Height: 5 1/2 inches Date: Early 19th Century, South Jersey or New York State


Description: Free blown pitcher of natural colored green glass with tooling around a trefoil shaped rim and applied handle. The handle of this pitcher where applied from the rim down to body unlike Roman glass vessels in which handles where generally applied from the body up to the rim. The aesthetics of this object are wonderful for a simple early pitcher.

Remarks: All of the very early American glass companies 1608-1783 were opposed strongly by the British, and after a few years they failed. It was not until the end of the Revolutionary War in 1783, followed by the second war with Britain in 1812-1815 together with the trade embargo on British goods, that American glass manufacture really took off. Glass-making in America increased during every decade of the 19th century. In the 1820s, the American invention of how to make pressed glass made tableware affordable to middle-class households.  As the American industry and prosperity increased in the mid-1800s, a taste developed for ornate styles and complex decorations. It is very difficult if not impossible to find America glass made here before the year 1783.  Most of this glass of that period was imported from Europe.  Our interest in collecting early American glass falls in a very narrow range of years of manufacture, 1783 to 1850.  We also collect only free or mold blown vessels. When visiting glass shows in the United States the dealers will often have some European objects mixed in with the American glass and sometimes even an occasional Roman vessel.  It was these finds of European glass that got us started with collecting European glass.

Remarks II: Juno’s pitcher is the name we gave this object because we found it at a glass show and bought it on the same day our dog Juno died.

26R Core-formed Alabastron from the Allaire Collection of Glass

                         Date: 6th -4th Century B.C. Height: 9.6 cm Weight: 49 g

Description: This vessel was manufactured around 6th to 4th Century B.C. using the core-formed method of glassmaking. The shape of this Alabastron was inspired by the common Greek pottery of the period, a form frequently used in core glass. The decoration is also typical using trailed and marveled threads of yellow, turquoise and red.  Glass objects from pre-Hellenistic periods were luxury items, affordable by only the upper class.

Technique: Core-formed; applied rim-disk and handles; zigzag pattern of applied threads caused by the tooling and marvering.

Condition: Intact

Parallels: In the book, Ancient and Islamic Glass, Paris, Loudmer, Kevorkian #327 & 331, The Constable Maxwell Collection #15, The Yale University Art Gallery #23 & 24, Glaser der Antike, Sammlung Erwin Oppenlander, Axel von Saldern #165 (Now in J. Paul Getty Museum at the Getty Villa).

Remark: Methods of making glass objects came about shortly after natural glass was discovered.  The first glass objects manufactured were not vessels but amulets or pendants and beads. Using the technique of rod forming, tooling and applied elements.  Vessels were made later by core winding from 1500 to 1200 BC. in the Mesopotamia, Egypt and Eastern Mediterranean region.  Production declined between 1200 and 800 but revived from 800 to the 1st century BC. After the introduction of glass blowing by the Syrians 100 BC, the method ceased to be used with few exceptions.  A good scholarly book on this type of glass is Early Ancient Glass, David Grose, Toledo Museum, 1989.

Blown Ribbed Glass Bowls with Delicate Trailing

Blown ribbed bowls (Zarte Rippenschale) with the ribbing ending at an arc under the mouth were decorated with a delicate filament of applied glass trail spiraling around the ribs. This relatively small group of vessels was circulated primarily in northern Italy, the Upper Adriatic, Switzerland and the Rhineland and maybe a Western product, date-able  to the first century and possibly later. The bowl was made by mold blowing, followed by working free-hand to apply the trailing, expanded by free blowing and finished with working the rim. This type of vessel was also made without the trailing decoration. The examples of both types are shown from many museums and private collections.

01R SPRINKLER FLASK (our first Roman glass vessel)

Date: 3rd to 4th Century  Size: Height: 7.5 cm Rim: 5.2 cm Weight: 51.5 g


Remarks: 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.

Glass 5000 Years, Edited Hugh Tait, New York 1991 Date: 1st century BC


Vetro a reticello Filigrana is literally, glass with small network. It is a type of glass decorated or made with opaque white or colored threads of glass, embedded in clear glass which are called canes.  Originally used to make early Roman cast bowls of the first century BC and reinvented and greatly refined in Murano in the sixteenth, seventeen, and early eighteenth centuries. It was only in the nineteenth century that colored Filigrana became popular again.

This is a link to a Corning Museum Of Glass clip by Bill Gudenrath on how RETICELLO GLASS VESSELS are made.

This is a second link to an earlier feature posted on this site entitled WONDERFUL GLASS CANES.  It shows how canes are created and then used to decorate glass vessels.



Date: 1st century BC



Date: 16th -17th century
