Produced to fit in the circular openings in the tops of wood stoves, cast-iron cookware uses a sizing system with numbers corresponding not to the actual dimensions of the piece, but to the opening size in which they fit.For example, the bottom diameter of a "6" skillet usually measures around 7 1/2 inches.The slant logo was generally of the same diameter on most pieces, with exceptions made for pieces like lids, where a reduced size version was used.There exist a few pieces with what is sometimes for lack of a better term called a medium slant logo.

Instead of using traditional size numbering, some brands during certain periods mark the dimensions on the piece in inches, such as “6-1/2 Inch Skillet” or “10 5/8 IN.” Manufacturers often cast a pattern number -- also known as a catalog number -- into each piece with a small group of numbers or numbers with letters, such as “701” or “1053C.” They usually appear on the underside of the cookware and identify the mold used to cast the piece.Her work has appeared in informative guides on student housing cooperatives and sustainable building alternatives.Other areas of specialty include technology, health, gardening and cooking.Slightly smaller and proportionally different from the normal slant, it may have been the result of a prototype pattern being used for actual production.The slant logo was seen on both heat ringed and in rare cases smooth bottom skillets, as well as on pans marked "ERIE" and "ERIE, PA, U. A.", being referred to by collectors as "Slant Erie" and "Slant EPU", respectively. Later, around 1920, the slant logo was updated, with the lettering being changed to a block style.
