The invention relates to the technical field of glass and stone processing, in particular to a processing method for engraving glass and stone mosaics.The operating method includes the following steps that float glass is used for transferring colored glaze, the glass is cut into granules of different specifications, and the granules are subjected to high-temperature firing in a roller kiln so that all edges of the granules can be round and smooth; the glaze at the bottoms of the glass granules is fused with the glass after being subjected to high-temperature firing, the front faces of the granules reflect clear colors, and the glass granules of various specifications are spliced into a mosaic product; an adhesive film is pasted on the surface of the mosaic product, and then various designed patterns are engraved on the adhesive film through a laser engraving machine; high-pressure sand blasting is carried out on the surface of the mosaic product with the engraved patterns according to a high-pressure sand blasting technology, and the mosaics are obtained.An original backward process is changed, production efficiency is substantially improved, energy-saving and emission-reducing environment-friendly production is achieved, and harm caused by toxic substances to the environment and workers is avoided.
