The base line for the index of refraction is the amount of directional deviation that is produced when a beam of light travels from the air into another substance. The term “high index” is a relative term. Glycerin actually has a low index of refraction when compared to motor oil. I can’t be certain but I believe that the density and opacity of a substance plays a big part in the determination of it’s relative index.
