This small Blue and Green Bowl as well as the lid and handle were made from Blue and Green Cane.
Cane is made using a special kind of kiln called a Vitrigraph. Glass is arranged in a container in the Vitrigraph kiln in a way that will create the intended pattern in the Cane, then when it gets hot enough to be molten, I draw the glass from the bottom of the kiln in the form of long rods that are about 1/4″ to 3/8″ diameter. As I draw the cane from the Vitrigraph kiln, I turn it back and forth to make the colors in the pattern spiral around one another like vines.
Once the canes are cooled, they are cut to length, then fused together to form a sheet which is again cut into pieces that are fused together to form a round disk. There is a lot of precision cutting and grinding required to make the pieces all fit together tightly and create the Radiant pattern where all of the vines in the cane seem to Radiate from the center. For this piece, one disk was made for the bowl and another for the lid.
The bowl shape was created using a kiln process called Drop Ring. This is a kiln procedure in which a thick disk of glass, which in this case is the Radiant disk described above, 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. In this piece, you can see how the cane was stretched to form the sides of the bowl. 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..
This bowl would make a good candy dish, a container for precious items or just a beautiful decoration to admire.
