I’m completely new to smithing. I’m just trying to get started and I’m starting small. I am looking at getting a small gas forge (Firebox – 4" h x 4-1/2" w x 13-1/2" l ). My shop is small, 15’ x 10’, the shop has the windows in the front and doors on both ends. Will the Windows and doors provide enough air circulation or should I look into venting the forge? Thanks for your time and help.
