An improved process for making a multiple pane fire resistant window whose spacings are filled with an aqueous gel possessing multiple carbon bonds, wherein the improvement comprises placing a thin layer of an adherence agent on the contact surface of the panes, prior to placing the aqueous gel in the spacing. The adherence gel is selected from the group consisting essentially of organic titanates, organic zirconates, and silanes able to react with the aqueous gel's multiple carbon bonds.
