Morphology
The phrase names a type of sponge characterized by a glass-like (siliceous) skeleton, so a learner who knows 'glass' and 'sponge' can infer it denotes a sponge with glass-like properties. This is a descriptive noun‑noun compound following normal compositional patterns rather than an idiom, making the meaning readily derivable for B1 learners.
Etymology
Glass sponge is a name for a sea animal that is a sponge with a 'skeleton' made of many tiny, glass-like threads. So the name helps you remember it means a sponge with a fragile, glass-like internal frame.
