I've seen these in other colours (blue for example), usually sold by German ebay sellers, but unfortunately never attributed. It reminds me slightly of the Hlava or Lipsky pieces, but I don't think its one of them, merely something created in the same sort of technique. It could be German instead of Czech, but anyway I'm hoping someone here knows more.
The pattern is created by cutting or polishing a horizontally ribbed vase (the ribs can be felt more clearly on the inside).
19.5 cm high, 6 cm across. The rim is polished flat, and the base is also polished without marks.
