By about 1000 CE, the Hohokam were the first to master acid etching, daubing shells with pitch and bathing them in acid most likely made out of fermented cactus juice. [21] Artisans produced jewelry from shell, stone, and bone, and began to carve stone figures.
The Hohokam people primarily used these large shells to make bracelets and rings; the center of the shell was generally removed immediately after the bivalves were collected, and before transport back to the Hohokam villages in the Gila Basin.

The Hohokam also produced jewelry made of raw shell imported from northern Mexico which they traded. [2] [4] The reason for which the Hohokam abandoned the village is unknown. There was a radical decline in the procurement and trade of raw shell from Mexico and its manufacture into jewelry.
Etching is also used in the manufacturing of printed circuit boards and semiconductor devices, and in the preparation of metallic specimens for microscopic observation. Prior to 1100 AD, the New World Hohokam culture independently utilized the technique of acid etching in marine shell designs. [31]
