Many people often want to know what the cast numbers or letters mean on the lids, or bottoms of cast iron cookware.

Often times a stand alone number, or letter, is simply a unique mold number.  An identifier the has no relationship to anything other than the mold it was made in.  It was used to identify and make corrections to, or to eliminate a defective master mold, when large batches were poured.

Other numbers or letters may be an indicator of the capacity or size.
