Conch
Conch shells are sometimes used as decoration, as decorative planters, and in cameo-making. As with other mollusk shells, they are ground up into an ingredient in porcelain. In classic Mayan art, conches are shown being utilized in many ways including as paint and ink holders for elite scribes, as bugle or trumpet, and as hand weapons (held by combatants by inserting their hands in the aperture).
