Any ideas who made this lovely little crystal bowl please? Very thick walled and heavily textured both on the outside and inside, apart from its flat polished rim. 4.5" diameter and quite heavy weighing over 1 kg. Previously used as an ashtray, which isn't ideal, since the inside is really bumpy and textured, so was difficult to clean.
I've searched through virtually every Scandinavian glassworks that I can think of without success but it might not of course be Scandinavian and I'm searching in the wrong direction. A little bit similar to Tapio Wirkkala's "Lunaria" range for Iittala, but they appear to have a thinner wall and narrower rim, plus the base is different, this one having a small area of smooth glass.
TIA
