Method of producing a dry airgel comprising the steps of precipitating a colloidal substance in a liquid such as a gel, confining the resulting product in a pressure vessel, applying heat to it until the liquid in the gel has reached a temperature at which the surface tension of the liquid is so small as to cause non-substantial shrinkage of the gel when the liquid evaporates, maintaining such temperature, and then extracting the vapor from the pressure vessel at an insufficient speed to damage the gel.
