Ah, blue pottery and white flowers. That's as classic as it get. And so striking. Group them together, split them up, place them in front of mirrors or on a mantel. The contrast of blue and white is simply eye catching. I've sees them in both modern and traditional homes, and the effect is always dramatic.
Blue pottery urns and vases at Sanskriti Lifestyle come from kilns in India, like Khurja. I am happy to see our traditional potters adapting their craft to a more contemporary palette. I love the traditional styles and colours of khurja pottery and hope we don't lose it to a chinoiserie fad, but for any craft to survive in this age of machines and mechanisation, the artist must adapt. The Indian version definitely has it's own design elements, where some of the Khurja or Jaipur style that tends to be more Mughal in its influences or just plain intricate, trickles through. Personally I love the blending of these influences.
Original Chinese blue pottery is also abundantly available in stores across India. It comes in a wide variety of quality, but unless you're a connoisseur, it serves the purpose pretty nicely.
I personally have a beautiful 18" urn from a discount store in Seattle and an antique ceramic and bronze combination vase that I bought from a garage sale.
