A glass sheet is formed using a roll-to-roll glass soot deposition and sintering process. The glass sheet formation involves forming a first glass soot layer on a deposition surface of a soot-receiving device, removing the first glass soot layer from the deposition surface, and forming a second glass soot layer on the unsupported first glass soot layer. The resulting composite glass soot sheet is heated to form a sintered glass sheet. The glass sheet can be a substantially homogeneous glass sheet or a composite glass sheet having layer-specific attributes.

The method for making a glass sheet of claim 1, wherein the first soot sheet is not sintered during the heating step such that the glass sheet is formed on an unsintered first soot sheet. 3. The method for making a glass sheet of claim 1, wherein the second glass soot particles are deposited on at least one of the contact surface and the free surface to form a composite soot sheet after the soot layer has been removed from the deposition surface. 4. The method for making a glass sheet of claim 1, wherein the first glass soot particles have a first sintering temperature and the second glass soot particles have a second sintering temperature, wherein the first sintering temperature is higher than the second sintering temperature. 5. The method for making a glass sheet of claim 1, wherein the depositing of the second glass soot particles forms a second soot layer having a major surface in contact with at least one of the contact surface and the free surface of the first soot sheet. 6. The method for making a glass sheet of claim 5, wherein the glass sheet is formed with a major surface in contact with at least one of the contact surface and the free surface of the first soot sheet. 7. The method for making a glass sheet of claim 1, wherein the first soot sheet is a free-standing, unsupported soot sheet.
