This bowl features polka dots in pastel shades of blue, violet and pink.
The bowl shape was created using a kiln process called Drop Ring. This 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. In this case, the glass disk was made by fusing small round nuggets of the various colors onto a sheet of clear glass. 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 bowl, you can see how the round dots stretched out as the bowl was formed. 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 can be used functionally or simply placed in a stand to be admired. When it is lit from above, the polka dots cast a lovely shadow as can be seen in the photo.
