Early Jens Quistgaard for Dansk Flamestone Coffee Pot with Mugs and Demitasses

Denmark ‘Flamestone’ coffee or tea pot, four demitasses, four mugs, and eight saucers (four small / four larger) by Jens H. Quistgaard for Dansk Designs, circa 1958-1964.
Features the Flamestone signature slate, almost brown glazed-earthenware with striated pattern and white porcelain interior (pitcher has a green tinge to the porcelain interior). Elegant, attractive set with only one fleck to the rim of one of the mugs (very minor and easy to miss — see photos for closeups).
Early, Danish production, as indicated by the markings and rough exterior (a smooth version was introduced in 1964).
