My soda glass "Iced Tea" set is a surprise because even the Amber, Green and Darker green items all seem to be the same weight compared to others of their clear ilk. However, I will concede, that without extensive testing via a spectrometer or suitable density measurements others that I presumed to be crystal, in the normal parlance (AKA lead glass), may be ordinary soda glass.
The Pilsner arises from an Ebay advert here - and made a lot of sense as they make lovely beer glasses. Looking at my catalogue I now see the formal title is "Iced Tea".
Still asking the question. Has anyone else found Stuart "Glass" that they know is soda glass, not the normal crystal(AKA lead glass).
