Window production
In the middle of the 18th century, the dark living rooms began to be replaced by houses with windows. Window glass was imported, but it was a wish that Denmark / Norway should be self-sufficient in window glass.
The two windows above with painted text, come from Soltør Gård in Møre og Romsdal. In 1619 Ole L. Abelset bought this farm, and it is his daughter's name that is painted on one window:
Demoiselle Margreta Ols Daughter Abelset Anno 1714.
On the second window it says: Monsr Niels Hansen Hagerup Anno 1714.

Crown Glass, Table Glass and Green Ordinary Window Glass
Small drinking glasses, apothecary glasses, bottles and probable window glass were produced at Nøstetangen in the first years.
But window production was transferred early to Hurdal (1755-1895).
Bottle and window production were also transferred to Aa's green cabin (1748-1765).
The Weyse catalog mentions a number of gas types and sizes. They made Crown Glass, Table Glass and Green Ordinary Window Glass. Table and window glass were made by blowing large cylinders, cutting them lengthwise, and rolling them flat on a table while hot.
Crown glass was blown like a large barrel and cut into squares after it had cooled down.
In the middle of the disc the glass became thicker, and in the middle there was a punt mark.
This part was called "Gallen".
