This bowl was created by first making a sheet of glass using strips of multiple different shades of transparent Green glass alternating with white strips. After the strips had been fused into a solid sheet, the sheet was cut into triangles which were then arranged to form concentric squares, and then fused together again to make a disk for use with a kiln process called Drop Ring.
Drop Ring is a kiln procedure in which a thick disk of glass is placed on top of a flat mold that has a large opening in the center. That mold is raised on posts inside the kiln so that it and the glass disk on top of it are raised several inches above the kiln floor. As the glass disk is heated in the kiln, it eventually becomes soft enough that the portion of it over the hole in the mold starts to sink down through the hole. As it does so, the glass from the disk stretches into a bowl shape. When the glass stretches out far enough to reach the bottom of the kiln, it flattens out to form a flat bottom on the bowl. At this point, I open the kiln to rapidly cool the glass to the point where it will stop moving, then close it again to allow the glass to continue cooling and anneal in a controlled fashion so it will be strong.
After the glass has cooled to room temperature, it is removed from the mold, but there is still a portion of the original disk attached at the top of the bowl which I call the collar. The collar is cut off using a Wet Tile Saw, then I grind and polish the rim where the collar was removed to remove the saw marks and return it to a pristine surface.
The dark Green used in this bowl is Aventurine which really sparkles when the light hits it. The different photos show the effects of different lighting on this bowl and the beautiful shadows that it casts when lit from above.
This bowl would make a good candy dish, a holder for precious items or just a beautiful decoration to admire.
