Aspirin in polarized light

These are two samples of Aspirin or acetylsalicylic acid under the microscope. The lower one is a single crystal in polarized light with the typical colors and mineralogical habit. The upper sample was overheated in the heating cupboard. I don’t know what is it now, but it has spacy colors and forms.
