Cutter removing ends of cylinder and slicing the tube lengthwise Sliced tube of glass is flattened in an oven. Cylinder blown sheet is a type of hand-blown window glass. It is created with a similar process to broad sheet, but with the use of larger cylinders. In this manufacturing process glass is blown into a cylindrical shape by a glass blower.
Apsley Pellatt in his book Curiosities of Glass Making was the first to use the term "millefiori", which appeared in the Oxford English Dictionary in 1849; prior to that, the beads were called mosaic beads. While the use of this technique long precedes the term "millefiori", it is now most frequently associated with Venetian glassware. [2] [3]
For example, the cames that make up the matrix of a stained-glass window, for which lead and zinc were most commonly used, undergo quite a bit of thermal expansion and contraction, eventually resulting in metal fatigue, which in turn weakens the joints between the plates, causing whole panels to deform or simply fall apart (Vogel et al. 2007, 8).
Dalle de verre was brought to the UK by Pierre Fourmaintraux [citation needed] who joined James Powell and Sons (later Whitefriars Glass Studio) in 1956 and trained Dom Charles Norris in the technique. Norris was a Benedictine monk of Buckfast Abbey who went on to become arguably the most prolific British proponent of dalle de verre.
Came glasswork includes assembling pieces of cut and possibly painted glass using came sections. The joints where the came meet are soldered to bind the sections. When all of the glass pieces have been put within came and a border put around the entire work, pieces are cemented and supported as needed. [1]
The design can be applied by various techniques, often by reverse painting prior to gilding, or by engraving the design into the gilded layer, or even into the glass. When painting an elaborate design such as a flower, the artist's natural methodology is reversed, with highlights applied first and the background applied last.
The Gennadios medallion in New York, illustrated above, is a fine example of an Alexandrian portrait on blue glass, using a rather more complex technique and naturalistic style than most Roman examples, including painting onto the gold to create shading, and with the Greek inscription showing local dialect features.
Conservation-restoration is the practice of cleaning and discovering the original state of an object, investigating the proper treatments and applying those treatments to restore the object to its original state without permanently altering the object, and then preserving the object to prevent further deterioration for generations to come (Caple, p. 5-6).
