Superglue should not be placed on a hot plate because it can get too hot and generate HCN (a toxic gas). List items considered to be a porous surface. Prints that are not readily visible are commonly referred to as: Are sent to the AFIS database electronically, have eliminated the need for inked prints on paper cards, are captured when the subject's fingers and palms are placed onto a glass platen.
