I have been puzzled by certain vases, which have appeared over the years, which have finishes that are not typical of Inwald production, particularly as the moulds were transferred in the 1980s. I have major reservations about black glass, for example, not a colour of glass traditionally associated with Rudolfova hut' vase production, but definitely a colour used by Rosice. Though not a pre-war specialist, my research into the work of Rudolf Schrötter has meant taking a much greater interest in the Barolac items.
