Selenium, like manganese, can be used in small concentrations to decolorize glass, or in higher concentrations to impart a reddish color, caused by selenium nanoparticles dispersed in glass. It is a very important agent to make pink and red glass. When used together with cadmium sulfide, [9] it yields a brilliant red color known as "Selenium Ruby".
The method employed to create red stained glass is to laminate a thin layer of red glass to a thicker body of glass that is clear or lightly tinted, forming "flashed glass". A lightly coloured molten gather is dipped into a pot of molten red glass, which is then blown into a sheet of laminated glass using either the cylinder (muff) or the crown ...
Maclure grew up in rural Scotland, taking up stained glass later in life. [2] She initially worked with her partner to restore and conserve historic stained glass, and later began creating her own work. [3] Maclure's lightboxes are recognisable for both their technical experimentation and their mix of personal, social and environmental ...
The use of thicker glass produces deeper colour effects than traditional lead came stained-glass, especially when illuminated by bright natural or artificial light. [ 1 ] [ 2 ] The technique achieved prominence in the stained glass literature of the 1950s and 1960s.
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]
Medieval stained glass is the colored and painted glass of medieval Europe from the 10th century to the 16th century. For much of this period stained glass windows were the major pictorial art form, particularly in northern France, Germany and England, where windows tended to be larger than in southern Europe (in Italy, for example, frescos were more common).
Glass can be coloured by adding metal salts or painted and printed with vitreous enamels, leading to its use in stained glass windows and other glass art objects. The refractive , reflective and transmission properties of glass make glass suitable for manufacturing optical lenses , prisms , and optoelectronics materials.
The molten glass was poured into a mold of wood or stone to make a sheet of glass. The texture of the mold material would be picked up by the glass. By the time stained glass was being made, the glassblowing pipe was in common use, so hand-blown (or mouth-blown) sheets were made by the cylinder glass and/or crown glass method.
