I presume this is an open sugar, but I'm puzzled as to where it originates or how old it is. It's very nice quality.
I think it's moulded, as there are seams under the handles on the outside. The inside, however as been rounded off, as there are no seams to be felt and no hexagonal shaping, just gentle undulations.
The glass is quite thick: 0.4 cm at its thinnest and about 1.5 cm on the points at the bottom ridge. The base has a pressed 36 pt star. It appears to have had some fire polishing - there are no seams to be felt on the top of the handles, just small indentations.
It's heavy 460g and measures 14 cm handle to handle, 7.5 cm across the bowl and 7.5 cm tall. There's wear on the base but no damage. The glass is what I call 'bright', no coloration.
