Storehouses of parchment

[Aga Tentakulus]

It is a technical problem as well, not a question of price only, printing ink is based on oil and does not work well on parchment.

Another issue is the predilection of Italy for using  parchment, while Germany preferred paper for reasons we do not know, there was an extensive trade and this is one of the reasons  why I think the ms. was written in Italy

It could be because parchment was also used as a building material in the north. Parchment soaked in wax or oil and stretched on a wooden frame. It was used as a kind of window glass. Lets light in but wind out. So to speak window glass of the poor man.

This was once mentioned in the construction of Guédelon Castle in France.
