going back some years there were a variety of chats on the Board about the British glass maker Hailwood & Ackroyd, plus there's some information on the history of the company on Grace's Guide - but of late posts for this stuff are noticeable by their absence.
In view of the nature of their business, most information available concerns glass relating to lighting, pressed glass, advertising material, and their 1930s decorative coloured wares - see Hajdamach - and very attractive pieces they are. References to cut glass items are almost non existent.
See also Nigel Benson's internet article where he discusses his research into their manufacturing output.
Some time in 1930s, the company created the trademark name of 'Hailware' - and most of the coloured art glass material appears to be so marked, though IIRC differently to the bowl here. On this bowl the backstamp looks to be acid marked in freehand, so not entirely sure how this was done - through a resist perhaps - but definitely not the usual upper case mechanically blocked style, and as to date of manufacture I'd suggest 1940s but that's a bit of guessing. The bowl is almost entirely without wear, so perhaps been in Granny's cabinet for some time.
Cutting on this piece is hardly avantgarde - cross cut relief diamonds, four-way fan splits, deepish mitres and scalloping around the rim. Of course there's no guarantee that the Company did inhouse cutting work - they may have done - but lack of available information makes it difficult to be certain that they both made and decorated their cut glass, of which there appears to be very little around.
Height of bowl is about three inches - diameter five inches. I've had this for some little while but it was tucked away and only discovered today - I thought originally it was a finger bowl - it might be - but the scalloped rim is perhaps unusual for a finger bowl?
Is anyone able to add more information about 'Hailware' cut glass - or put me right on any errors above - thanks for looking
