The art forms of Ancient Egypt included painting, sculpture, pottery, papyrus, architecture and hieroglyphs. Painting and sculpture reached high levels as both were highly stylized and symbolic. Paintings were produced by applying mineral pigments on plaster or stone surfaces, then sealed with varnish. Sculptures adhered to standardized human proportions. Small sculptures of vessels and amulets were carved from steatite. Pottery was also made and placed in tombs. Writing was done using papyrus, though it is fragile. Architecture used bricks, sandstone, limestone and granite, with ramps to help in construction. Hieroglyphs were the writing system with over 700 symbols, later decoded
