Davidson 589/2 style bowls
Gwion James:
Yes, thanks everyone - what's surprising is not so much that other companies might eventually copy it (mine are quite wobbly and approximate in the making) but that Sowerby would have gone straight into production if indeed this was one of the designs Davidson got from the high-profile DRU as part of a modernisation campaign.
Gwion James:
But one tiny point about the supposed ease of copying it, Adam. It would presumably be a little trickier than many designs because one couldn't just take a mould off an existing example - you'd have to calculate the shape of the pre-folded bowl and fabricate a mould from scratch. (I am not sure how the hot glass would have been held for folding either. No pontil, and the round foot is quite differently ground off on each of my two.)
Adam:
Gwion - Re the mould cost, perhaps I should have said "relatively" inexpensive! The point was that this mould could be made almost enirely on a lathe. Dimensions would be no problem - contrary to popular opinion moulds for pressed glass, if to copy an existing article are never cast in some way from the glass. Starting from scratch is the only way.
Re holding the article for re-heating ("melting" in the local vernacular), please see my piece "Unmelted, Melted or Double Melted" in page 6 of the Archives. The 7th para in particular. Then come back to me if you like, about that or anything else.

Adam the pic has gone from Tinypic, can we yobunny it ?
When will yobunny make it into the dictionary
Gwion James:
Thanks, I know little of the techniques - more about casting in metals which I realise is not the same technology.... I only guess that making a mould on any kind of lathe etc. would be easier from an 'undistorted' original. I'll go and consult your text......
