The sand/clay mixture is often contained in a metal flask or mold in order to be able to compact the material to a dense state for optimal pouring results. Due to its malleable texture, sand casting can be used to replicate intricate objects by pressing the object into the sand to leave a negative impression of the design that is then filled with your molten metal.
History The first recorded instance of sandpaper was in 13th-century China when crushed shells, seeds, and sand were bonded to parchment using natural gum. In the Bible, King Solomon is mentioned to have used a mysterious abrasive called shamir allowing the king to build his temple (e.g. cut huge blocks of stone) without using iron tools, since the temple was meant to be a place of peace and ...
