The first bowl looks like a variant of 'Rhapsody' line by Zemek, perhaps made after Mstisov production was moved to Karlovarske Sklo (Moser) as the colours are a little bright. Here's a a couple of pieces from the same line. I think the last one I show might be from Karlovarske Sklo, although, as ever, I'd defer to Jindrich's opinion.
