Norgesglass

When I talked to my mother about her
tyttebærsyltetøy, she warmly recommended
preserving the jam in a glass jar called
Norgesglass.

Norgesglass were, according to the
Norwegian Wikipedia, produced in Norway
from 1908 to 1978, in a staggering number
of around 75 million jars.
Even dividing that number by the presentday
population of Norway gives you around
15 - 16 jars per person!

Despite the fact that Norge (Norway) is clearly
written on each jar, the invention actually
came from Yorkshire where John Kilner & Co
Glass Company invented and produced
such jars from 1842 to 1937.

But other countries and producers copied
the idea, and as already mentioned, it was
produced in Norway for seventy years.
For the last twenty years (1958-1978)
it was produced at Moss Glassverk,
a glass factory that has now become
a residential area of Moss.

There are at least six different sizes of
Norgesglass.

You can still find Norgesglass at the local
fleamarkets and at charity sales.

In general , the number of Norwegians
picking berries and mushrooms,
and preserving meat etc.
has gone down drastically, in particular
after the fridge and the freezer became a
common household appliance.

The glass jars can last for a long time,
if they don't break, but there is usually
one part you to buy new, namely
the rubber rings.
