King Arthur Flour Oven
Built from Vermont stone with colored plaster and soapstone details, this oven is located at King Arthur Flour Baker’s Store in Norwich, Vermont and serves the wood fired classes as part of their baking school. It was built by Doug Wood from Thetford Center, Vermont. Decorative plaster by Raven Fennell. Oven core construction by Albie Barden of Maine Wood Heat and Roland Voppel from Holland. The oven contains a model 180 Le Panyol oven core. Thanks for help from Roland, Albie, Raven, Steve Busch and John Arnold.
