Cowl (oast)
From Wikipedia, the free encyclopedia
A cowl is a device used on a kiln to keep the weather out of and to induce a flow of air through the kiln. They are normally associated with oasts but can also be found on breweries (Letheringsett, Norfolk), maltings (Ware, Hertfordshire; Hadlow, Kent) and watermills (East Linton, East Lothian).[1][2]
