Bronze is a mixture of metals, primarily copper that is poured into a mould. The higher the copper content, the higher the quality of bronze. Bronze has been produced since before 3000 BC, originally mostly for weapons and armor. It is incredibly durable, making it a popular choice for bronze markers, flower vases, statues and plaques. Bronze markers are available in a variety of sizes with different design elements available for personalization. A bronze marker needs to be attached to either a concrete or granite base for added stability.
