I've only just begun to read up on mid-century Czech glass, but when I bought this vase recently I knew I'd seen this vertical motif before in Jan Gabrhel's designs. However, I don't know whether he ever designed heavily textured glass of this sort.
The vase has been applied with a thick layer of glass particles, some areas of which are actually pretty abrasive. There are several flecks of some red substance which has seeped between the particles, and which could be ketchup, or could be the blood of a previous owner...
The motif is formed by deep circular indentations roughly 30mm in diameter. The rim is smooth and rounded. The base has been ground to make it level, but left unpolished and with some areas of abrasive particles.
Dimensions: weight is 1047g; height 22cm; diameter 8.2cm.
The front view of the vase makes it look as though it's leaning - it doesn't. And I got the white balance wrong, so the colourless glass looks very grey. I've a lot to learn about this area of photography.
