DATA: Crystalline structures of Ice (H20) and Silver Iodide (AgI)
CLOUD SEEDING STRUCTURES explore the concept of cloud seeding - a form of intentional weather modification - defined as the "attempt to change the amount or type of precipitation that falls from clouds, by dispersing substances into the air that serve as cloud condensation or ice nuclei, which alter the microphysical processes within the cloud." Silver Iodide (AgI) is a compound commonly used in cloud seeding, because it shares a similar crystalline structure to that of ice crystals. The sculptures are enlarged versions of these hexagonal molecular structures. The ice structure is made of redwood reclaimed from a water tank from Petaluma, and the steel structure is patinated to resemble silver iodide mineral in it's naturally occurring state.
