hi - I can see your reasoning for suggesting Timo Sarpaneva - his 'Festivo' textured pieces for example are not too disimilar, although this tumbelr shows a design with lines, and I'm unsure if he produced this particular surface decoration - some of his pieces were in production for a longish time I believe.
The other obvious contender for these ice/bark surface textured pieces would be Tapio Wirkkala for Iittala - but again my books lack adequate catalogue pix, and I can't find this particular design.
Most of the Scandi pieces designs mentioned have simply a random surfact texture, rather than a lined pattern such as yours.
Regret I can't offer other suggestions - we need an expert on Sandi glass

P.S. Just noticed the attractive shade of nail varnish - so might suggest we refrain from calling you Robert?
