I've got a Polish glass bucket, brand name is Portmeirion. The name of the range is Monowave.
It has a Bridget Riley kind of pattern in thin black overlay, acid cut back to thick clear, with a thin white liner.
The rim is polished, no bevels. The clear sections and the inner sides of the black squiggles are quite rough - I can file my nails on them. The black is all smooth and shiny.
I still have the label, it says Made in Poland on the other side. Sorry about the lack of quality of the pics. It is a big thing. Wastepaper basket sized.
