Bake a Round®
The Bake a Round® is a glass tube used for baking bread. The tube is made of PYREX® glass and comes with a chrome plated steel holder. The Bake a Round® was manufactured by the Corning Glass Company during the 1970s. It is no longer manufactured and so the only sources of supply are thrift or antique shops or ebay. The current price on ebay varies from $10 to $30 depending on it's condition (new/used) and whether it comes with the original box, instruction sheet and recipes.
NOTE: You can use most recipes for 1 pound loafs such at the ones here.
