This small hand-blown glass bowl has cobalt blue cane that twists around a clear glass bowl. The spiral converges at the center of the bowl, creating a vortex of color.
It measures about 7.5 inches wide and 3 inches high.
This hand-blown glass bowl was created by rolling blue glass rods onto a bubble of molten glass and then twisting the bubble into a spiral. Another layer of molten clear glass is gathered on the bubble and then blown into a sphere. The final move is to put another metal rod on the bottom and brake it off the blow pipe. The bubble is then heated and opened into the bowl with rods of graphite and wet newspaper. When finished, the bowl is placed into a 950 degree oven to cool slowly overnight. Food safe.
