This is a familiar art work design of tulips. Tulips are originally from Turkey and this tulip design has become a symbol on many things. You can see it very often on porcelain things or even at buildings.
Raku Ceramic from Japan is here combined with tradition and symbolism of the Ottoman Empire: a kaftan decorated with a tulip, Turkish symbol of beauty, perfection and God. Raku has a rich metallic glaze with an unpredictable crackled effect.
