The technique of blowing glass within a mold enabled glassmakers to create vessels decorated with designs or inscriptions in low relief. The inscription on this piece is incomplete, but comparisons with similar vessels suggest that it may have been meant as a cross followed by a request to pray for the maker or owner of the glass.
Inscription: Inscription: (on side) F O (backwards R) E ; mark (on bottom) cross with offset cross (See attached scans of handwritten Catalogue Cards for further information).
