Bonnie Kemske, an expert on ceramics and tea bowls and author of "The Teabowl: East and West," regards some of these contemporary bowls highly.
Indeed, contemporary Western takes on tea bowls should be seen as a "separate genre" to their Japanese counterparts, she argues.
He said, "I have always thought it laughable that Western ceramicists should want to make (Japanese) tea bowls -- functional items that are firmly rooted within Japanese culture.
"If they are inspired to make contemporary versions, they should research the tea ceremony and understand the cultural importance of the traditional tea bowl," she said.
Harrison, who has studied the tea ceremony, has created a range of porcelain tea bowls adorned with 16th century images of the River Thames.
