The workshop BELLARI is a Tunisian artistic glassmaking which is specialized in the technique of fusing and thermoforming.
This old technique which took its origin around 1500 BC in Mesopotamia has seen its heyday during the entire Egyptian civilisation.
In early Christian era, the fused glass was replaced by the blow. Hence its disappearance around 500 AD and its revival in the twentieth century.
In his approach, and part of its initial training as an interior designer converted to Fusing, Ishraf Bou Sabbeh focuses on functional art: lighting, tableware, bathroom basins, mirrors, vases , jewelry and glass pendants.
In 1935: They control the colour, the phases of dilation and retraction and lead finally to glass with fusion such as we know it today. About 1940: First artistic achievements, in particular those of Michael and Frances Higgins. Since 1980: The technique of the fusing is widespread almost in the whole world.
In 2005: creation of our workshop in Tunisia and beginning of research. Definition : The “fusionnage” or “fusing” consists in assembling already cut superimposed pieces of glass whose set is carried in an oven at its melting point to form only one homogeneous part. Glass obtained can be thermoformed (with a mould in order to obtain concave or convex forms). Oven being able to go up until 1000°C. are used for this technique.
The difficulty of the fusing consists in controlling the cooking of the parts to avoid the appearance of the tensions in the material. For that, it is necessary to take into account the nature, the dimension of the piece and the thickness of glasses that you amalgamate. The compatibility of glasses: The used glasses must be compatible; for that, they must belong to the same category and have the same dilation coefficient. They are available in various forms: glass leaves, crushed glass of varied granulometry (calcinings), wire of glass (stringers). A more coloured glass overheats more. The temperature of the glasses is thus not identical. The tensions of the glass can be measured with a stressometer.
Current events: A passion animates the young artist Ichraf Bou Sabbeh who exposes in each recess of the gallery ” Imag’ in ” articles with the remarkable design, with translucent colours thanks to the material she uses i.e. glass. Its ingeniousness lays in the control of particular techniques, the fusing and the thermoforming of which she affirms being the only one to control; Its added-value to combine art and utility. http://www.letemps.com.tn/pop_article.php?ID_art=30955
