The Annealing Box is another innovative tool from metalsmith Jay Whaley. To anneal metal properly, you need some darkness so that you can watch your metal change color and cease the application of heat at the right time. Made from stainless steel, the Annealing Box measures 12” wide x 6” deep by 6” high. A 12” x 6” soft Solderite board is included. Provided unassembled, though it assembles quickly with wing screws.
