Craig, when I started into this, I seasoned everything. Began by using PAM, and finally settled on Crisco Shortening.
I stacked pans on the racks, and after 4 years give or take, I began to see color changes to brownish and a slight musty smell.
I got to the point where I realized I will never use them all, not even 1/16th of them if that, so I switched it up to mineral oil.
Can always do a seasoning down the road if I must.
Most of my users are less than perfect specimens with light pitting or sulphur pitting on bottoms, and my bacon skillet is a newer Wagner #12... so...
My cornbread skillet was my Mom's and one of the pans that got me into this obsession... lol.
She reclaimed it after I restored it, (it had been sitting in her basement for about 30 years).... and since her passing it is now mine again
