Thyssen Stoneware Denmark - Stentoj

These 3 pieces were with some other Danish pottery I bought a while ago. I have been trying to find something about the maker, but apart from there being a lot of Thyseen pottery on Internet sites for sale or auction, I haven't come across any information about the maker/factory.

The first 2 pieces are lovely stoneware oil lamps - I guess for outside in summer for keeping bugs away? They look reasonably recent.  The third piece although it doesn't photograph very well, is a lovely shaped stoneware jug with a beautiful mottled blue glaze and looks to be from the 1960's or 1970's.
