is the ability for a medium to crumble easily.
Synonyms in English
Often describing a media on paper, friability refers to the capacity of a material to crumble and separate from a support. This is frequently the result of inadequate binding in the medium. Friable media such as pastels, charcoal, and some paint may separate from a support due to abrasion or contact.
