Metal grains are formed in the liquid metal and on the walls of the mold As the liquid metal solidifies dendrites are formed that are maintained even after the solidification of the casting Other defects produced in the microstructure are inclusions large voids and pinholes in the casting due to the entrapped and soluble gases
Without the studs penetrating the concrete the letters would soon come loose and disappear A better way although far more costly would be to embed the letters using a stabilizer plate above For outdoor applications stainless steel would be the material of choice

Most copper ores contain only a small percentage of copper metal bound up within valuable ore minerals with the remainder of the ore being unwanted rock or gangue minerals typically silicate minerals or oxide minerals for which there is often no value In some cases tailings have been retreated to recover lost value as the technology for recovering copper has improved
Modern copper smelters use processed copper ore fed into a flash furnace typically fired by oxygen which produces blister copper being further processed in a converter furnace Molten copper is poured from here into rectangular moulds the resulting ingots subjected to electrolysis producing a metal of 999 purity Copper can be recycled indefinitely without the base metal being compromised
