A very small amount of whitefriars glass was ever permanently marked.
The Studio Range of 1969 designed by Peter Wheeler were the only regularly marked examples of Whitefriars, these items were produced for less than a year and engraved with Whitefriars, the pattern number and date.
Whitefriars did not acid etch mark the base of their glass.
There have been many labels used by Whitefriars over the years. Originally James Powell & Sons of London 1834 had no marks or labels .
1. They started using the paper label from 1870 to 1923 it was a round old works label with 'POWELL WHITEFRIARS GLASS WORKS'

4. From 1950 approx to 1963 a paper label with a friar 'WHITEFRIARS CRYSTAL MADE IN ENGLAND'
5. From 1963 to 1979 a paper label in the new graphic style with a styalised friar 'WHITEFRIARS HAND-MADE CRYSTAL' by this time the company had changed its name to Whitefriars Glass Ltd .
