Morphology
The phrase is partially compositional: a B1 learner who knows 'soft' and 'glass' can infer a glass-like material that is soft, so there is a transparent core. However, the specific scientific sense (an amorphous, glassy solid with slow relaxation, aging, and yielding) is technical and not fully predictable from everyday senses of the words, so prior subject-matter knowledge is needed.
Etymology
Soft glass comes from real glass that becomes soft at lower heat, so glassmakers can shape it more easily. That's why the name means 'glass that is easier to work with'.
