Nittsjö Keramik

Nittsjö Keramik is a Swedish pottery that was started in 1843 as a brick manufacturer.  Today they produce dishes and serving pieces, as well as holiday decorations (Rolf Berg has provided some tomte-themed designs). The Nittsjö website is in Swedish, but it gives a good overview of its products.  They seem to change designs often, and I believe this is older (1980s or '90s).  We have a few of their bowls, and they are sturdy and heavy.

This small bowl was an eBay find.  The bottom is marked with the company name, Sweden, and a shape or design number.
