AI Technical Summary

Problems solved by technology

[0003] One problem customers face is cleaning the components of a gas cooker after use, especially after food (such as cheese, sauces, oil, fat, etc.) has splattered from the pan or pan and burned onto the surface of the components (such as the top plate of a gas cooker or the burner cap of a gas burner of a gas cooker)

[0004] A disadvantage of said coatings is that they are usually applied in two steps and require high firing temperatures during their manufacturing process, which leads to high costs and labor-intensive
