1. A method of forming a sol gel from a sol gel-forming composition comprising:
forming the sol gel from the sol gel-forming composition, wherein the sol gel-forming composition comprises a silane solution and a catalyst solution, wherein the catalyst solution is added to the silane solution at a rate from about 1% to about 50% catalyst solution per volume per second; and
non-supercritically drying the sol gel to provide a dried silicon-based porous sol gel having no springback, wherein the dried silicon-based porous sol gel is cast in place on a structure or preformed using a mold.
