Some info:
Vintage yellow Belgian slate (Yellow Coticule) in sizes 149x15x6mm. Yellow Coticule contains up to 42% granate grains ranging in size from 5 to 15 microns. Compared to BBW, Yellow Coticule is soft and brittle and is used as bonded with blue stone (glued or cut from a solid natural piece) to improve performance.
Work with Belgian yellow slate by wetting the surface with clean water. Depending on the type of blade steel being processed, a suspension can be induced on the stone with varying degrees of intensity. The suspension can be preliminarily applied by rubbing the working surface of the cat with a piece of the same stone or other abrasive bar. As a rule, work with Belgian yellow shale is carried out in two stages: first on a suspension, and then on a clean stone moistened with water.
Sometimes oil is also used for finishing on these stones, which is also permissible, although the manufacturer does not recommend this format of work.
It gives a very high sharpness, works very quickly, does not form a burr, and absolutely does not get greasy. A stunning, incomparable feeling from the sharpening itself, a unique response when passing a knife that no other stone has - all this makes the Belgian shale incomparable with any other existing artificial or natural abrasive. The stone is absolutely amazing in the pleasure of the very process of working with it.
