Copper is the earliest known metal that was used by humankind. As early as the late the Neolithic Age, ancient people discovered natural copper which has a golden color and luster and high ductility. They cherished the metal and made small adornments or knives with it. Unfortunately, copper is not hard enough to be applied extensively. Later on, people mastered the technology to smelt copper from ore and add appropriate stannum or plumbum into it to increase its hardness and decrease its melting point. Thus, the processed metal, easier to be founded and resistant to abrasiveness, can be used in manufacturing production instruments, household utensils and weaponry. It is now what we call bronze.Features:* Automatically Mark your Reading Progress* Six Bookmarks Capacity* full pagination,like the original printed editions* each title includes page numbers* Table of Contents incorporates one click navigation.* remember your reading progress* Swipe to turn the page.* add bookmark progressFor instruction on the app, Please view info.SupportIf you have any technical problems please email us at SUPPORT@FEETAN.COM before you post a review.
