Kvörn

Kvörn is a term with Scandinavian origins, generally referring to a type of mill used for grinding grain. The most common form of kvörn is a hand-operated quern-stone, which consists of two millstones. The lower stone, known as the quern-base or bedstone, is stationary, while the upper stone, called the runner stone, is rotated by hand, typically using a handle. Grain is fed through a hole in the center of the runner stone and is gradually ground into flour as it moves between the two stones.

These hand querns were a staple in households for millennia, particularly in rural and domestic settings where larger watermills or windmills were not readily available or practical. The operation of a kvörn required significant physical effort and was often a time-consuming task. The fineness of the flour produced depended on the design of the stones and the skill of the operator. Different types of kvörn existed, varying in size, material (often granite or basalt), and the pattern of grooves carved into their grinding surfaces, which helped in efficiently breaking down the grain.

While largely superseded by mechanized milling technologies, the kvörn represents an important stage in the history of food processing and agricultural technology. Its simplicity and effectiveness made it a vital tool for food production across many cultures for a very long period. The word "kvörn" itself is etymologically related to words for grinding in other Germanic languages.
