Picked up a few pieces of cast today. One is a #8 fully marked Victor, another is a #6 good health then a nice BSR 2qt sauce pan. I don't see the sauce pans very often so it was a good find.
Are cast iron cookware good "forever"?
I've never been able to get that black-mirror like finish on a cast-iron pan, much less maintain it. Mine always wind up looking a dirty, splotchy brown. I seem to get the worst results when I cook with butter, but the same thing happens with olive oil and canola oil.
And the heating source doesn't matter, I get the same results whether cooking with gas, electric or induction.
Even after a deep cleaning, the brown splotches return. I will usually keep a pan for about 5 years, then go buy a new one.
The shine was made by a fresh coat of lard, it's not normal for it to be like that. Lots of good info with this link.
