In literature, slate functions diversely as both a tangible material and a symbolic device. As a building material, it provides vivid texture and durability in descriptions of roofs and structures, evoking a sense of stability and timelessness ([1], [2], [3]). As an instrument for communication and education, it appears as the surface upon which characters write, draw, and record their thoughts—a metaphor for new beginnings or the clearing of past errors ([4], [5], [6]). Additionally, the characteristic hues of slate lend themselves to evocative imagery, from the bleak, splintered stars in a dark night sky to the cool, penetrating eyes of a character, thus enriching the narrative’s visual palette ([7], [8], [9]).
