Stained Glass #4

Flashed glass Architectural glass must be at least 1/8 of an inch thick to survive the push and pull of typical wind loads. However, in the creation of red glass, the colouring ingredients must be of a certain concentration, or the colour will not develop. This results in a colour so intense that at the thickness of 1/8 inch, the red glass transmits little light and appears black. The method employed 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, that is then blown into a sheet of laminated glass using either the cylinder (muff) or the crown technique described above. Once this solution was found for making red glass, other colours were also made this way as well. A great advantage is that the double-layered glass can be engraved or abraded to reveal the clear or tinted glass below. The method allows rich detailing and patterns to be achieved without needing to add more lead-lines, giving artists greater freedom in their designs. A number of artists have embraced the possibilities flashed glass gives them. For instance, 16th-century heraldic windows relied heavily on a variety of flashed colours for their intricate crests and creatures. In the medieval period the glass was "abraded" (ground off); later, hydrofluoric acid was used to remove the flash in a chemical reaction (a very dangerous technique), and in the 19th century sandblasting started to be used for this purpose.

I don't think of myself as a role model. I do try to live in a compassionate, considerate and positive way. The only advice I can offer is to find what you love to do, find the joy in it, and express yourself through your passion.
