A sectional curved article e.g. an automotive window is made by cutting a piece of glass, shaping the piece of glass, cutting the shaped piece to provide inner and outer segments. The edges of the segments are seamed, and the segments chemically tempered to provide a sectional curved automotive window having an opening in the outer segment to receive the inner segment.
