Crystal glaze is a rare technique seen on some expensive vases, but rarely on snuff bottles.  The results are spectacular but very difficult to achieve, and the yield is low.  This fine artist-created porcelain bottle features attractive royal blue starbursts on a light blue-grey ground.  Very subtle!  And difficult to show in a photograph how beautiful the crystals are!  (White spots are glare from lights.) This classy bottle is dressed up with a fine old Peking Glass or agate stopper
