Mosaics Made From Salton Sea Barnacle Shells

These Are NOT Paintings! They Are Mosaics

The Artist

Jeff Geraci is a scientist who has studied Salton Sea for over 20 years, and now he's developed a very unique method for creating mosaics out of crushed barnacle shells collected from Salton Sea. He finds this mosaic technique much more challenging than painting, and there's a lot more time involved as well. But unlike paints that can be bought at the store, these barnacle shells must go through an extensive process before they can be used

The Medium

Jeff makes all of his own medium by hand. It's an arduous process, and each mosaic requires between 50,000 and 100,000 barnacles, Barnacles need to be cleaned, disinfected, rinsed, sunbleached, sorted, sieved, crushed, pigmented, and sieved again before they can be used. These unique art works are truly one of a kind.

The Inspiration

Jeff knew that there had to be a use for the discarded barnacle shells at Salton Sea. He first experimented with them as a building material, and then tried to create an apparatus that would control storm water pollution. In the end, he discovered that the best use for the shells was to create mosaic art and sculptures.
