A hyaline substance is one with a glassy appearance. The word is derived from {{langx|el|ὑάλινος|translit=hyálinos|lit=transparent}}, and {{langx|el|ὕαλος|translit=hýalos|lit=crystal, glass|label=none}}.[http://www.mushroomthejournal.com/greatlakesdata/Terms/hyali599.html IMA Mycological Glossary: Hyaline].[https://www.merriam-webster.com/dictionary/hyaline Hyaline definition] in Merriam Webster Dictionary
Histopathology
Hyaline cartilage is named after its glassy appearance on fresh gross pathology.{{cite web |last1=Adele |first1=Knibbs |title=The Leeds Histology Guide |url=https://www.histology.leeds.ac.uk/bone/cartilage_types.php |access-date=27 October 2018 |language=en |date=2003}} On light microscopy of H&E stained slides, the extracellular matrix of hyaline cartilage looks homogeneously pink, and the term "hyaline" is used to describe similarly homogeneously pink material besides the cartilage. Hyaline material is usually acellular and proteinaceous. For example, arterial hyaline is seen in aging, high blood pressure, diabetes mellitus and in association with some drugs (e.g. calcineurin inhibitors). It is bright pink with PAS staining.
