What I have right now is Chicago Metallic. That's neither of the above right?
I am not sure which Chicago Metallic pan you have. But, several years ago, around 2006, CM used a topical (not baked in) non-stick coating called Silverstone. But by around 2008 or so, they sold two pans under the Bakalon name, one with a non-stick coating and one with a baked in coating, similar to the one used by Lloyd Pans and also by American Metalcraft. I believe that CM may have stopped selling the non-stick coated pans and now only offers the Bakalon dark anodized coated pans for baking pizzas. As evidence of this, I cite page 26 of the most recent CM catalog at http://www.cmbakeware.com/sites/default/files/pdf/012113_cm_2013_cat.pdf
. You will also note from page 25 of the catalog that CM also sells aluminum steel pans (unseasoned).
