The glasses I used for these two 46 x 13 cm bowls are without a doubt one of them.
For the colored bowl I treated myself to a few beautiful pieces of Bullseye transparent colored iridescent coated glass.
The bowl, which is essentially clear glass, lives on the narrow strips of dichroic. Depending on the incidence of light, the angle of view and the background, both bowls always look very different - that makes for an additional charm.
