Permanent mark maker on glass

The utility model relates to a permanent mark maker on glass. The utility model is composed of a wooden plate, a thermal insulation layer, an insulating layer, heating element, felt, etc. A handle is installed on the housing of the utility model, a temperature control knob is installed on one side of the housing, and liquid filling holes are arranged in the utility model. When the utility model is used, a power supply is switched on; after the heating element becomes hot, a cere is softened, and thus, the felt is caused to tightly stick to the surface of glass; then, etching solution seeps onto the felt along the liquid filling holes, the etching solution seeps onto the surface of the glass through the felt and acts on a pattern needing etching. The utility model is convenient to operate, just three to five minutes are needed in an etching process, and images produced are homogeneous and clear, without rough edges; thus, the utility model is atoxic and doesn't generate pollution.
