As Thomas said, Lee Sauder has a lot of knowledge on bloomerys. He, Shel Browder, and Steve Mankowski, created a DVD called from Ore to Ax wherein they smelted iron, and obviously, used it to make an ax. Currently, those three are working on another DVD about smelting the steel they used for the sharpened blade of the ax. I look forward to seeing it when it comes out. Shel Browder retired from Colonial Williamsburg and is out and about storytelling and blacksmithing. Steve Mankowski still works as a Blacksmith for Colonial Williamsburg. Lee's shop is in Lexington, Virginia. All three of these gentlemen willingly share their knowledge when asked.
