Concentric manufacturing ripples are visible on the interior base, characteristic of pressed glass techniques. The underside features an embossed maker mark consisting of a central crown symbol partially encircled by the letters PYREX. This mark identifies the piece as the work of James A. Jobling & Co. Ltd.
