Morphology
The meaning 'a clay used to remove color' is directly derivable from combining 'bleach' (to remove color) with 'clay' (a type of earth); a B1 learner who knows both constituents can infer it denotes clay used for bleaching or decolorizing. The compound follows a straightforward noun-noun composition and mirrors cross-linguistic patterns for naming materials by function, so it is transparent despite being a technical term.
Etymology
Bleaching clay comes from the idea of bleaching ('making pale') and clay (a soft earth) that soaks up colour like a sponge. That's why today bleaching clay means a clay used to remove colour from oils and make them clear.
