This is a highly unusual water tumbler designed by Harry Powell for James Powell & Sons (Whitefriars) at the turn of the 19th to 20th century.
The tumbler is cylindrical with a central waisted portion. It sits on a thickened base which has a central polished pontil. It is made from ‘Sea Green’ glass and has a vertically ribbed effect.
The bowl is also engraved with a delicate undulating shamrock motif that sits just below the rim. This motif can be seen on page 31 of the Lesley Jackson book ‘Whitefriars Glass – The Art of James Powell & Sons.’ Fig. 82 shows a silver-mounted decanter that is attributed to Harry Powell and was shown at The Arts and Crafts Exhibition of 1903.
It has a height of approximately 11.4cm, with a diameter across the rim of about 7.2cm and across the base of about 6.8cm.
It has a liquid capacity (to the brim) of 285ml.
It has an unwrapped weight of 110g.
It is in excellent condition, with no chips or cracks.
