William Morris wallpaper design (arts & crafts movement)! It so beautiful! I do not know the author of this picture is, but I chose it because I think it is relevant to understand the content I'm looking for!
Now THIS is stained glass, because the picture is --- in places, at least --- painted onto the pieced of glass. If it were just bits of coloured glass joined with lead strips into forming a picture, that would NOT be stained glass.
Magnificent Art Nouveau glass panel screen consisting of fifteen panels which were removed from a period house in Edinburgh. The colours are fired on to thick 8 mm glass and are therefore impervious to ultra violet light and water. They date from the 1890s and were probably of Viennese manufacture.
