As bar tracery opened the way for more complex patterns, masons started applying those same patterns to other surfaces as well as the actual window openings. When used on an otherwise solid walls, such motifs are known as blind tracery, a decorative effect first applied on the west facade of the church of St Nicaise at Reims (1230s).
The pattern is impressed upon the sheet by a printing roller which is brought down upon the glass as it leaves the main rolls while still soft. This glass shows a pattern in high relief. The glass is then annealed in a lehr. The glass used for this purpose is typically whiter in colour than the clear glasses used for other applications.
The millefiori technique involves the production of glass canes or rods, known as murrine, with multicolored patterns which are viewable only from the cut ends of the cane. [2] [9] A murrine rod is heated in a furnace and pulled until thin while still maintaining the cross section's design. It is then cut into beads or discs when cooled.
Hollow glass wall blocks are manufactured as two separate halves and, while the glass is still molten, the two pieces are pressed together and annealed. The resulting glass blocks will have a partial vacuum at the hollow center. Due to the hollow center, wall glass blocks do not have the load-bearing capacity of masonry bricks and therefore are ...
The choice of paint color on the walls in Victorian homes was said to be based on the use of the room. Hallways that were in the entry hall and the stair halls were painted a somber gray so as not to compete with the surrounding rooms. Most people marbleized the walls or the woodwork.
Example of an Egyptian design with wallpaper group p4m. A wallpaper group (or plane symmetry group or plane crystallographic group) is a mathematical classification of a two-dimensional repetitive pattern, based on the symmetries in the pattern. Such patterns occur frequently in architecture and decorative art, especially in textiles, tiles ...
The principal methods of this are enamelled glass, essentially a technique for painting patterns or images, used for both glass vessels and on stained glass, and glass paint, typically in black, and silver stain, giving yellows to oranges on stained glass. All of these are fired in a kiln or furnace to fix them, and can be extremely durable ...
Crackled glass was glass filled with webs of small cracks and fissures, refracting light and causing the glass to have a sparkling effect. [1] Émaux-Bijoux was a technique invented by Emile Gallé. Translucent layers of enamel were built up in layers and then fused to a foil of precious metal, which was then heated and attached to the outside ...
