A method of making a 3D glass article includes forming at least one marker on an edge of a 2D glass piece. The 2D glass piece is thermally reformed into a 3D glass article, where the at least one marker formed on the edge of the 2D glass piece is carried over to an edge of the 3D glass article. The 3D glass article is aligned on a support using the at least one marker on the edge of the 3D glass article. Then, the edge of the 3D glass article is finished to a final shape and dimension.
