The artistic window is a play of light, colored fragments embedded in a profile of lead. It is a relatively young art compared to other techniques of glass decoration and knows its heyday between 1100 and 1300 with the great Romanesque and Gothic cathedrals.
After a decline period, at the end of the nineteenth century, with the Art Nouveau and Liberty it can be witnessed a revival of stained glass, rediscovered by artists, architects and craftsmen. The artistic avant-gards of the twentieth century explore the expressive power, experimenting with new techniques and making stained glass window a contemporary element.
The “vetro artefatto” craftshop interprets sensitive taste of the client, the architecture and the different techniques of glass art, creating stained glass windows of great beauty. For stained glasses made in this craftshop, only the finest materials are used, hand-blown glass and opal for stained glass, often enriched by grisaille painted inserts and baked at high temperature with oxides and enamels, where the details and figures are more defined. The fused stained glass windows have a contemporary and fresh flavor, the decoration inspired by abstract contemporary paintings make these windows adapted to modern furnishings. The fusing is also appropriate for classic environments with the right decorum. The engravings, also known as sandblasting, are always an elegant choice and have a very sober visual impact, suitable for those who, in their home furniture, do not like the color. In addition, the stained glass windows in mixed techniques but also the tempered or laminated stained glass are created to meet the clients’ new demands.
The lead binding is a technique used for centuries for large windows of churches and cathedrals and for the composition of large stained glass windows. The pieces of glass are edged with lead cames made in order to form the desired patterns on the glass. Also present in the most elegant buildings, the technique of leaded still has an antique flavor that seems to not want to ever go down. With the Art Nouveau and Liberty, the stained glass window has its great revival , developing new shapes and colors. Louis Comfort Tiffany deeply renews the stained glass window from the point of view that technical illustrations , introducing the use of opaque glass, products made by himself, and by replacing the section lead with a ribbon of copper. Currently after a partial decay of the stained glass windows during the second postwar (in which there is primarily concern with restoration), there was a rebirth, with innovations that concern both the formal and the technical, just remember Chagall, Le Corbusier and Anzolo Fuga. After decades of bare and minimalist decor the use of stained glass to decorate houses is rapidly expanding. The individual pieces of glass cut into the required shape for the composition, may contain various processes, such as sandblasting and painting. Special colors are designed to make fade effects and chiaroscuro in addition to the natural transparency of the glass. The more modern interpretation of the leaded glass windows wants the mixed technique as a contemporary interpretation of an ancient art. Often in leaded stain glass windows fit fused glass, engraved decorations in sand, fire and glaze painted details.
The glass fused artistic windows are intended as an expression of an artistic-cultural journey that ranges from painting, to mosaic, to contemporary art, through a unique style and the ability to enhance the brilliance of the materiality of the glass, so that the artistic windows can be the protagonists of unique elegant and refined environments.
With the glass-fusing technique a new glass is constructed, using oxides and enamels to obtain interesting polychrome effects; different hand-crafted bases, can further embellish the windows and objects created with this technique.
Glass fusing is a relatively recent technique to create decorated glass panels, with the thermoformed, it is possible to create panels and three-dimensional objects with reliefs or bas-reliefs, so that the refraction of light gives prominence to the glass artefacts with passages of evocative light.
Glass fusion is an excellent interpreter of contemporary art, an artistic glass fusing window often becomes a luminous framework, a protagonist capable of enhancing any environment.
Variation of the traditional technique, the lead binding, this process was applied by L.C. Tiffany in the late 1800s to create lampshades, decorative objects and the very well known windows. The individual pieces of glass are edged in copper and tin soldering stopped by allowing you to work on curved surfaces. Tiffany through constant experimentation with new techniques reached its peak in the invention of a new type of glass called “Favrile“, which was produced in its furnaces. It was an iridescent glass, which had an infinite range of shades through which you could get some realistic effects never experienced before except through painting. Nowadays the tiffany technique is considered more suitable for making lamps or small stained glass. It is also good to keep in mind that the windows and the objects that are bound to lead or tiffany have a greater resistance than a monolithic glass artifact because of their elasticity, and it is greater when the stained-glass window or lamp is made with numerous pieces of glass.

Sandblasting is a mechanical process that mimics what nature makes on small pieces of polished glass that it is possible to find on the beach. A jet of sand at high pressure affects the surface of the glass making it dull. With the clever use of masks and adjusting the depth of abrasion, sophisticated effects of low relief are created. The sandblasted glass, being a “non-color “, playing on white and transparency, it is a piece of furniture that never bores over time. The decorations that can be made with sandblasting range from the more traditional type Victorian and Art Nouveau to contemporary geometric patterns or up to the landscapes and figurative glass, virtuosity of glass art in which the glass is etched on various plans to get bas-relief rich in details. Today, in addition to the sandblasting of transparent glass, this technique can be made on frosted glass, glass plated or safety glass (tempered glass and accident prevention) so as to meet many different needs. The sandblasted glass windows are always in great demand for windows and doors.
The artistic glass or safety laminated is made from stained glass joined by a plastic to another glass substrate. The tempered glass is obtained by hardening by heat treatment (hardening). Many types of stained fused glass you can also temper (flat fusions). Thus stained glass become six times more resistant than normal glass, and if broken glass fragments do not release dangerous. The sandblasted windows can be either stratified than temperate.
