Vitrification

By contrast with freezing, which produces crystallization and other structural alterations, vitrification cools substances to form a glass without disturbing their structure.

In the context of Cryonics, vitrification is intended to fully maintain the information encoded in the patient's brain. Currently, vitrification is applied only to Alcor neuro (brain) patients, but research is in progress to apply vitrication to the whole body at Alcor and the Cryonics Institute.
