White Ware or "Vaisselle Blanche", effectively a form of limestone plaster used to make vessels, is the first precursor to clay pottery developed in the Levant that appeared in the 9th millennium BC, during the pre-pottery (aceramic) neolithic period. It is not to be confused with "whiteware", which is both a term in the modern ceramic industry for most finer types of pottery for tableware and similar uses, and a term for specific historical types of earthenware made with clays giving an off-white body when fired.
White Ware was commonly found in PPNB archaeological sites in Syria such as Tell Aswad, Tell Abu Hureyra, Bouqras and El Kowm. Similar sherds were excaveated at Ain Ghazal in northern Jordan. White pozzolanic ware from Tell Ramad and Ras Shamra is considered to be a local imitation of these limestone vessels. It was also evident in the earliest neolithic periods of Byblos, Hashbai, Labweh, Tell Jisr and Tell Neba'a Faour in the Beqaa Valley, Lebanon. It has been noted that this type of pottery was more prevalent and dated earlier in the Beqaa than at Byblos. A mixed form was found at Byblos where the clay was coated in a limestone slip, in both plain and shell combed finishes. The similarities of White Ware and overlapping time periods with later clay firing methods have suggested that Dark Faced Burnished Ware, the first real pottery, came as a development from this limestone prototype.
