A composite article comprises a first glass layer, a silicone layer, a second glass layer, and an organic layer. The silicone layer is disposed adjacent to the first glass layer. The silicone layer includes a cured silicone composition. The second glass layer is disposed adjacent to the silicone layer, spaced from and substantially parallel to the first glass layer. The organic layer is disposed adjacent to the second glass layer, spaced from and substantially parallel to the silicone layer. The organic layer includes a cured organic composition. A method of making a composite article including a first glass layer and a polymeric layer disposed adjacent to the first glass layer includes providing a dual-compartment chamber. The chamber includes a first compartment and a second compartment separated by a polymeric separator. The separator can be manipulated through pressure differentials between the compartments. Pressure is applied to at least one of the silicone layer and the first glass layer with the polymeric separator.
