I removed the unsourced mention of vitrification because CAS freezers do not use vitrification, nor can CAS technology result in vitrification without much lower temperatures and higher cryoprotectant concentrations. Cryobiologist (talk) 22:23, 5 December 2012 (UTC)
(A) According to the glass transition article, the temperature of vitrification is always below the melting point, so how is it possible for anything which is vitrified to not also be technically frozen?
