Abstract
Methods of forming a sheet glass product comprising a plurality of growth-limited glass bump spacers. According to the methods, a glass pane of the sheet glass product is irradiated with laser radiation to locally heat the glass pane at a plurality of spacer localities and induce growth of a plurality of glass bump spacers in the glass pane. The growth of the plurality of glass bump spacers is limited by utilizing a growth-limiting plate comprising a scattering surface portion. The scattering surface portion of the growth-limiting plate mitigates damage to the growth-limiting plate and may also mitigate damage to the glass pane. Vacuum insulated glass products and systems for forming a growth-limited sheet glass product are also provided.
