This hand blown glass spiral bowl measures 7 inches wide and 3.75 inches tall.
This hand-blown glass bowl was created by first rolling a molten clear bubble through a layer of colored aqua glass chunks that are about the size of rock salt and then rolling it though similar sized colored powdered glass. The next step is to blow the bubble into a aluminum optic mold that has 12 triangular ribs on the inside of it. The ribbed bubble is heated and twisted to create the vortex 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.
