The present invention relates to the application of laser technology for amending or restoring existing surface defects or pathologies on vitreous surfaces, such as glasses and glazes, which may be attached to substrates such as ceramics or other support materials.

Device and methods to restore fissured areas of vitreous surfaces are disclosed. A laser beam is generated by a laser source. A controller controls the direction of the laser beam and shapes the spot-size of the laser beam according to sizes of the fissured areas. The laser beam is directed to the fissured areas to melt the vitreous surfaces around the fissured areas and fuse the melted vitreous surfaces in the fissured areas. The proposed methods may be used for amending/restoring existing surface pathologies on vitreous surfaces, such as glasses and glazes, which may be attached to non-vitreous substrates, such as ceramics or other support materials.
