Rules: Be helpful when you can, be respectful always, and keep cooking bacon.

More rules may come as the community grows, but for now, I'll remove spam or anything obviously mean-spirited, and leave it at that.

A true seasoned surface will only form properly at temperatures well in excess of the 350-375 degree F temperature that some manufacturers recommend for seasoning cast iron. Low temperatures do not completely polymerize and break down oil and will leave a brown, somewhat sticky pan instead of a black, non-stick one. 400-500 degrees F is the effective range for seasoning.

From Dave Arnold's excellent blog 'Cooking Issues'
