What makes this particular find quietly remarkable is the technique associated with it. Line-impressed tiles were made by pressing a carved wooden stamp into wet clay to create geometric or foliate patterns, then filling the impression with white clay before firing. The result was an inlaid tile, elegant by the standards of the period, and the presence of a kiln suggests that such tiles were being produced locally rather than imported from further afield.

The kiln came to light during archaeological monitoring on the site of the Dominican Friary at Moneymore, a religious house whose origins place it firmly in the medieval period. The discovery was made under Excavation Licence E0430 and is noted in Campbell's 1987 study of the subject. Dominican friaries were significant centres of religious and civic life in medieval Ireland, and their churches and chapter houses were often furnished with tiled floors of considerable ambition. Finding a production site in the immediate vicinity of such a friary gives a more concrete sense of how those interiors were built and maintained, and how localised the craft could be, rooted in a specific community and its immediate needs rather than in distant workshops.
