Grimston-Lyles Hill ware or Grimston ware (more recently CB ware) is an Early and Middle Neolithic pottery originally named after the site where it was found in the north east of England, "Hanging Grimston", a long barrow in the former East Riding area of Yorkshire.
[1] In 1974, Isobel Smith expanded this term because she discovered the vessels spread across the British Isles to Lyles Hill in Northern Ireland.
The vessels represent the earliest pottery style of the British Stone Age.
[1] The long-lasting Grimston-Lyles Hill ware is characterized by its use of fine materials, good workmanship and kumpf-like shapes[2] with a shoulder profile and turned-over edge.
A 2018 report from English Heritage used Bayesian analysis to estimate when carinated bowls first appeared in England, and when they ceased to be made.
