VENETIAN GLASS PLATE OR PLATTER

Posted in Uncategorized by Allaire Collection of Glass on July 18, 2018

Venetian Plate or Platter of David Giles

Remarks: Venetian plate or platter with gilded decoration. The most interesting feature of this piece is that the decoration or design on the roundel is of Islamic form and was obviously made in Venice for the Islamic market. I hadn’t appreciated this when I bought it but one day an Islamic expert, Carlo Suriano, saw it and spotted this immediately. I also sent images to the Islamic expert Stefano Carboni who confirmed the same opinion.  Dated: early 1500  Diameter: 36cm  See close up of roundel below.

ROMAN GLASS HEAD FLASK

ROMAN GLASS HEAD FLASK

 

Dimensions: Overall H: 19.6 cm, W (head): 7.7 cm; Rim Diam: 5.7 cm; Foot Diam: 6.8 cm;

Date: 300-499 made probably Eastern Mediterranean

Definition: A Roman glass head flask (1st to 4th centuries) is a type of flask having a bowl in the form of a human head and a tall thin neck rising above the center of the head sometimes with a handle extending from the rear of the head to the middle of the neck. They are made by blowing the hot glass into a two-part mold.

Remarks: After the mid-fourth century, glassmaking declined in the Roman Empire. In the east, where the decline was less pronounced, a group of deep blue flasks, pitchers, and lamps with coiled bases was produced. They seem to have been made in a single workshop, but examples have been found as far afield as the Sudan and South Korea. One member of the group is this head flask, which was blown in a two-part mold. The handle was applied to the neck, drawn out and down, and attached to the head. The remaining glass was dragged down to the neck and notched. The thumb-rest at the apex of the handle was made by pinching the hot glass with pincers.

Comment: Only four head flasks are known to exist made from this mold.  Two are at the J. Paul Getty Museum in Malibu (both shown) and the forth is at the Antikenmuseum in Berlin.  The Corning flask (shown) once belonged to the celebrated operatic tenor Enrico Caruso. The example below from the Boston Museum of Fine Art is a similar flask although not a head flask.  It features a theatrical mask medallion.  The styling of this vessel however suggest it may have been made in the same work shop as the head flasks.

EXAMPLES OF HIGHLY IRIDESCENT ANCIENT GLASS

Posted in Uncategorized by Allaire Collection of Glass on July 5, 2018

WHAT IS THE IRIDESCENCE ON ANCIENT GLASS?

The iridescence on ancient glass was unintentional unlike what is found on modern Tiffany, Loetz, and Steuben glass. Caused by weathering on the surface, the iridescence, and the interplay of lustrous, changing colors, is due to the refraction of light by thin layers of weathered glass. How much a glass object weathers depends mainly on burial conditions and to a lesser extent the chemistry of it. These conditions are humidity, heat and type of soil the glass was buried in. The chemistry of ancient glass though basically the same as our soda glass differed in the purity of raw materials and compositional ratio.  There were also differences in flux alkali used such as natron (sodium carbonate) or potash (potassium carbonate). Generally glass made in the Western Provinces with potash has less iridescence than glass from the Eastern Mediterranean areas using natron. At the same time burial conditions also were different. Natural iridescence is sometimes found on modern glass bottles from digs in the back yards of old houses or pulled out of river beds. The word iridescence comes from Iris, the Greek Goddess of rainbows and refers to rainbow-like colors seen on the glass which changes in different lighting.  It is simply caused by alkali (soluble salt) being leached from the glass by slightly acidic water and then forming fine layers that eventually separate slightly or flake off causing a prism effect on light bouncing off and passing through the surface which reflects light differently, resulting in an iridescent appearance. Modern iridescence sometimes called iris glass is made by adding metallic compounds to the glass or by spraying the surface with stannous chloride or lead chloride and reheating it in a reducing atmosphere.

JULY 4, 1776, INDEPENDENCE DAY

Posted in 1. American Glass, CATEGORIES OF GLASS TYPES ON THIS SITE, Early American Glass before 1850 by Allaire Collection of Glass on July 4, 2018

On July 4, 1776, the thirteen colonies claimed their independence from England, an event which eventually led to the formation of the United States.  What was the most common type of glass bottle in the colonies at that time ?

 

American Chestnut Bottle

Free blown American chestnut bottles were made in great quantities by most of the early glass shops from about 1750 to 1850. They were mostly made of the natural color of glass which is different shades green to brown. The name chestnut is based on the bulbous and flattened shape. The bottles typically are 4 to 9 inches however some are as small as 2 inches and large as demijohns and carboys. Similar chestnut flasks were made in Germany in the 18th-19th century. Ref: Kechum p. 5,11, McKearin Plate 225, Spillman II #45

The three examples from the Allaire collections are:
