Pe Tin
Pe Tin is a historic term used in some regions, particularly in or relating to Cornwall, England, to refer to processed or refined tin ore. It denotes tin that has been smelted and is ready for further use or trade. Unlike crude ore, pe tin represents a higher grade of tin, closer to its metallic form. The term may also be associated with particular methods of tin processing, or with the specific form or quality of tin produced in a certain area. The etymology likely links to "pe" implying a state or processed condition, combined with "tin". Historical documents pertaining to mining activities in Cornwall often mention 'pe tin' when recording quantities of tin traded or taxed. Its usage is less common in contemporary contexts, with the more general term 'tin' often preferred.
