Topic: Easter riddle - guess the maker!

[dirk.]

This one seems to have the right shape for an Easter riddle.
It´s made of an almost black amberish brown, heavily cased with controlled bubbles between
the layers and a tiny opening. Anyone hazard a guess???
It´s ca. 14cm tall and weighs almost exactly 2kg.

I´ll give one or another clue later...

Perlora, Hineri, Rigoleau?

[dirk.]

Nope, so far. Not scandinavian, Perlora, Hineri or Rigoleau. (I must admit I haven´t heard of
the latter and consulted ´glass fact file a-z´ by I. Haanstra. Do you mean ´Rigolleau´of
Argentina?)

I hadn´t expected to get this far without the usual question ´Can we see a picture of the base?´.
For dramatic reasons I reserved it for later. Is  a clue or does it confuse things further?

The base is perfectly concave, ground and polished, with the slightest 1mm ground ring.
