Abstract
A water pitcher system that includes a water receiving aperture configured to allow water to be delivered into an interior water storage volume defined by a base and at least one upwardly extending wall extending upward from the base. The at least one upwardly extending wall includes an inner fluid facing wall section having an inner fluid facing surface and an outer user facing wall section having an exterior, user facing surface where the inner fluid facing wall section and the outer user facing wall section are each composites of a plastic substrate and a glass layer, typically deposited by vapor deposition or blow-molding, onto the plastic substrate. The inner fluid facing surface and the outer user facing surface are the glass layers.
