Our kitchen lamp had a cheep plastic cord and the ceiling cup was also plastic. A definite no for an old house! My husband changed both the cord and the cup. The fabric cord and the ceramic (rosette) cup are much more suitable for our kitchen.
I found the ceiling cup in a new store Domus Classica (link herje) that opened in Helsinki last Monday. I strongly recommend your visiting there if you have any interest in renovating old houses!
