ABSTRACT:
A coated glass article which may be heat strengthened with reduced variability in sheet resistance is disclosed. A multi-layer coating is formed on a glass substrate including a barrier applied on the glass substrate, base layer of a substantially undoped metal oxide applied over the barrier layer, and an electrically conductive layer of a doped metal oxide applied directly on the base layer. The same source metal is used for the base layer and the electrically conductive layer.
