Years ago I sent an antique cast iron cookstove off to a very well-known stove restoration business in Maine, mainly to have it converted back to wood from kerosene. To my dismay, it came back sandblasted: grayish and roughened. I applied several coats of old-fashioned stove polish/blacking, and after a few years it's regained a pretty decent black finish. It was nice to know the stove was sturdy and safe to use--and the nickel trim had all been beautifully replated--but I missed the irreplaceable smooth black patina that only comes with many years of use. I'm wondering if this treatment is standard when a stove is "reconditioned." Would be curious to hear from other readers.
