Topic: Czech glass vases?

[Paul S.]

quote  .....................…    "The dιcor on these vases does appear to have an art nouveau appearance".      Well, a nod toward nouveau I suppose, but not a design image that originated in that era.   
I should have given my comments a little more thought ………... we've all seen books with end papers, and sometimes outside covers, adorned in what are known as 'marbled patterned papers'  -  feathery/rippled/wavy designs created in liquid form - coloured oils or similar on a water surface, and paper laid thereon which picks up the design.              The craft dated back to the C17, and put simply ………….   a comb is dragged across the surface of the liquid and the teeth create the rippling in the colour - you end up with a sort of zig-zag/wavy pattern as with these vases.
With glass, it's possible the vases here owe something to a second half C19 creative invention known as 'pull-up technique - or similar - there must be people here who will know about such things  -  books are more my thing, not glass  -  perhaps there is something in Charles Hajdamach to help.
Like the vase John.

Pulled decoration goes back to the dawn of glass making, making it over 3000 years old:

The decorative technique must be older than that, I would imagine first used on pottery vessels. Not my area at all but guessing 10,000 years could be possible.

Nothing new under the sun!

            but what do you think John of my suggestion that these vases are examples of that type of decoration - you'd be more likely to know than me if there is a similarity in method of creation

Must be, all rely on a tool being pulled across a surface.
