This bottle is an old soda bottle. It has a really nice shape and I like the cap that's attatched to the bottle neck. It's made of porcelain and is somewhat different from today's plastic bottle caps... The name of the brewery (Hansa) is printed on the cap. This is a brewery in Bergen which is situated on the west coast in the south of Norway.
This kind of bottle is an old milk bottle. At first they where transparent and then they changed to this type of brown bottle, before they completely abandoned glass bottles and started using cartons. I think this happened before or around the 1960s because I'm born in the 1960s and don't remember the glass bottles.
