I am now seriously confused. I went to the "Loch Heather & Peat" exhibition just about 4 weeks ago (it's on in Perth), and there I saw a jug, some glasses and a decanter which were clearly labelled "Stroma". I was very interested to find out the name, as I have a Stroma jug - a piece I got a long time ago, not having a clue what it might be, just that it reeked quality and good design.
Stroma, according to my memory of the exhiition, and my handling of my own piece, came in two colours - one bluish, the other more browny - but both very dark smoky colours - the blue is darker than this rose bowl.
Also, in the Stroma range, the glass is unusually (for Caithness) thin
, possibly may even be soda glass.
So I am of the opinion that Stroma is earlier than this rose bowl design, I do not see much Stroma about, and I see these rose bowls absolutely everywhere. I do not think this rose bowl is Stroma.
Wrong colour, wrong design, wrong glass, wrong period.
(I might be wrong, though!)
