Lajvardina wares derive their name from lajvard which is Persian for lapis lazuli. These distinctive wares were a continuation of the earlier minai technique and are described in Abu'l Qasim's treatise. The only dated example is a tile formerly in Richard Ettinghausen's collection with the date 1315.  A similar faceted lajvardina decorated jug is found in the Barlow Collection in the Ashmolean Museum, see Fehérvári 1973, no.132, pl.57.
