Abstract

In the present invention, a method and apparatus are implemented for inspecting the surfaces of ceramic tableware/pieces of ceramic crockery, said method and apparatus being characterized in that, with a single item of equipment: A--the product is illuminated by overall or zone-by-zone diffuse illumination; and B--the product is observed using one or more observation means, by causing the overall diffuse illumination or the localized diffuse illumination from at least one diffuse illumination zone adapted to make at least a selected portion of the product shiny to reflect off said product towards said one or more observation means. The invention makes it possible, with a single piece of apparatus, to show and to identify the defects, whatever they may be, using methods that are 'multi-purpose' and fully effective even in critical cases, such as a combination of complex shapes, of shininess, and of white-on-white defects, unlike the prior art.
