Millstone Wikipedia

Millstones or mill stones are stones used in gristmills, for grinding wheat or other grains.. Millstones come in pairs: a convex stationary base known as the bedstone and a concave runner stone that rotates. The movement of the runner on top of the bedstone creates a “scissoring” action that grinds grain trapped between the stones.

Safety Precautions to Take When Using Naphthalene Balls

Jul 28, 2019 Do not machine dry garments that have a naphthalene ball smell. Air dry them till all the smell is gone and only then start using a dryer. The containers in which the clothes were stored also need to be cleaned out so that all residue of the naphthalene ball is washed away. Clean the containers using an equal amount of vinegar and water.
