There were two wet process bottle kilns making only 50 t/week as late as 1907. This was increased to five? say 125 t/week by 1928. The plant could ship by barge, being close to Bridgwater dock, but also had rail connections and primarily used the latter. The site was cleared, except for some of the later buildings, including a brick kiln, which now form the Bridgwater Brick and Tile Museum. The rest of the site is a light industrial estate.

No rotary kilns were installed.
