Hi, Is all chalet signed?
One needs to be cautious about unsigned pieces. Peter and I recently discussed a piece, which seems generic. Our conclusion is that these were quite common, and though others may have followed the trend, some of these pieces are Czechoslovakian, some are designed by Frantisek Zemek, some produced by Teplicke Sklo, Mstisov,(formerly Inwald) and later by Karlovarske Sklo Moser. Unlike Moser proper, which I believe always to have been signed, KSM items may merely have had paper labels, long gone.
Czech glass 1945-1990 is, as I am continually finding, an area of surprises.
In Communist era Czechoslovakia, there was a dedicated studio of etched glass, which does not appear in any of the western, English language texts. I found this studio yesterday, but with the exception of one Cz language text, I have never seen any other reference to such a studio. Ostensibly it came under the control of the same organisation that ran Beranek/Skrdlovice.
Regards,
Marcus
