Abstract
A glass article includes at least one glass substrate on which a stack of layers is deposited. The stack includes at least one layer consisting of a layer of silicon nitride of formulation SiNx, in which x is less than 1.25. The physical thickness of the SiNx layer is between 5 and 50 nm. The light reflection of the glass article, measured on the side of the substrate on which the stack is deposited, is greater than 20%.
