Glass is a non-porous surface, meaning it lacks tiny pores or spaces for the pencil lead to adhere to. Pencil lead is made of graphite, a material that requires a rough or porous surface to leave a mark. Since glass is smooth and non-absorbent, the graphite in the pencil cannot transfer onto the surface, resulting in no visible markings. Additionally, the hardness of the glass is much greater than that of the pencil lead, so the lead is not able to leave a visible mark on the glass surface.
